NAME

       smb.conf - The configuration file for the Samba suite


SYNOPSIS

       The smb.conf file is a configuration file for the Samba suite.
       smb.conf contains runtime configuration information for the Samba
       programs. The smb.conf file is designed to be configured and
       administered by the swat(8) program. The complete description of the
       file format and possible parameters held within are here for reference
       purposes.


FILE FORMAT

       The file consists of sections and parameters. A section begins with the
       name of the section in square brackets and continues until the next
       section begins. Sections contain parameters of the form:

           name = value

       The file is line-based - that is, each newline-terminated line
       represents either a comment, a section name or a parameter.

       Section and parameter names are not case sensitive.

       Only the first equals sign in a parameter is significant. Whitespace
       before or after the first equals sign is discarded. Leading, trailing
       and internal whitespace in section and parameter names is irrelevant.
       Leading and trailing whitespace in a parameter value is discarded.
       Internal whitespace within a parameter value is retained verbatim.

       Any line beginning with a semicolon (";") or a hash ("#") character is
       ignored, as are lines containing only whitespace.

       Any line ending in a "\" is continued on the next line in the customary
       UNIX fashion.

       The values following the equals sign in parameters are all either a
       string (no quotes needed) or a boolean, which may be given as yes/no,
       0/1 or true/false. Case is not significant in boolean values, but is
       preserved in string values. Some items such as create masks are
       numeric.


SECTION DESCRIPTIONS

       Each section in the configuration file (except for the [global]
       section) describes a shared resource (known as a "share"). The section
       name is the name of the shared resource and the parameters within the
       section define the shares attributes.

       There are three special sections, [global], [homes] and [printers],
       which are described under special sections. The following notes apply
       to ordinary section descriptions.

       A share consists of a directory to which access is being given plus a
       description of the access rights which are granted to the user of the
       service. Some housekeeping options are also specifiable.

       Sections are either file share services (used by the client as an
       extension of their native file systems) or printable services (used by
       the client to access print services on the host running the server).

       Sections may be designated guest services, in which case no password is
       required to access them. A specified UNIX guest account is used to
       define access privileges in this case.

       Sections other than guest services will require a password to access
       them. The client provides the username. As older clients only provide
       passwords and not usernames, you may specify a list of usernames to
       check against the password using the user = option in the share
       definition. For modern clients such as Windows 95/98/ME/NT/2000, this
       should not be necessary.

       The access rights granted by the server are masked by the access rights
       granted to the specified or guest UNIX user by the host system. The
       server does not grant more access than the host system grants.

       The following sample section defines a file space share. The user has
       write access to the path /home/bar. The share is accessed via the share
       name foo:

                [foo]
                path = /home/bar
                read only = no

       The following sample section defines a printable share. The share is
       read-only, but printable. That is, the only write access permitted is
       via calls to open, write to and close a spool file. The guest ok
       parameter means access will be permitted as the default guest user
       (specified elsewhere):

                [aprinter]
                path = /usr/spool/public
                read only = yes
                printable = yes
                guest ok = yes


SPECIAL SECTIONS

   The [global] section
       Parameters in this section apply to the server as a whole, or are
       defaults for sections that do not specifically define certain items.
       See the notes under PARAMETERS for more information.

   The [homes] section
       If a section called [homes] is included in the configuration file,
       services connecting clients to their home directories can be created on
       the fly by the server.

       When the connection request is made, the existing sections are scanned.
       If a match is found, it is used. If no match is found, the requested
       section name is treated as a username and looked up in the local
       password file. If the name exists and the correct password has been
       given, a share is created by cloning the [homes] section.

       Some modifications are then made to the newly created share:

       o   The share name is changed from homes to the located username.

       o   If no path was given, the path is set to the user's home directory.

       If you decide to use a path = line in your [homes] section, it may be
       useful to use the %S macro. For example:

           path = /data/pchome/%S

       is useful if you have different home directories for your PCs than for
       UNIX access.

       This is a fast and simple way to give a large number of clients access
       to their home directories with a minimum of fuss.

       A similar process occurs if the requested section name is "homes",
       except that the share name is not changed to that of the requesting
       user. This method of using the [homes] section works well if different
       users share a client PC.

       The [homes] section can specify all the parameters a normal service
       section can specify, though some make more sense than others. The
       following is a typical and suitable [homes] section:

           [homes]
           read only = no

       An important point is that if guest access is specified in the [homes]
       section, all home directories will be visible to all clients without a
       password. In the very unlikely event that this is actually desirable,
       it is wise to also specify read only access.

       The browseable flag for auto home directories will be inherited from
       the global browseable flag, not the [homes] browseable flag. This is
       useful as it means setting browseable = no in the [homes] section will
       hide the [homes] share but make any auto home directories visible.

   The [printers] section
       This section works like [homes], but for printers.

       If a [printers] section occurs in the configuration file, users are
       able to connect to any printer specified in the local host's printcap
       file.

       When a connection request is made, the existing sections are scanned.
       If a match is found, it is used. If no match is found, but a [homes]
       section exists, it is used as described above. Otherwise, the requested
       section name is treated as a printer name and the appropriate printcap
       file is scanned to see if the requested section name is a valid printer
       share name. If a match is found, a new printer share is created by
       cloning the [printers] section.

       A few modifications are then made to the newly created share:

       o   The share name is set to the located printer name

       o   If no printer name was given, the printer name is set to the
           located printer name

       o   If the share does not permit guest access and no username was
           given, the username is set to the located printer name.

       The [printers] service MUST be printable - if you specify otherwise,
       the server will refuse to load the configuration file.

       Typically the path specified is that of a world-writeable spool
       directory with the sticky bit set on it. A typical [printers] entry
       looks like this:

           [printers]
           path = /usr/spool/public
           guest ok = yes
           printable = yes

       All aliases given for a printer in the printcap file are legitimate
       printer names as far as the server is concerned. If your printing
       subsystem doesn't work like that, you will have to set up a
       pseudo-printcap. This is a file consisting of one or more lines like
       this:

           alias|alias|alias|alias...

       Each alias should be an acceptable printer name for your printing
       subsystem. In the [global] section, specify the new file as your
       printcap. The server will only recognize names found in your
       pseudo-printcap, which of course can contain whatever aliases you like.
       The same technique could be used simply to limit access to a subset of
       your local printers.

       An alias, by the way, is defined as any component of the first entry of
       a printcap record. Records are separated by newlines, components (if
       there are more than one) are separated by vertical bar symbols (|).

       Note
       On SYSV systems which use lpstat to determine what printers are defined
       on the system you may be able to use printcap name = lpstat to
       automatically obtain a list of printers. See the printcap name option
       for more details.


USERSHARES

       Starting with Samba version 3.0.23 the capability for non-root users to
       add, modify, and delete their own share definitions has been added.
       This capability is called usershares and is controlled by a set of
       parameters in the [global] section of the smb.conf. The relevant
       parameters are :

       usershare allow guests
           Controls if usershares can permit guest access.

       usershare max shares
           Maximum number of user defined shares allowed.

       usershare owner only
           If set only directories owned by the sharing user can be shared.

       usershare path
           Points to the directory containing the user defined share
           definitions. The filesystem permissions on this directory control
           who can create user defined shares.

       usershare prefix allow list
           Comma-separated list of absolute pathnames restricting what
           directories can be shared. Only directories below the pathnames in
           this list are permitted.

       usershare prefix deny list
           Comma-separated list of absolute pathnames restricting what
           directories can be shared. Directories below the pathnames in this
           list are prohibited.

       usershare template share
           Names a pre-existing share used as a template for creating new
           usershares. All other share parameters not specified in the user
           defined share definition are copied from this named share.

       To allow members of the UNIX group foo to create user defined shares,
       create the directory to contain the share definitions as follows:

       Become root:

           mkdir /usr/local/samba/lib/usershares
           chgrp foo /usr/local/samba/lib/usershares
           chmod 1770 /usr/local/samba/lib/usershares

       Then add the parameters

                usershare path = /usr/local/samba/lib/usershares
                usershare max shares = 10 # (or the desired number of shares)

       to the global section of your smb.conf. Members of the group foo may
       then manipulate the user defined shares using the following commands.

       smbnet usershare add sharename path [comment] [acl] [guest_ok=[y|n]]
           To create or modify (overwrite) a user defined share.

       smbnet usershare delete sharename
           To delete a user defined share.

       smbnet usershare list wildcard-sharename
           To list user defined shares.

       smbnet usershare info wildcard-sharename
           To print information about user defined shares.


PARAMETERS

       Parameters define the specific attributes of sections.

       Some parameters are specific to the [global] section (e.g., security).
       Some parameters are usable in all sections (e.g., create mask). All
       others are permissible only in normal sections. For the purposes of the
       following descriptions the [homes] and [printers] sections will be
       considered normal. The letter G in parentheses indicates that a
       parameter is specific to the [global] section. The letter S indicates
       that a parameter can be specified in a service specific section. All S
       parameters can also be specified in the [global] section - in which
       case they will define the default behavior for all services.

       Parameters are arranged here in alphabetical order - this may not
       create best bedfellows, but at least you can find them! Where there are
       synonyms, the preferred synonym is described, others refer to the
       preferred synonym.


VARIABLE SUBSTITUTIONS

       Many of the strings that are settable in the config file can take
       substitutions. For example the option "path = /tmp/%u" is interpreted
       as "path = /tmp/john" if the user connected with the username john.

       These substitutions are mostly noted in the descriptions below, but
       there are some general substitutions which apply whenever they might be
       relevant. These are:

       %U
           session username (the username that the client wanted, not
           necessarily the same as the one they got).

       %G
           primary group name of %U.

       %h
           the Internet hostname that Samba is running on.

       %m
           the NetBIOS name of the client machine (very useful).

           This parameter is not available when Samba listens on port 445, as
           clients no longer send this information. If you use this macro in
           an include statement on a domain that has a Samba domain controller
           be sure to set in the [global] section smb ports = 139. This will
           cause Samba to not listen on port 445 and will permit include
           functionality to function as it did with Samba 2.x.

       %L
           the NetBIOS name of the server. This allows you to change your
           config based on what the client calls you. Your server can have a
           "dual personality".

       %M
           the Internet name of the client machine.

       %R
           the selected protocol level after protocol negotiation. It can be
           one of CORE, COREPLUS, LANMAN1, LANMAN2 or NT1.

       %d
           the process id of the current server process.

       %a
           The architecture of the remote machine. It currently recognizes
           Samba (Samba), the Linux CIFS file system (CIFSFS), OS/2, (OS2),
           Windows for Workgroups (WfWg), Windows 9x/ME (Win95), Windows NT
           (WinNT), Windows 2000 (Win2K), Windows XP (WinXP), Windows XP
           64-bit(WinXP64), Windows 2003 including 2003R2 (Win2K3), and
           Windows Vista (Vista). Anything else will be known as UNKNOWN.

       %I
           the IP address of the client machine.

       %i
           the local IP address to which a client connected.

       %T
           the current date and time.

       %D
           name of the domain or workgroup of the current user.

       %w
           the winbind separator.

       %$(envvar)
           the value of the environment variable envar.

       The following substitutes apply only to some configuration options
       (only those that are used when a connection has been established):

       %S
           the name of the current service, if any.

       %P
           the root directory of the current service, if any.

       %u
           username of the current service, if any.

       %g
           primary group name of %u.

       %H
           the home directory of the user given by %u.

       %N
           the name of your NIS home directory server. This is obtained from
           your NIS auto.map entry. If you have not compiled Samba with the
           --with-automount option, this value will be the same as %L.

       %p
           the path of the service's home directory, obtained from your NIS
           auto.map entry. The NIS auto.map entry is split up as %N:%p.

       There are some quite creative things that can be done with these
       substitutions and other smb.conf options.


NAME MANGLING

       Samba supports name mangling so that DOS and Windows clients can use
       files that don't conform to the 8.3 format. It can also be set to
       adjust the case of 8.3 format filenames.

       There are several options that control the way mangling is performed,
       and they are grouped here rather than listed separately. For the
       defaults look at the output of the testparm program.

       These options can be set separately for each service.

       The options are:

       case sensitive = yes/no/auto
           controls whether filenames are case sensitive. If they aren't,
           Samba must do a filename search and match on passed names. The
           default setting of auto allows clients that support case sensitive
           filenames (Linux CIFSVFS and smbclient 3.0.5 and above currently)
           to tell the Samba server on a per-packet basis that they wish to
           access the file system in a case-sensitive manner (to support UNIX
           case sensitive semantics). No Windows or DOS system supports
           case-sensitive filename so setting this option to auto is that same
           as setting it to no for them. Default auto.

       default case = upper/lower
           controls what the default case is for new filenames (ie. files that
           don't currently exist in the filesystem). Default lower. IMPORTANT
           NOTE: This option will be used to modify the case of all incoming
           client filenames, not just new filenames if the options case
           sensitive = yes, preserve case = No, short preserve case = No are
           set. This change is needed as part of the optimisations for
           directories containing large numbers of files.

       preserve case = yes/no
           controls whether new files (ie. files that don't currently exist in
           the filesystem) are created with the case that the client passes,
           or if they are forced to be the default case. Default yes.

       short preserve case = yes/no
           controls if new files (ie. files that don't currently exist in the
           filesystem) which conform to 8.3 syntax, that is all in upper case
           and of suitable length, are created upper case, or if they are
           forced to be the default case. This option can be used with
           preserve case = yes to permit long filenames to retain their case,
           while short names are lowercased. Default yes.

       By default, Samba 3.0 has the same semantics as a Windows NT server, in
       that it is case insensitive but case preserving. As a special case for
       directories with large numbers of files, if the case options are set as
       follows, "case sensitive = yes", "case preserve = no", "short preserve
       case = no" then the "default case" option will be applied and will
       modify all filenames sent from the client when accessing this share.


NOTE ABOUT USERNAME/PASSWORD VALIDATION

       There are a number of ways in which a user can connect to a service.
       The server uses the following steps in determining if it will allow a
       connection to a specified service. If all the steps fail, the
       connection request is rejected. However, if one of the steps succeeds,
       the following steps are not checked.

       If the service is marked "guest only = yes" and the server is running
       with share-level security ("security = share", steps 1 to 5 are
       skipped.

        1.  If the client has passed a username/password pair and that
           username/password pair is validated by the UNIX system's password
           programs, the connection is made as that username. This includes
           the \\server\service%username method of passing a username.

        2.  If the client has previously registered a username with the system
           and now supplies a correct password for that username, the
           connection is allowed.

        3.  The client's NetBIOS name and any previously used usernames are
           checked against the supplied password. If they match, the
           connection is allowed as the corresponding user.

        4.  If the client has previously validated a username/password pair
           with the server and the client has passed the validation token,
           that username is used.

        5.  If a user = field is given in the smb.conf file for the service
           and the client has supplied a password, and that password matches
           (according to the UNIX system's password checking) with one of the
           usernames from the user = field, the connection is made as the
           username in the user = line. If one of the usernames in the user =
           list begins with a @, that name expands to a list of names in the
           group of the same name.

        6.  If the service is a guest service, a connection is made as the
           username given in the guest account = for the service, irrespective
           of the supplied password.


EXPLANATION OF EACH PARAMETER

       abort shutdown script (G)

           This a full path name to a script called by smbd(8) that should
           stop a shutdown procedure issued by the shutdown script.

           If the connected user posseses the SeRemoteShutdownPrivilege,
           right, this command will be run as user.

           Default: abort shutdown script = ""

           Example: abort shutdown script = /sbin/shutdown -c

       acl check permissions (S)

           This boolean parameter controls what smbd(8)does on receiving a
           protocol request of "open for delete" from a Windows client. If a
           Windows client doesn't have permissions to delete a file then they
           expect this to be denied at open time. POSIX systems normally only
           detect restrictions on delete by actually attempting to delete the
           file or directory. As Windows clients can (and do) "back out" a
           delete request by unsetting the "delete on close" bit Samba cannot
           delete the file immediately on "open for delete" request as we
           cannot restore such a deleted file. With this parameter set to true
           (the default) then smbd checks the file system permissions directly
           on "open for delete" and denies the request without actually
           deleting the file if the file system permissions would seem to deny
           it. This is not perfect, as it's possible a user could have deleted
           a file without Samba being able to check the permissions correctly,
           but it is close enough to Windows semantics for mostly correct
           behaviour. Samba will correctly check POSIX ACL semantics in this
           case.

           If this parameter is set to "false" Samba doesn't check permissions
           on "open for delete" and allows the open. If the user doesn't have
           permission to delete the file this will only be discovered at close
           time, which is too late for the Windows user tools to display an
           error message to the user. The symptom of this is files that appear
           to have been deleted "magically" re-appearing on a Windows explorer
           refersh. This is an extremely advanced protocol option which should
           not need to be changed. This parameter was introduced in its final
           form in 3.0.21, an earlier version with slightly different
           semantics was introduced in 3.0.20. That older version is not
           documented here.

           Default: acl check permissions = True

       acl compatibility (S)

           This parameter specifies what OS ACL semantics should be compatible
           with. Possible values are winnt for Windows NT 4, win2k for Windows
           2000 and above and auto. If you specify auto, the value for this
           parameter will be based upon the version of the client. There
           should be no reason to change this parameter from the default.

           Default: acl compatibility = Auto

           Example: acl compatibility = win2k

       acl group control (S)

           In a POSIX filesystem, only the owner of a file or directory and
           the superuser can modify the permissions and ACLs on a file. If
           this parameter is set, then Samba overrides this restriction, and
           also allows the primary group owner of a file or directory to
           modify the permissions and ACLs on that file.

           On a Windows server, groups may be the owner of a file or directory
           - thus allowing anyone in that group to modify the permissions on
           it. This allows the delegation of security controls on a point in
           the filesystem to the group owner of a directory and anything below
           it also owned by that group. This means there are multiple people
           with permissions to modify ACLs on a file or directory, easing
           managability.

           This parameter allows Samba to also permit delegation of the
           control over a point in the exported directory hierarchy in much
           the same way as Windows. This allows all members of a UNIX group to
           control the permissions on a file or directory they have group
           ownership on.

           This parameter is best used with the inherit owner option and also
           on on a share containing directories with the UNIX setgid bit set
           on them, which causes new files and directories created within it
           to inherit the group ownership from the containing directory.

           This is parameter has been marked deprecated in Samba 3.0.23. The
           same behavior is now implemented by the dos filemode option.

           Default: acl group control = no

       acl map full control (S)

           This boolean parameter controls whether smbd(8)maps a POSIX ACE
           entry of "rwx" (read/write/execute), the maximum allowed POSIX
           permission set, into a Windows ACL of "FULL CONTROL". If this
           parameter is set to true any POSIX ACE entry of "rwx" will be
           returned in a Windows ACL as "FULL CONTROL", is this parameter is
           set to false any POSIX ACE entry of "rwx" will be returned as the
           specific Windows ACL bits representing read, write and execute.

           Default: acl map full control = True

       add group script (G)

           This is the full pathname to a script that will be run AS ROOT by
           smbd(8) when a new group is requested. It will expand any %g to the
           group name passed. This script is only useful for installations
           using the Windows NT domain administration tools. The script is
           free to create a group with an arbitrary name to circumvent unix
           group name restrictions. In that case the script must print the
           numeric gid of the created group on stdout.

           Default: add group script =

           Example: add group script = /usr/sbin/groupadd %g

       add machine script (G)

           This is the full pathname to a script that will be run by smbd(8)
           when a machine is added to Samba's domain and a Unix account
           matching the machine's name appended with a "$" does not already
           exist.

           This option is very similar to the add user script, and likewise
           uses the %u substitution for the account name. Do not use the %m
           substitution.

           Default: add machine script =

           Example: add machine script = /usr/sbin/adduser -n -g machines -c
           Machine -d /var/lib/nobody -s /bin/false %u

       add port command (G)

           Samba 3.0.23 introduced support for adding printer ports remotely
           using the Windows "Add Standard TCP/IP Port Wizard". This option
           defines an external program to be executed when smbd receives a
           request to add a new Port to the system. The script is passed two
           parameters:

           o   port name

           o   device URI

           The deviceURI is in the for of socket://<hostname>[:<portnumber>]
           or lpd://<hostname>/<queuename>.

           Default: add port command =

           Example: add port command = /etc/samba/scripts/addport.sh

       add printer command (G)

           With the introduction of MS-RPC based printing support for Windows
           NT/2000 clients in Samba 2.2, The MS Add Printer Wizard (APW) icon
           is now also available in the "Printers..." folder displayed a share
           listing. The APW allows for printers to be add remotely to a Samba
           or Windows NT/2000 print server.

           For a Samba host this means that the printer must be physically
           added to the underlying printing system. The add printer command
           defines a script to be run which will perform the necessary
           operations for adding the printer to the print system and to add
           the appropriate service definition to the smb.conf file in order
           that it can be shared by smbd(8).

           The addprinter command is automatically invoked with the following
           parameter (in order):

           o   printer name

           o   share name

           o   port name

           o   driver name

           o   location

           o   Windows 9x driver location

           All parameters are filled in from the PRINTER_INFO_2 structure sent
           by the Windows NT/2000 client with one exception. The "Windows 9x
           driver location" parameter is included for backwards compatibility
           only. The remaining fields in the structure are generated from
           answers to the APW questions.

           Once the addprinter command has been executed, smbd will reparse
           the
            smb.conf to determine if the share defined by the APW exists. If
           the sharename is still invalid, then smbd will return an
           ACCESS_DENIED error to the client.

           The "add printer command" program can output a single line of text,
           which Samba will set as the port the new printer is connected to.
           If this line isn't output, Samba won't reload its printer shares.

           Default: add printer command =

           Example: add printer command = /usr/bin/addprinter

       add share command (G)

           Samba 2.2.0 introduced the ability to dynamically add and delete
           shares via the Windows NT 4.0 Server Manager. The add share command
           is used to define an external program or script which will add a
           new service definition to smb.conf. In order to successfully
           execute the add share command, smbd requires that the administrator
           be connected using a root account (i.e. uid == 0).

           If the connected account has SeDiskOperatorPrivilege, scripts
           defined in change share parameter are executed as root.

           When executed, smbd will automatically invoke the add share command
           with five parameters.

           o   configFile - the location of the global smb.conf file.

           o   shareName - the name of the new share.

           o   pathName - path to an **existing** directory on disk.

           o   comment - comment string to associate with the new share.

           o   max connections Number of maximum simultaneous connections to
               this share.

           This parameter is only used for add file shares. To add printer
           shares, see the addprinter command.

           Default: add share command =

           Example: add share command = /usr/local/bin/addshare

       add user script (G)

           This is the full pathname to a script that will be run AS ROOT by
           smbd(8) under special circumstances described below.

           Normally, a Samba server requires that UNIX users are created for
           all users accessing files on this server. For sites that use
           Windows NT account databases as their primary user database
           creating these users and keeping the user list in sync with the
           Windows NT PDC is an onerous task. This option allows smbd to
           create the required UNIX users ON DEMAND when a user accesses the
           Samba server.

           In order to use this option, smbd(8) must NOT be set to security =
           share and add user script must be set to a full pathname for a
           script that will create a UNIX user given one argument of %u, which
           expands into the UNIX user name to create.

           When the Windows user attempts to access the Samba server, at login
           (session setup in the SMB protocol) time, smbd(8) contacts the
           password server and attempts to authenticate the given user with
           the given password. If the authentication succeeds then smbd
           attempts to find a UNIX user in the UNIX password database to map
           the Windows user into. If this lookup fails, and add user script is
           set then smbd will call the specified script AS ROOT, expanding any
           %u argument to be the user name to create.

           If this script successfully creates the user then smbd will
           continue on as though the UNIX user already existed. In this way,
           UNIX users are dynamically created to match existing Windows NT
           accounts.

           See also security, password server, delete user script.

           Default: add user script =

           Example: add user script = /usr/local/samba/bin/add_user %u

       add user to group script (G)

           Full path to the script that will be called when a user is added to
           a group using the Windows NT domain administration tools. It will
           be run by smbd(8) AS ROOT. Any %g will be replaced with the group
           name and any %u will be replaced with the user name.

           Note that the adduser command used in the example below does not
           support the used syntax on all systems.

           Default: add user to group script =

           Example: add user to group script = /usr/sbin/adduser %u %g

       admin users (S)

           This is a list of users who will be granted administrative
           privileges on the share. This means that they will do all file
           operations as the super-user (root).

           You should use this option very carefully, as any user in this list
           will be able to do anything they like on the share, irrespective of
           file permissions.

           This parameter will not work with the security = share in Samba
           3.0. This is by design.

           Default: admin users =

           Example: admin users = jason

       afs share (S)

           This parameter controls whether special AFS features are enabled
           for this share. If enabled, it assumes that the directory exported
           via the path parameter is a local AFS import. The special AFS
           features include the attempt to hand-craft an AFS token if you
           enabled --with-fake-kaserver in configure.

           Default: afs share = no

       afs username map (G)

           If you are using the fake kaserver AFS feature, you might want to
           hand-craft the usernames you are creating tokens for. For example
           this is necessary if you have users from several domain in your AFS
           Protection Database. One possible scheme to code users as
           DOMAIN+User as it is done by winbind with the + as a separator.

           The mapped user name must contain the cell name to log into, so
           without setting this parameter there will be no token.

           Default: afs username map =

           Example: afs username map = %u@afs.samba.org

       aio read size (S)

           If Samba has been built with asynchronous I/O support and this
           integer parameter is set to non-zero value, Samba will read from
           file asynchronously when size of request is bigger than this value.
           Note that it happens only for non-chained and non-chaining reads
           and when not using write cache.

           Current implementation of asynchronous I/O in Samba 3.0 does
           support only up to 10 outstanding asynchronous requests, read and
           write combined.

           Related command: write cache size

           Related command: aio write size

           Default: aio read size = 0

           Example: aio read size = 16384 # Use asynchronous I/O for reads
           bigger than 16KB request size

       aio write size (S)

           If Samba has been built with asynchronous I/O support and this
           integer parameter is set to non-zero value, Samba will write to
           file asynchronously when size of request is bigger than this value.
           Note that it happens only for non-chained and non-chaining reads
           and when not using write cache.

           Current implementation of asynchronous I/O in Samba 3.0 does
           support only up to 10 outstanding asynchronous requests, read and
           write combined.

           Related command: write cache size

           Related command: aio read size

           Default: aio write size = 0

           Example: aio write size = 16384 # Use asynchronous I/O for writes
           bigger than 16KB request size

       algorithmic rid base (G)

           This determines how Samba will use its algorithmic mapping from
           uids/gid to the RIDs needed to construct NT Security Identifiers.

           Setting this option to a larger value could be useful to sites
           transitioning from WinNT and Win2k, as existing user and group rids
           would otherwise clash with sytem users etc.

           All UIDs and GIDs must be able to be resolved into SIDs for the
           correct operation of ACLs on the server. As such the algorithmic
           mapping can't be 'turned off', but pushing it 'out of the way'
           should resolve the issues. Users and groups can then be assigned
           'low' RIDs in arbitrary-rid supporting backends.

           Default: algorithmic rid base = 1000

           Example: algorithmic rid base = 100000

       allocation roundup size (S)

           This parameter allows an administrator to tune the allocation size
           reported to Windows clients. The default size of 1Mb generally
           results in improved Windows client performance. However, rounding
           the allocation size may cause difficulties for some applications,
           e.g. MS Visual Studio. If the MS Visual Studio compiler starts to
           crash with an internal error, set this parameter to zero for this
           share.

           The integer parameter specifies the roundup size in bytes.

           Default: allocation roundup size = 1048576

           Example: allocation roundup size = 0 # (to disable roundups)

       allow trusted domains (G)

           This option only takes effect when the security option is set to
           server, domain or ads. If it is set to no, then attempts to connect
           to a resource from a domain or workgroup other than the one which
           smbd is running in will fail, even if that domain is trusted by the
           remote server doing the authentication.

           This is useful if you only want your Samba server to serve
           resources to users in the domain it is a member of. As an example,
           suppose that there are two domains DOMA and DOMB. DOMB is trusted
           by DOMA, which contains the Samba server. Under normal
           circumstances, a user with an account in DOMB can then access the
           resources of a UNIX account with the same account name on the Samba
           server even if they do not have an account in DOMA. This can make
           implementing a security boundary difficult.

           Default: allow trusted domains = yes

       announce as (G)

           This specifies what type of server nmbd(8) will announce itself as,
           to a network neighborhood browse list. By default this is set to
           Windows NT. The valid options are : "NT Server" (which can also be
           written as "NT"), "NT Workstation", "Win95" or "WfW" meaning
           Windows NT Server, Windows NT Workstation, Windows 95 and Windows
           for Workgroups respectively. Do not change this parameter unless
           you have a specific need to stop Samba appearing as an NT server as
           this may prevent Samba servers from participating as browser
           servers correctly.

           Default: announce as = NT Server

           Example: announce as = Win95

       announce version (G)

           This specifies the major and minor version numbers that nmbd will
           use when announcing itself as a server. The default is 4.9. Do not
           change this parameter unless you have a specific need to set a
           Samba server to be a downlevel server.

           Default: announce version = 4.9

           Example: announce version = 2.0

       auth methods (G)

           This option allows the administrator to chose what authentication
           methods smbd will use when authenticating a user. This option
           defaults to sensible values based on security. This should be
           considered a developer option and used only in rare circumstances.
           In the majority (if not all) of production servers, the default
           setting should be adequate.

           Each entry in the list attempts to authenticate the user in turn,
           until the user authenticates. In practice only one method will ever
           actually be able to complete the authentication.

           Possible options include guest (anonymous access), sam (lookups in
           local list of accounts based on netbios name or domain name),
           winbind (relay authentication requests for remote users through
           winbindd), ntdomain (pre-winbindd method of authentication for
           remote domain users; deprecated in favour of winbind method),
           trustdomain (authenticate trusted users by contacting the remote DC
           directly from smbd; deprecated in favour of winbind method).

           Default: auth methods =

           Example: auth methods = guest sam winbind

       available (S)

           This parameter lets you "turn off" a service. If available = no,
           then ALL attempts to connect to the service will fail. Such
           failures are logged.

           Default: available = yes

       bind interfaces only (G)

           This global parameter allows the Samba admin to limit what
           interfaces on a machine will serve SMB requests. It affects file
           service smbd(8) and name service nmbd(8) in a slightly different
           ways.

           For name service it causes nmbd to bind to ports 137 and 138 on the
           interfaces listed in the interfaces parameter.  nmbd also binds to
           the "all addresses" interface (0.0.0.0) on ports 137 and 138 for
           the purposes of reading broadcast messages. If this option is not
           set then nmbd will service name requests on all of these sockets.
           If bind interfaces only is set then nmbd will check the source
           address of any packets coming in on the broadcast sockets and
           discard any that don't match the broadcast addresses of the
           interfaces in the interfaces parameter list. As unicast packets are
           received on the other sockets it allows nmbd to refuse to serve
           names to machines that send packets that arrive through any
           interfaces not listed in the interfaces list. IP Source address
           spoofing does defeat this simple check, however, so it must not be
           used seriously as a security feature for nmbd.

           For file service it causes smbd(8) to bind only to the interface
           list given in the interfaces parameter. This restricts the networks
           that smbd will serve to packets coming in those interfaces. Note
           that you should not use this parameter for machines that are
           serving PPP or other intermittent or non-broadcast network
           interfaces as it will not cope with non-permanent interfaces.

           If bind interfaces only is set then unless the network address
           127.0.0.1 is added to the interfaces parameter list smbpasswd(8)
           and swat(8) may not work as expected due to the reasons covered
           below.

           To change a users SMB password, the smbpasswd by default connects
           to the localhost - 127.0.0.1 address as an SMB client to issue the
           password change request. If bind interfaces only is set then unless
           the network address 127.0.0.1 is added to the interfaces parameter
           list then smbpasswd will fail to connect in it's default mode.
           smbpasswd can be forced to use the primary IP interface of the
           local host by using its smbpasswd(8) -r remote machine parameter,
           with remote machine set to the IP name of the primary interface of
           the local host.

           The swat status page tries to connect with smbd and nmbd at the
           address 127.0.0.1 to determine if they are running. Not adding
           127.0.0.1 will cause smbd and nmbd to always show "not running"
           even if they really are. This can prevent swat from
           starting/stopping/restarting smbd and nmbd.

           Default: bind interfaces only = no

       blocking locks (S)

           This parameter controls the behavior of smbd(8) when given a
           request by a client to obtain a byte range lock on a region of an
           open file, and the request has a time limit associated with it.

           If this parameter is set and the lock range requested cannot be
           immediately satisfied, samba will internally queue the lock
           request, and periodically attempt to obtain the lock until the
           timeout period expires.

           If this parameter is set to no, then samba will behave as previous
           versions of Samba would and will fail the lock request immediately
           if the lock range cannot be obtained.

           Default: blocking locks = yes

       block size (S)

           This parameter controls the behavior of smbd(8) when reporting disk
           free sizes. By default, this reports a disk block size of 1024
           bytes.

           Changing this parameter may have some effect on the efficiency of
           client writes, this is not yet confirmed. This parameter was added
           to allow advanced administrators to change it (usually to a higher
           value) and test the effect it has on client write performance
           without re-compiling the code. As this is an experimental option it
           may be removed in a future release.

           Changing this option does not change the disk free reporting size,
           just the block size unit reported to the client.

           Default: block size = 1024

           Example: block size = 4096
       browsable.PP
           This parameter is a synonym for browseable.

       browseable (S)

           This controls whether this share is seen in the list of available
           shares in a net view and in the browse list.

           Default: browseable = yes

       browse list (G)

           This controls whether smbd(8) will serve a browse list to a client
           doing a NetServerEnum call. Normally set to yes. You should never
           need to change this.

           Default: browse list = yes
       casesignames.PP
           This parameter is a synonym for case sensitive.

       case sensitive (S)

           See the discussion in the section name mangling.

           Default: case sensitive = no

       change notify (S)

           This parameter specifies whether Samba should reply to a client's
           file change notify requests.

           You should never need to change this parameter

           Default: change notify = yes

       change share command (G)

           Samba 2.2.0 introduced the ability to dynamically add and delete
           shares via the Windows NT 4.0 Server Manager. The change share
           command is used to define an external program or script which will
           modify an existing service definition in smb.conf. In order to
           successfully execute the change share command, smbd requires that
           the administrator be connected using a root account (i.e. uid ==
           0).

           If the connected account has SeDiskOperatorPrivilege, scripts
           defined in change share parameter are executed as root.

           When executed, smbd will automatically invoke the change share
           command with five parameters.

           o   configFile - the location of the global smb.conf file.

           o   shareName - the name of the new share.

           o   pathName - path to an **existing** directory on disk.

           o   comment - comment string to associate with the new share.

           o   max connections Number of maximum simultaneous connections to
               this share.

           This parameter is only used modify existing file shares
           definitions. To modify printer shares, use the "Printers..." folder
           as seen when browsing the Samba host.

           Default: change share command =

           Example: change share command = /usr/local/bin/addshare

       check password script (G)

           The name of a program that can be used to check password
           complexity. The password is sent to the program's standrad input.

           The program must return 0 on good password any other value
           otherwise. In case the password is considered weak (the program do
           not return 0) the user will be notified and the password change
           will fail.

           Note: In the example directory there is a sample program called
           crackcheck that uses cracklib to checkpassword quality.

           Default: check password script = Disabled

           Example: check password script = check password script =
           /usr/local/sbin/crackcheck

       client lanman auth (G)

           This parameter determines whether or not smbclient(8) and other
           samba client tools will attempt to authenticate itself to servers
           using the weaker LANMAN password hash. If disabled, only server
           which support NT password hashes (e.g. Windows NT/2000, Samba,
           etc... but not Windows 95/98) will be able to be connected from the
           Samba client.

           The LANMAN encrypted response is easily broken, due to it's
           case-insensitive nature, and the choice of algorithm. Clients
           without Windows 95/98 servers are advised to disable this option.

           Disabling this option will also disable the client plaintext auth
           option

           Likewise, if the client ntlmv2 auth parameter is enabled, then only
           NTLMv2 logins will be attempted.

           Default: client lanman auth = yes

       client ntlmv2 auth (G)

           This parameter determines whether or not smbclient(8) will attempt
           to authenticate itself to servers using the NTLMv2 encrypted
           password response.

           If enabled, only an NTLMv2 and LMv2 response (both much more secure
           than earlier versions) will be sent. Many servers (including NT4 <
           SP4, Win9x and Samba 2.2) are not compatible with NTLMv2.

           Similarly, if enabled, NTLMv1, client lanman auth and client
           plaintext auth authentication will be disabled. This also disables
           share-level authentication.

           If disabled, an NTLM response (and possibly a LANMAN response) will
           be sent by the client, depending on the value of client lanman
           auth.

           Note that some sites (particularly those following 'best practice'
           security polices) only allow NTLMv2 responses, and not the weaker
           LM or NTLM.

           Default: client ntlmv2 auth = no

       client plaintext auth (G)

           Specifies whether a client should send a plaintext password if the
           server does not support encrypted passwords.

           Default: client plaintext auth = yes

       client schannel (G)

           This controls whether the client offers or even demands the use of
           the netlogon schannel.  client schannel = no does not offer the
           schannel, client schannel = auto offers the schannel but does not
           enforce it, and client schannel = yes denies access if the server
           is not able to speak netlogon schannel.

           Default: client schannel = auto

           Example: client schannel = yes

       client signing (G)

           This controls whether the client offers or requires the server it
           talks to to use SMB signing. Possible values are auto, mandatory
           and disabled.

           When set to auto, SMB signing is offered, but not enforced. When
           set to mandatory, SMB signing is required and if set to disabled,
           SMB signing is not offered either.

           Default: client signing = auto

       client use spnego (G)

           This variable controls whether Samba clients will try to use Simple
           and Protected NEGOciation (as specified by rfc2478) with supporting
           servers (including WindowsXP, Windows2000 and Samba 3.0) to agree
           upon an authentication mechanism. This enables Kerberos
           authentication in particular.

           Default: client use spnego = yes

       comment (S)

           This is a text field that is seen next to a share when a client
           does a queries the server, either via the network neighborhood or
           via smbnet view to list what shares are available.

           If you want to set the string that is displayed next to the machine
           name then see the server string parameter.

           Default: comment =  # No comment

           Example: comment = Fred's Files

       config file (G)

           This allows you to override the config file to use, instead of the
           default (usually smb.conf). There is a chicken and egg problem here
           as this option is set in the config file!

           For this reason, if the name of the config file has changed when
           the parameters are loaded then it will reload them from the new
           config file.

           This option takes the usual substitutions, which can be very
           useful.

           If the config file doesn't exist then it won't be loaded (allowing
           you to special case the config files of just a few clients).

           No default

           Example: config file = /usr/local/samba/lib/smb.conf.%m

       copy (S)

           This parameter allows you to "clone" service entries. The specified
           service is simply duplicated under the current service's name. Any
           parameters specified in the current section will override those in
           the section being copied.

           This feature lets you set up a 'template' service and create
           similar services easily. Note that the service being copied must
           occur earlier in the configuration file than the service doing the
           copying.

           Default: copy =

           Example: copy = otherservice
       create mode.PP
           This parameter is a synonym for create mask.

       create mask (S)

           When a file is created, the necessary permissions are calculated
           according to the mapping from DOS modes to UNIX permissions, and
           the resulting UNIX mode is then bit-wise 'AND'ed with this
           parameter. This parameter may be thought of as a bit-wise MASK for
           the UNIX modes of a file. Any bit not set here will be removed from
           the modes set on a file when it is created.

           The default value of this parameter removes the group and other
           write and execute bits from the UNIX modes.

           Following this Samba will bit-wise 'OR' the UNIX mode created from
           this parameter with the value of the force create mode parameter
           which is set to 000 by default.

           This parameter does not affect directory masks. See the parameter
           directory mask for details.

           Note that this parameter does not apply to permissions set by
           Windows NT/2000 ACL editors. If the administrator wishes to enforce
           a mask on access control lists also, they need to set the security
           mask.

           Default: create mask = 0744

           Example: create mask = 0775

       csc policy (S)

           This stands for client-side caching policy, and specifies how
           clients capable of offline caching will cache the files in the
           share. The valid values are: manual, documents, programs, disable.

           These values correspond to those used on Windows servers.

           For example, shares containing roaming profiles can have offline
           caching disabled using csc policy = disable.

           Default: csc policy = manual

           Example: csc policy = programs

       cups options (S)

           This parameter is only applicable if printing is set to cups. Its
           value is a free form string of options passed directly to the cups
           library.

           You can pass any generic print option known to CUPS (as listed in
           the CUPS "Software Users' Manual"). You can also pass any printer
           specific option (as listed in "lpoptions -d printername -l") valid
           for the target queue. Multiple parameters should be space-delimited
           name/value pairs according to the PAPI text option ABNF
           specification. Collection values ("name={a=... b=... c=...}") are
           stored with the curley brackets intact.

           You should set this parameter to raw if your CUPS server error_log
           file contains messages such as "Unsupported format
           'application/octet-stream'" when printing from a Windows client
           through Samba. It is no longer necessary to enable system wide raw
           printing in /etc/cups/mime.{convs,types}.

           Default: cups options = ""

           Example: cups options = "raw media=a4"

       cups server (G)

           This parameter is only applicable if printing is set to cups.

           If set, this option overrides the ServerName option in the CUPS
           client.conf. This is necessary if you have virtual samba servers
           that connect to different CUPS daemons.

           Optionally, a port can be specified by separating the server name
           and port number with a colon. If no port was specified, the default
           port for IPP (631) will be used.

           Default: cups server = ""

           Example: cups server = mycupsserver

           Example: cups server = mycupsserver:1631

       deadtime (G)

           The value of the parameter (a decimal integer) represents the
           number of minutes of inactivity before a connection is considered
           dead, and it is disconnected. The deadtime only takes effect if the
           number of open files is zero.

           This is useful to stop a server's resources being exhausted by a
           large number of inactive connections.

           Most clients have an auto-reconnect feature when a connection is
           broken so in most cases this parameter should be transparent to
           users.

           Using this parameter with a timeout of a few minutes is recommended
           for most systems.

           A deadtime of zero indicates that no auto-disconnection should be
           performed.

           Default: deadtime = 0

           Example: deadtime = 15

       debug hires timestamp (G)

           Sometimes the timestamps in the log messages are needed with a
           resolution of higher that seconds, this boolean parameter adds
           microsecond resolution to the timestamp message header when turned
           on.

           Note that the parameter debug timestamp must be on for this to have
           an effect.

           Default: debug hires timestamp = no

       debug pid (G)

           When using only one log file for more then one forked
           smbd(8)-process there may be hard to follow which process outputs
           which message. This boolean parameter is adds the process-id to the
           timestamp message headers in the logfile when turned on.

           Note that the parameter debug timestamp must be on for this to have
           an effect.

           Default: debug pid = no

       debug prefix timestamp (G)

           With this option enabled, the timestamp message header is prefixed
           to the debug message without the filename and function information
           that is included with the debug timestamp parameter. This gives
           timestamps to the messages without adding an additional line.

           Note that this parameter overrides the debug timestamp parameter.

           Default: debug prefix timestamp = no
       timestamp logs.PP
           This parameter is a synonym for debug timestamp.

       debug timestamp (G)

           Samba debug log messages are timestamped by default. If you are
           running at a high debug level these timestamps can be distracting.
           This boolean parameter allows timestamping to be turned off.

           Default: debug timestamp = yes

       debug uid (G)

           Samba is sometimes run as root and sometime run as the connected
           user, this boolean parameter inserts the current euid, egid, uid
           and gid to the timestamp message headers in the log file if turned
           on.

           Note that the parameter debug timestamp must be on for this to have
           an effect.

           Default: debug uid = no

       default case (S)

           See the section on name mangling. Also note the short preserve case
           parameter.

           Default: default case = lower

       default devmode (S)

           This parameter is only applicable to printable services. When smbd
           is serving Printer Drivers to Windows NT/2k/XP clients, each
           printer on the Samba server has a Device Mode which defines things
           such as paper size and orientation and duplex settings. The device
           mode can only correctly be generated by the printer driver itself
           (which can only be executed on a Win32 platform). Because smbd is
           unable to execute the driver code to generate the device mode, the
           default behavior is to set this field to NULL.

           Most problems with serving printer drivers to Windows NT/2k/XP
           clients can be traced to a problem with the generated device mode.
           Certain drivers will do things such as crashing the client's
           Explorer.exe with a NULL devmode. However, other printer drivers
           can cause the client's spooler service (spoolsv.exe) to die if the
           devmode was not created by the driver itself (i.e. smbd generates a
           default devmode).

           This parameter should be used with care and tested with the printer
           driver in question. It is better to leave the device mode to NULL
           and let the Windows client set the correct values. Because drivers
           do not do this all the time, setting default devmode = yes will
           instruct smbd to generate a default one.

           For more information on Windows NT/2k printing and Device Modes,
           see the MSDN documentation.

           Default: default devmode = yes
       default.PP
           This parameter is a synonym for default service.

       default service (G)

           This parameter specifies the name of a service which will be
           connected to if the service actually requested cannot be found.
           Note that the square brackets are NOT given in the parameter value
           (see example below).

           There is no default value for this parameter. If this parameter is
           not given, attempting to connect to a nonexistent service results
           in an error.

           Typically the default service would be a guest ok, read-only
           service.

           Also note that the apparent service name will be changed to equal
           that of the requested service, this is very useful as it allows you
           to use macros like %S to make a wildcard service.

           Note also that any "_" characters in the name of the service used
           in the default service will get mapped to a "/". This allows for
           interesting things.

           Default: default service =

           Example: default service = pub

       defer sharing violations (G)

           Windows allows specifying how a file will be shared with other
           processes when it is opened. Sharing violations occur when a file
           is opened by a different process using options that violate the
           share settings specified by other processes. This parameter causes
           smbd to act as a Windows server does, and defer returning a
           "sharing violation" error message for up to one second, allowing
           the client to close the file causing the violation in the meantime.

           UNIX by default does not have this behaviour.

           There should be no reason to turn off this parameter, as it is
           designed to enable Samba to more correctly emulate Windows.

           Default: defer sharing violations = True

       delete group script (G)

           This is the full pathname to a script that will be run AS ROOT
           smbd(8) when a group is requested to be deleted. It will expand any
           %g to the group name passed. This script is only useful for
           installations using the Windows NT domain administration tools.

           Default: delete group script =

       deleteprinter command (G)

           With the introduction of MS-RPC based printer support for Windows
           NT/2000 clients in Samba 2.2, it is now possible to delete printer
           at run time by issuing the DeletePrinter() RPC call.

           For a Samba host this means that the printer must be physically
           deleted from underlying printing system. The deleteprinter command
           defines a script to be run which will perform the necessary
           operations for removing the printer from the print system and from
           smb.conf.

           The deleteprinter command is automatically called with only one
           parameter: printer name.

           Once the deleteprinter command has been executed, smbd will reparse
           the
            smb.conf to associated printer no longer exists. If the sharename
           is still valid, then smbd will return an ACCESS_DENIED error to the
           client.

           Default: deleteprinter command =

           Example: deleteprinter command = /usr/bin/removeprinter

       delete readonly (S)

           This parameter allows readonly files to be deleted. This is not
           normal DOS semantics, but is allowed by UNIX.

           This option may be useful for running applications such as rcs,
           where UNIX file ownership prevents changing file permissions, and
           DOS semantics prevent deletion of a read only file.

           Default: delete readonly = no

       delete share command (G)

           Samba 2.2.0 introduced the ability to dynamically add and delete
           shares via the Windows NT 4.0 Server Manager. The delete share
           command is used to define an external program or script which will
           remove an existing service definition from smb.conf. In order to
           successfully execute the delete share command, smbd requires that
           the administrator be connected using a root account (i.e. uid ==
           0).

           If the connected account has SeDiskOperatorPrivilege, scripts
           defined in change share parameter are executed as root.

           When executed, smbd will automatically invoke the delete share
           command with two parameters.

           o   configFile - the location of the global smb.conf file.

           o   shareName - the name of the existing service.

           This parameter is only used to remove file shares. To delete
           printer shares, see the deleteprinter command.

           Default: delete share command =

           Example: delete share command = /usr/local/bin/delshare

       delete user from group script (G)

           Full path to the script that will be called when a user is removed
           from a group using the Windows NT domain administration tools. It
           will be run by smbd(8) AS ROOT. Any %g will be replaced with the
           group name and any %u will be replaced with the user name.

           Default: delete user from group script =

           Example: delete user from group script = /usr/sbin/deluser %u %g

       delete user script (G)

           This is the full pathname to a script that will be run by smbd(8)
           when managing users with remote RPC (NT) tools.

           This script is called when a remote client removes a user from the
           server, normally using 'User Manager for Domains' or rpcclient.

           This script should delete the given UNIX username.

           Default: delete user script =

           Example: delete user script = /usr/local/samba/bin/del_user %u

       delete veto files (S)

           This option is used when Samba is attempting to delete a directory
           that contains one or more vetoed directories (see the veto files
           option). If this option is set to no (the default) then if a vetoed
           directory contains any non-vetoed files or directories then the
           directory delete will fail. This is usually what you want.

           If this option is set to yes, then Samba will attempt to
           recursively delete any files and directories within the vetoed
           directory. This can be useful for integration with file serving
           systems such as NetAtalk which create meta-files within directories
           you might normally veto DOS/Windows users from seeing (e.g.
           .AppleDouble)

           Setting delete veto files = yes allows these directories to be
           transparently deleted when the parent directory is deleted (so long
           as the user has permissions to do so).

           Default: delete veto files = no

       dfree cache time (S)

           The dfree cache time should only be used on systems where a problem
           occurs with the internal disk space calculations. This has been
           known to happen with Ultrix, but may occur with other operating
           systems. The symptom that was seen was an error of "Abort Retry
           Ignore" at the end of each directory listing.

           This is a new parameter introduced in Samba version 3.0.21. It
           specifies in seconds the time that smbd will cache the output of a
           disk free query. If set to zero (the default) no caching is done.
           This allows a heavily loaded server to prevent rapid spawning of
           dfree command scripts increasing the load.

           By default this parameter is zero, meaning no caching will be done.

           No default

           Example: dfree cache time = dfree cache time = 60

       dfree command (S)

           The dfree command setting should only be used on systems where a
           problem occurs with the internal disk space calculations. This has
           been known to happen with Ultrix, but may occur with other
           operating systems. The symptom that was seen was an error of "Abort
           Retry Ignore" at the end of each directory listing.

           This setting allows the replacement of the internal routines to
           calculate the total disk space and amount available with an
           external routine. The example below gives a possible script that
           might fulfill this function.

           In Samba version 3.0.21 this parameter has been changed to be a
           per-share parameter, and in addition the parameter dfree cache time
           was added to allow the output of this script to be cached for
           systems under heavy load.

           The external program will be passed a single parameter indicating a
           directory in the filesystem being queried. This will typically
           consist of the string ./. The script should return two integers in
           ASCII. The first should be the total disk space in blocks, and the
           second should be the number of available blocks. An optional third
           return value can give the block size in bytes. The default
           blocksize is 1024 bytes.

           Note: Your script should NOT be setuid or setgid and should be
           owned by (and writeable only by) root!

           Where the script dfree (which must be made executable) could be:

               #!/bin/sh
               df $1 | tail -1 | awk '{print $(NF-4),$(NF-2)}'

           or perhaps (on Sys V based systems):

               #!/bin/sh
               /usr/bin/df -k $1 | tail -1 | awk '{print $3" "$5}'

           Note that you may have to replace the command names with full path
           names on some systems.

           By default internal routines for determining the disk capacity and
           remaining space will be used.

           No default

           Example: dfree command = /usr/local/samba/bin/dfree
       directory mode.PP
           This parameter is a synonym for directory mask.

       directory mask (S)

           This parameter is the octal modes which are used when converting
           DOS modes to UNIX modes when creating UNIX directories.

           When a directory is created, the necessary permissions are
           calculated according to the mapping from DOS modes to UNIX
           permissions, and the resulting UNIX mode is then bit-wise 'AND'ed
           with this parameter. This parameter may be thought of as a bit-wise
           MASK for the UNIX modes of a directory. Any bit not set here will
           be removed from the modes set on a directory when it is created.

           The default value of this parameter removes the 'group' and 'other'
           write bits from the UNIX mode, allowing only the user who owns the
           directory to modify it.

           Following this Samba will bit-wise 'OR' the UNIX mode created from
           this parameter with the value of the force directory mode
           parameter. This parameter is set to 000 by default (i.e. no extra
           mode bits are added).

           Note that this parameter does not apply to permissions set by
           Windows NT/2000 ACL editors. If the administrator wishes to enforce
           a mask on access control lists also, they need to set the directory
           security mask.

           Default: directory mask = 0755

           Example: directory mask = 0775

       directory security mask (S)

           This parameter controls what UNIX permission bits will be set when
           a Windows NT client is manipulating the UNIX permission on a
           directory using the native NT security dialog box.

           This parameter is applied as a mask (AND'ed with) to the incoming
           permission bits, thus resetting any bits not in this mask. Make
           sure not to mix up this parameter with force directory security
           mode, which works similar like this one but uses logical OR instead
           of AND. Essentially, zero bits in this mask are a set of bits that
           will always be set to zero.

           Essentially, all bits set to zero in this mask will result in
           setting to zero the corresponding bits on the file permissions
           regardless of the previous status of this bits on the file.

           If not set explicitly this parameter is set to 0777 meaning a user
           is allowed to set all the user/group/world permissions on a
           directory.

           Note that users who can access the Samba server through other means
           can easily bypass this restriction, so it is primarily useful for
           standalone "appliance" systems. Administrators of most normal
           systems will probably want to leave it as the default of 0777.

           Default: directory security mask = 0777

           Example: directory security mask = 0700

       disable netbios (G)

           Enabling this parameter will disable netbios support in Samba.
           Netbios is the only available form of browsing in all windows
           versions except for 2000 and XP.

           Note
           Clients that only support netbios won't be able to see your samba
           server when netbios support is disabled.

           Default: disable netbios = no

       disable spoolss (G)

           Enabling this parameter will disable Samba's support for the
           SPOOLSS set of MS-RPC's and will yield identical behavior as Samba
           2.0.x. Windows NT/2000 clients will downgrade to using Lanman style
           printing commands. Windows 9x/ME will be unaffected by the
           parameter. However, this will also disable the ability to upload
           printer drivers to a Samba server via the Windows NT Add Printer
           Wizard or by using the NT printer properties dialog window. It will
           also disable the capability of Windows NT/2000 clients to download
           print drivers from the Samba host upon demand.  Be very careful
           about enabling this parameter.

           Default: disable spoolss = no

       display charset (G)

           Specifies the charset that samba will use to print messages to
           stdout and stderr. The default value is "LOCALE", which means
           automatically set, depending on the current locale. The value
           should generally be the same as the value of the parameter unix
           charset.

           Default: display charset = "LOCALE" or "ASCII" (depending on the
           system)

           Example: display charset = UTF8

       dmapi support (S)

           This parameter specifies whether Samba should use DMAPI to
           determine whether a file is offline or not. This would typically be
           used in conjunction with a hierarchical storage system that
           automatically migrates files to tape.

           Note that Samba infers the status of a file by examining the events
           that a DMAPI application has registered interest in. This heuristic
           is satisfactory for a number of hierarchical storage systems, but
           there may be system for which it will fail. In this case, Samba may
           erroneously report files to be offline.

           This parameter is only available if a supported DMAPI
           implementation was found at compilation time. It will only be used
           if DMAPI is found to enabled on the system at run time.

           Default: dmapi support = no

       dns proxy (G)

           Specifies that nmbd(8) when acting as a WINS server and finding
           that a NetBIOS name has not been registered, should treat the
           NetBIOS name word-for-word as a DNS name and do a lookup with the
           DNS server for that name on behalf of the name-querying client.

           Note that the maximum length for a NetBIOS name is 15 characters,
           so the DNS name (or DNS alias) can likewise only be 15 characters,
           maximum.

           nmbd spawns a second copy of itself to do the DNS name lookup
           requests, as doing a name lookup is a blocking action.

           Default: dns proxy = yes

       domain logons (G)

           If set to yes, the Samba server will provide the netlogon service
           for Windows 9X network logons for the workgroup it is in. This will
           also cause the Samba server to act as a domain controller for NT4
           style domain services. For more details on setting up this feature
           see the Domain Control chapter of the Samba HOWTO Collection.

           Default: domain logons = no

       domain master (G)

           Tell smbd(8) to enable WAN-wide browse list collation. Setting this
           option causes nmbd to claim a special domain specific NetBIOS name
           that identifies it as a domain master browser for its given
           workgroup. Local master browsers in the same workgroup on
           broadcast-isolated subnets will give this nmbd their local browse
           lists, and then ask smbd(8) for a complete copy of the browse list
           for the whole wide area network. Browser clients will then contact
           their local master browser, and will receive the domain-wide browse
           list, instead of just the list for their broadcast-isolated subnet.

           Note that Windows NT Primary Domain Controllers expect to be able
           to claim this workgroup specific special NetBIOS name that
           identifies them as domain master browsers for that workgroup by
           default (i.e. there is no way to prevent a Windows NT PDC from
           attempting to do this). This means that if this parameter is set
           and nmbd claims the special name for a workgroup before a Windows
           NT PDC is able to do so then cross subnet browsing will behave
           strangely and may fail.

           If domain logons = yes, then the default behavior is to enable the
           domain master parameter. If domain logons is not enabled (the
           default setting), then neither will domain master be enabled by
           default.

           When domain logons = Yes the default setting for this parameter is
           Yes, with the result that Samba will be a PDC. If domain master =
           No, Samba will function as a BDC. In general, this parameter should
           be set to 'No' only on a BDC.

           Default: domain master = auto

       dont descend (S)

           There are certain directories on some systems (e.g., the /proc tree
           under Linux) that are either not of interest to clients or are
           infinitely deep (recursive). This parameter allows you to specify a
           comma-delimited list of directories that the server should always
           show as empty.

           Note that Samba can be very fussy about the exact format of the
           "dont descend" entries. For example you may need
            ./proc instead of just /proc. Experimentation is the best policy
           :-)

           Default: dont descend =

           Example: dont descend = /proc,/dev

       dos charset (G)

           DOS SMB clients assume the server has the same charset as they do.
           This option specifies which charset Samba should talk to DOS
           clients.

           The default depends on which charsets you have installed. Samba
           tries to use charset 850 but falls back to ASCII in case it is not
           available. Run testparm(1) to check the default on your system.

           No default

       dos filemode (S)

           The default behavior in Samba is to provide UNIX-like behavior
           where only the owner of a file/directory is able to change the
           permissions on it. However, this behavior is often confusing to
           DOS/Windows users. Enabling this parameter allows a user who has
           write access to the file (by whatever means) to modify the
           permissions (including ACL) on it. Note that a user belonging to
           the group owning the file will not be allowed to change permissions
           if the group is only granted read access. Ownership of the
           file/directory may also be changed.

           Default: dos filemode = no

       dos filetime resolution (S)

           Under the DOS and Windows FAT filesystem, the finest granularity on
           time resolution is two seconds. Setting this parameter for a share
           causes Samba to round the reported time down to the nearest two
           second boundary when a query call that requires one second
           resolution is made to smbd(8).

           This option is mainly used as a compatibility option for Visual C++
           when used against Samba shares. If oplocks are enabled on a share,
           Visual C++ uses two different time reading calls to check if a file
           has changed since it was last read. One of these calls uses a
           one-second granularity, the other uses a two second granularity. As
           the two second call rounds any odd second down, then if the file
           has a timestamp of an odd number of seconds then the two timestamps
           will not match and Visual C++ will keep reporting the file has
           changed. Setting this option causes the two timestamps to match,
           and Visual C++ is happy.

           Default: dos filetime resolution = no

       dos filetimes (S)

           Under DOS and Windows, if a user can write to a file they can
           change the timestamp on it. Under POSIX semantics, only the owner
           of the file or root may change the timestamp. By default, Samba
           runs with POSIX semantics and refuses to change the timestamp on a
           file if the user smbd is acting on behalf of is not the file owner.
           Setting this option to
            yes allows DOS semantics and smbd(8) will change the file
           timestamp as DOS requires. Due to changes in Microsoft Office 2000
           and beyond, the default for this parameter has been changed from
           "no" to "yes" in Samba 3.0.14 and above. Microsoft Excel will
           display dialog box warnings about the file being changed by another
           user if this parameter is not set to "yes" and files are being
           shared between users.

           Default: dos filetimes = yes

       ea support (S)

           This boolean parameter controls whether smbd(8) will allow clients
           to attempt to store OS/2 style Extended attributes on a share. In
           order to enable this parameter the underlying filesystem exported
           by the share must support extended attributes (such as provided on
           XFS and EXT3 on Linux, with the correct kernel patches). On Linux
           the filesystem must have been mounted with the mount option
           user_xattr in order for extended attributes to work, also extended
           attributes must be compiled into the Linux kernel.

           Default: ea support = no

       enable asu support (G)

           Hosts running the "Advanced Server for Unix (ASU)" product require
           some special accomodations such as creating a builting [ADMIN$]
           share that only supports IPC connections. The has been the default
           behavior in smbd for many years. However, certain Microsoft
           applications such as the Print Migrator tool require that the
           remote server support an [ADMIN$} file share. Disabling this
           parameter allows for creating an [ADMIN$] file share in smb.conf.

           Default: enable asu support = no

       enable privileges (G)

           This parameter controls whether or not smbd will honor privileges
           assigned to specific SIDs via either smbnet rpc rights or one of
           the Windows user and group manager tools. This parameter is enabled
           by default. It can be disabled to prevent members of the Domain
           Admins group from being able to assign privileges to users or
           groups which can then result in certain smbd operations running as
           root that would normally run under the context of the connected
           user.

           An example of how privileges can be used is to assign the right to
           join clients to a Samba controlled domain without providing root
           access to the server via smbd.

           Please read the extended description provided in the Samba HOWTO
           documentation.

           Default: enable privileges = yes

       encrypt passwords (G)

           This boolean controls whether encrypted passwords will be
           negotiated with the client. Note that Windows NT 4.0 SP3 and above
           and also Windows 98 will by default expect encrypted passwords
           unless a registry entry is changed. To use encrypted passwords in
           Samba see the chapter "User Database" in the Samba HOWTO
           Collection.

           MS Windows clients that expect Microsoft encrypted passwords and
           that do not have plain text password support enabled will be able
           to connect only to a Samba server that has encrypted password
           support enabled and for which the user accounts have a valid
           encrypted password. Refer to the smbpasswd command man page for
           information regarding the creation of encrypted passwords for user
           accounts.

           The use of plain text passwords is NOT advised as support for this
           feature is no longer maintained in Microsoft Windows products. If
           you want to use plain text passwords you must set this parameter to
           no.

           In order for encrypted passwords to work correctly smbd(8) must
           either have access to a local smbpasswd(5) file (see the
           smbpasswd(8) program for information on how to set up and maintain
           this file), or set the security = [server|domain|ads] parameter
           which causes smbd to authenticate against another server.

           Default: encrypt passwords = yes

       enhanced browsing (G)

           This option enables a couple of enhancements to cross-subnet browse
           propagation that have been added in Samba but which are not
           standard in Microsoft implementations.

           The first enhancement to browse propagation consists of a regular
           wildcard query to a Samba WINS server for all Domain Master
           Browsers, followed by a browse synchronization with each of the
           returned DMBs. The second enhancement consists of a regular
           randomised browse synchronization with all currently known DMBs.

           You may wish to disable this option if you have a problem with
           empty workgroups not disappearing from browse lists. Due to the
           restrictions of the browse protocols these enhancements can cause a
           empty workgroup to stay around forever which can be annoying.

           In general you should leave this option enabled as it makes
           cross-subnet browse propagation much more reliable.

           Default: enhanced browsing = yes

       enumports command (G)

           The concept of a "port" is fairly foreign to UNIX hosts. Under
           Windows NT/2000 print servers, a port is associated with a port
           monitor and generally takes the form of a local port (i.e. LPT1:,
           COM1:, FILE:) or a remote port (i.e. LPD Port Monitor, etc...). By
           default, Samba has only one port defined--"Samba Printer Port".
           Under Windows NT/2000, all printers must have a valid port name. If
           you wish to have a list of ports displayed (smbd does not use a
           port name for anything) other than the default "Samba Printer
           Port", you can define enumports command to point to a program which
           should generate a list of ports, one per line, to standard output.
           This listing will then be used in response to the level 1 and 2
           EnumPorts() RPC.

           Default: enumports command =

           Example: enumports command = /usr/bin/listports

       eventlog list (G)

           This option defines a list of log names that Samba will report to
           the Microsoft EventViewer utility. The listed eventlogs will be
           associated with tdb file on disk in the $(lockdir)/eventlog.

           The administrator must use an external process to parse the normal
           Unix logs such as /var/log/messages and write then entries to the
           eventlog tdb files. Refer to the eventlogadm(8) utility for how to
           write eventlog entries.

           Default: eventlog list =

           Example: eventlog list = Security Application Syslog Apache

       fake directory create times (S)

           NTFS and Windows VFAT file systems keep a create time for all files
           and directories. This is not the same as the ctime - status change
           time - that Unix keeps, so Samba by default reports the earliest of
           the various times Unix does keep. Setting this parameter for a
           share causes Samba to always report midnight 1-1-1980 as the create
           time for directories.

           This option is mainly used as a compatibility option for Visual C++
           when used against Samba shares. Visual C++ generated makefiles have
           the object directory as a dependency for each object file, and a
           make rule to create the directory. Also, when NMAKE compares
           timestamps it uses the creation time when examining a directory.
           Thus the object directory will be created if it does not exist, but
           once it does exist it will always have an earlier timestamp than
           the object files it contains.

           However, Unix time semantics mean that the create time reported by
           Samba will be updated whenever a file is created or or deleted in
           the directory. NMAKE finds all object files in the object
           directory. The timestamp of the last one built is then compared to
           the timestamp of the object directory. If the directory's timestamp
           if newer, then all object files will be rebuilt. Enabling this
           option ensures directories always predate their contents and an
           NMAKE build will proceed as expected.

           Default: fake directory create times = no

       fake oplocks (S)

           Oplocks are the way that SMB clients get permission from a server
           to locally cache file operations. If a server grants an oplock
           (opportunistic lock) then the client is free to assume that it is
           the only one accessing the file and it will aggressively cache file
           data. With some oplock types the client may even cache file
           open/close operations. This can give enormous performance benefits.

           When you set fake oplocks = yes, smbd(8) will always grant oplock
           requests no matter how many clients are using the file.

           It is generally much better to use the real oplocks support rather
           than this parameter.

           If you enable this option on all read-only shares or shares that
           you know will only be accessed from one client at a time such as
           physically read-only media like CDROMs, you will see a big
           performance improvement on many operations. If you enable this
           option on shares where multiple clients may be accessing the files
           read-write at the same time you can get data corruption. Use this
           option carefully!

           Default: fake oplocks = no

       follow symlinks (S)

           This parameter allows the Samba administrator to stop smbd(8) from
           following symbolic links in a particular share. Setting this
           parameter to no prevents any file or directory that is a symbolic
           link from being followed (the user will get an error). This option
           is very useful to stop users from adding a symbolic link to
           /etc/passwd in their home directory for instance. However it will
           slow filename lookups down slightly.

           This option is enabled (i.e.  smbd will follow symbolic links) by
           default.

           Default: follow symlinks = yes

       force create mode (S)

           This parameter specifies a set of UNIX mode bit permissions that
           will always be set on a file created by Samba. This is done by
           bitwise 'OR'ing these bits onto the mode bits of a file that is
           being created or having its permissions changed. The default for
           this parameter is (in octal) 000. The modes in this parameter are
           bitwise 'OR'ed onto the file mode after the mask set in the create
           mask parameter is applied.

           The example below would force all created files to have read and
           execute permissions set for 'group' and 'other' as well as the
           read/write/execute bits set for the 'user'.

           Default: force create mode = 000

           Example: force create mode = 0755

       force directory mode (S)

           This parameter specifies a set of UNIX mode bit permissions that
           will always be set on a directory created by Samba. This is done by
           bitwise 'OR'ing these bits onto the mode bits of a directory that
           is being created. The default for this parameter is (in octal) 0000
           which will not add any extra permission bits to a created
           directory. This operation is done after the mode mask in the
           parameter directory mask is applied.

           The example below would force all created directories to have read
           and execute permissions set for 'group' and 'other' as well as the
           read/write/execute bits set for the 'user'.

           Default: force directory mode = 000

           Example: force directory mode = 0755

       force directory security mode (S)

           This parameter controls what UNIX permission bits can be modified
           when a Windows NT client is manipulating the UNIX permission on a
           directory using the native NT security dialog box.

           This parameter is applied as a mask (OR'ed with) to the changed
           permission bits, thus forcing any bits in this mask that the user
           may have modified to be on. Make sure not to mix up this parameter
           with directory security mask, which works in a similar manner to
           this one, but uses a logical AND instead of an OR.

           Essentially, this mask may be treated as a set of bits that, when
           modifying security on a directory, to will enable (1) any flags
           that are off (0) but which the mask has set to on (1).

           If not set explicitly this parameter is 0000, which allows a user
           to modify all the user/group/world permissions on a directory
           without restrictions.

           Note
           Users who can access the Samba server through other means can
           easily bypass this restriction, so it is primarily useful for
           standalone "appliance" systems. Administrators of most normal
           systems will probably want to leave it set as 0000.

           Default: force directory security mode = 0

           Example: force directory security mode = 700
       group.PP
           This parameter is a synonym for force group.

       force group (S)

           This specifies a UNIX group name that will be assigned as the
           default primary group for all users connecting to this service.
           This is useful for sharing files by ensuring that all access to
           files on service will use the named group for their permissions
           checking. Thus, by assigning permissions for this group to the
           files and directories within this service the Samba administrator
           can restrict or allow sharing of these files.

           In Samba 2.0.5 and above this parameter has extended functionality
           in the following way. If the group name listed here has a '+'
           character prepended to it then the current user accessing the share
           only has the primary group default assigned to this group if they
           are already assigned as a member of that group. This allows an
           administrator to decide that only users who are already in a
           particular group will create files with group ownership set to that
           group. This gives a finer granularity of ownership assignment. For
           example, the setting force group = +sys means that only users who
           are already in group sys will have their default primary group
           assigned to sys when accessing this Samba share. All other users
           will retain their ordinary primary group.

           If the force user parameter is also set the group specified in
           force group will override the primary group set in force user.

           Default: force group =

           Example: force group = agroup

       force printername (S)

           When printing from Windows NT (or later), each printer in smb.conf
           has two associated names which can be used by the client. The first
           is the sharename (or shortname) defined in smb.conf. This is the
           only printername available for use by Windows 9x clients. The
           second name associated with a printer can be seen when browsing to
           the "Printers" (or "Printers and Faxes") folder on the Samba
           server. This is referred to simply as the printername (not to be
           confused with the printer name option).

           When assigning a new driver to a printer on a remote Windows
           compatible print server such as Samba, the Windows client will
           rename the printer to match the driver name just uploaded. This can
           result in confusion for users when multiple printers are bound to
           the same driver. To prevent Samba from allowing the printer's
           printername to differ from the sharename defined in smb.conf, set
           force printername = yes.

           Be aware that enabling this parameter may affect migrating printers
           from a Windows server to Samba since Windows has no way to force
           the sharename and printername to match.

           It is recommended that this parameter's value not be changed once
           the printer is in use by clients as this could cause a user not be
           able to delete printer connections from their local Printers
           folder.

           Default: force printername = no

       force security mode (S)

           This parameter controls what UNIX permission bits can be modified
           when a Windows NT client is manipulating the UNIX permission on a
           file using the native NT security dialog box.

           This parameter is applied as a mask (OR'ed with) to the changed
           permission bits, thus forcing any bits in this mask that the user
           may have modified to be on. Make sure not to mix up this parameter
           with security mask, which works similar like this one but uses
           logical AND instead of OR.

           Essentially, one bits in this mask may be treated as a set of bits
           that, when modifying security on a file, the user has always set to
           be on.

           If not set explicitly this parameter is set to 0, and allows a user
           to modify all the user/group/world permissions on a file, with no
           restrictions.

            Note that users who can access the Samba server through other
           means can easily bypass this restriction, so it is primarily useful
           for standalone "appliance" systems. Administrators of most normal
           systems will probably want to leave this set to 0000.

           Default: force security mode = 0

           Example: force security mode = 700

       force unknown acl user (S)

           If this parameter is set, a Windows NT ACL that contains an unknown
           SID (security descriptor, or representation of a user or group id)
           as the owner or group owner of the file will be silently mapped
           into the current UNIX uid or gid of the currently connected user.

           This is designed to allow Windows NT clients to copy files and
           folders containing ACLs that were created locally on the client
           machine and contain users local to that machine only (no domain
           users) to be copied to a Samba server (usually with XCOPY /O) and
           have the unknown userid and groupid of the file owner map to the
           current connected user. This can only be fixed correctly when
           winbindd allows arbitrary mapping from any Windows NT SID to a UNIX
           uid or gid.

           Try using this parameter when XCOPY /O gives an ACCESS_DENIED
           error.

           Default: force unknown acl user = no

       force user (S)

           This specifies a UNIX user name that will be assigned as the
           default user for all users connecting to this service. This is
           useful for sharing files. You should also use it carefully as using
           it incorrectly can cause security problems.

           This user name only gets used once a connection is established.
           Thus clients still need to connect as a valid user and supply a
           valid password. Once connected, all file operations will be
           performed as the "forced user", no matter what username the client
           connected as. This can be very useful.

           In Samba 2.0.5 and above this parameter also causes the primary
           group of the forced user to be used as the primary group for all
           file activity. Prior to 2.0.5 the primary group was left as the
           primary group of the connecting user (this was a bug).

           Default: force user =

           Example: force user = auser

       fstype (S)

           This parameter allows the administrator to configure the string
           that specifies the type of filesystem a share is using that is
           reported by smbd(8) when a client queries the filesystem type for a
           share. The default type is NTFS for compatibility with Windows NT
           but this can be changed to other strings such as Samba or FAT if
           required.

           Default: fstype = NTFS

           Example: fstype = Samba

       get quota command (G)

           The get quota command should only be used whenever there is no
           operating system API available from the OS that samba can use.

           This option is only available with was used and a working quota api
           was found in the system.

           This parameter should specify the path to a script that queries the
           quota information for the specified user/group for the partition
           that the specified directory is on.

           Such a script should take 3 arguments:

           o   directory

           o   type of query

           o   uid of user or gid of group

           The type of query can be one of :

           o   1 - user quotas

           o   2 - user default quotas (uid = -1)

           o   3 - group quotas

           o   4 - group default quotas (gid = -1)

           This script should print one line as output with spaces between the
           arguments. The arguments are:

           o   Arg 1 - quota flags (0 = no quotas, 1 = quotas enabled, 2 =
               quotas enabled and enforced)

           o   Arg 2 - number of currently used blocks

           o   Arg 3 - the softlimit number of blocks

           o   Arg 4 - the hardlimit number of blocks

           o   Arg 5 - currently used number of inodes

           o   Arg 6 - the softlimit number of inodes

           o   Arg 7 - the hardlimit number of inodes

           o   Arg 8(optional) - the number of bytes in a block(default is
               1024)

           Default: get quota command =

           Example: get quota command = /usr/local/sbin/query_quota

       getwd cache (G)

           This is a tuning option. When this is enabled a caching algorithm
           will be used to reduce the time taken for getwd() calls. This can
           have a significant impact on performance, especially when the wide
           smbconfoptions parameter is set to no.

           Default: getwd cache = yes

       guest account (G)

           This is a username which will be used for access to services which
           are specified as guest ok (see below). Whatever privileges this
           user has will be available to any client connecting to the guest
           service. This user must exist in the password file, but does not
           require a valid login. The user account "ftp" is often a good
           choice for this parameter.

           On some systems the default guest account "nobody" may not be able
           to print. Use another account in this case. You should test this by
           trying to log in as your guest user (perhaps by using the su -
           command) and trying to print using the system print command such as
           lpr(1) or lp(1).

           This parameter does not accept % macros, because many parts of the
           system require this value to be constant for correct operation.

           Default: guest account = nobody # default can be changed at
           compile-time

           Example: guest account = ftp
       public.PP
           This parameter is a synonym for guest ok.

       guest ok (S)

           If this parameter is yes for a service, then no password is
           required to connect to the service. Privileges will be those of the
           guest account.

           This paramater nullifies the benifits of setting restrict anonymous
           = 2

           See the section below on security for more information about this
           option.

           Default: guest ok = no
       only guest.PP
           This parameter is a synonym for guest only.

       guest only (S)

           If this parameter is yes for a service, then only guest connections
           to the service are permitted. This parameter will have no effect if
           guest ok is not set for the service.

           See the section below on security for more information about this
           option.

           Default: guest only = no

       hide dot files (S)

           This is a boolean parameter that controls whether files starting
           with a dot appear as hidden files.

           Default: hide dot files = yes

       hide files (S)

           This is a list of files or directories that are not visible but are
           accessible. The DOS 'hidden' attribute is applied to any files or
           directories that match.

           Each entry in the list must be separated by a '/', which allows
           spaces to be included in the entry. '*' and '?' can be used to
           specify multiple files or directories as in DOS wildcards.

           Each entry must be a Unix path, not a DOS path and must not include
           the Unix directory separator '/'.

           Note that the case sensitivity option is applicable in hiding
           files.

           Setting this parameter will affect the performance of Samba, as it
           will be forced to check all files and directories for a match as
           they are scanned.

           The example shown above is based on files that the Macintosh SMB
           client (DAVE) available from Thursby creates for internal use, and
           also still hides all files beginning with a dot.

           An example of us of this parameter is:

               hide files = /.*/DesktopFolderDB/TrashFor%m/resource.frk/

           Default: hide files =  # no file are hidden

       hide special files (S)

           This parameter prevents clients from seeing special files such as
           sockets, devices and fifo's in directory listings.

           Default: hide special files = no

       hide unreadable (S)

           This parameter prevents clients from seeing the existance of files
           that cannot be read. Defaults to off.

           Default: hide unreadable = no

       hide unwriteable files (S)

           This parameter prevents clients from seeing the existance of files
           that cannot be written to. Defaults to off. Note that unwriteable
           directories are shown as usual.

           Default: hide unwriteable files = no

       homedir map (G)

           If nis homedir is yes, and smbd(8) is also acting as a Win95/98
           logon server then this parameter specifies the NIS (or YP) map from
           which the server for the user's home directory should be extracted.
           At present, only the Sun auto.home map format is understood. The
           form of the map is:

               username server:/some/file/system

           and the program will extract the servername from before the first
           ':'. There should probably be a better parsing system that copes
           with different map formats and also Amd (another automounter) maps.

           Note
           A working NIS client is required on the system for this option to
           work.

           Default: homedir map =

           Example: homedir map = amd.homedir

       host msdfs (G)

           If set to yes, Samba will act as a Dfs server, and allow Dfs-aware
           clients to browse Dfs trees hosted on the server.

           See also the msdfs root share level parameter. For more information
           on setting up a Dfs tree on Samba, refer to the MSFDS chapter in
           the book Samba3-HOWTO.

           Default: host msdfs = yes

       hostname lookups (G)

           Specifies whether samba should use (expensive) hostname lookups or
           use the ip addresses instead. An example place where hostname
           lookups are currently used is when checking the hosts deny and
           hosts allow.

           Default: hostname lookups = no

           Example: hostname lookups = yes
       allow hosts.PP
           This parameter is a synonym for hosts allow.

       hosts allow (S)

           A synonym for this parameter is allow hosts.

           This parameter is a comma, space, or tab delimited set of hosts
           which are permitted to access a service.

           If specified in the [global] section then it will apply to all
           services, regardless of whether the individual service has a
           different setting.

           You can specify the hosts by name or IP number. For example, you
           could restrict access to only the hosts on a Class C subnet with
           something like allow hosts = 150.203.5.. The full syntax of the
           list is described in the man page hosts_access(5). Note that this
           man page may not be present on your system, so a brief description
           will be given here also.

           Note that the localhost address 127.0.0.1 will always be allowed
           access unless specifically denied by a hosts deny option.

           You can also specify hosts by network/netmask pairs and by netgroup
           names if your system supports netgroups. The EXCEPT keyword can
           also be used to limit a wildcard list. The following examples may
           provide some help:

           Example 1: allow all IPs in 150.203.*.*; except one

           hosts allow = 150.203. EXCEPT 150.203.6.66

           Example 2: allow hosts that match the given network/netmask

           hosts allow = 150.203.15.0/255.255.255.0

           Example 3: allow a couple of hosts

           hosts allow = lapland, arvidsjaur

           Example 4: allow only hosts in NIS netgroup "foonet", but deny
           access from one particular host

           hosts allow = @foonet

           hosts deny = pirate

           Note
           Note that access still requires suitable user-level passwords.

           See testparm(1) for a way of testing your host access to see if it
           does what you expect.

           Default: hosts allow =  # none (i.e., all hosts permitted access)

           Example: hosts allow = 150.203.5. myhost.mynet.edu.au
       deny hosts.PP
           This parameter is a synonym for hosts deny.

       hosts deny (S)

           The opposite of hosts allow - hosts listed here are NOT permitted
           access to services unless the specific services have their own
           lists to override this one. Where the lists conflict, the allow
           list takes precedence.

           In the event that it is necessary to deny all by default, use the
           keyword ALL (or the netmask 0.0.0.0/0) and then explicitly specify
           to the hosts allow = hosts allow parameter those hosts that should
           be permitted access.

           Default: hosts deny =  # none (i.e., no hosts specifically
           excluded)

           Example: hosts deny = 150.203.4. badhost.mynet.edu.au

       idmap alloc backend (G)

           The idmap alloc backend provides a plugin interface for Winbind to
           use when allocating Unix uids/gids for Windows SIDs. This option is
           to be used in conjunction with the idmap domains parameter and
           refers to the name of the idmap module which will provide the id
           allocation functionality. Please refer to the man page for each
           idmap plugin to determine whether or not the module implements the
           allocation feature. The most common plugins are the tdb
           (idmap_tdb(8)) and ldap (idmap_ldap(8)) libraries.

           Also refer to the idmap alloc config option.

           No default

           Example: idmap alloc backend = tdb

       idmap alloc config (G)

           The idmap alloc config prefix provides a means of managing settings
           for the backend defined by the idmap alloc backend parameter. Refer
           to the man page for each idmap plugin regarding specific
           configuration details.

           No default

       idmap backend (G)

           The idmap backend provides a plugin interface for Winbind to use
           varying backends to store SID/uid/gid mapping tables. This option
           is mutually exclusive with the newer and more flexible idmap
           domains parameter. The main difference between the "idmap backend"
           and the "idmap domains" is that the former only allows on backend
           for all domains while the latter supports configuring backends on a
           per domain basis.

           Examples of SID/uid/gid backends include tdb (idmap_tdb(8)), ldap
           (idmap_ldap(8)), rid (idmap_rid(8)), and ad (idmap_tdb(8)).

           Default: idmap backend = tdb

       idmap cache time (G)

           This parameter specifies the number of seconds that Winbind's idmap
           interface will cache positive SID/uid/gid query results.

           Default: idmap cache time = 900

       idmap config (G)

           The idmap config prefix provides a means of managing each domain
           defined by the idmap domains option using Samba's parameteric
           option support. The idmap config prefix should be followed by the
           name of the domain, a colon, and a setting specific to the chosen
           backend. There are three options available for all domains:

           backend = backend_name
               Specifies the name of the idmap plugin to use as the
               SID/uid/gid backend for this domain.

           default = [yes|no]
               The default domain/backend will be used for searching for users
               and groups not belonging to one of the explicitly listed
               domains (matched by comparing the account SID and the domain
               SID).

           readonly = [yes|no]
               Mark the domain as readonly which means that no attempts to
               allocate a uid or gid (by the idmap alloc backend) for any user
               or group in that domain will be attempted.

           The following example illustrates how to configure the idmap_ad(8)
           for the CORP domain and the idmap_tdb(8) backend for all other
           domains. The TRUSTEDDOMAINS string is simply a key used to
           reference the "idmap config" settings and does not represent the
           actual name of a domain.

                    idmap domains = CORP TRUSTEDDOMAINS

                    idmap config CORP:backend  = ad
                    idmap config CORP:readonly = yes

                    idmap config TRUSTEDDOMAINS:backend = tdb
                    idmap config TRUSTEDDOMAINS:default = yes
                    idmap config TRUSTEDDOMAINS:range   = 1000 - 9999

           No default

       idmap domains (G)

           The idmap domains option defines a list of Windows domains which
           will each have a separately configured backend for managing
           Winbind's SID/uid/gid tables. This parameter is mutually exclusive
           with the older idmap backend option.

           Values consist of the short domain name for Winbind's primary or
           collection of trusted domains. You may also use an arbitrary string
           to represent a catchall domain backend for any domain not
           explicitly listed.

           Refer to the idmap config for details about managing the
           SID/uid/gid backend for each domain.

           No default

           Example: idmap domains = default AD CORP
       winbind gid.PP
           This parameter is a synonym for idmap gid.

       idmap gid (G)

           The idmap gid parameter specifies the range of group ids that are
           allocated for the purpose of mapping UNX groups to NT group SIDs.
           This range of group ids should have no existing local or NIS groups
           within it as strange conflicts can occur otherwise.

           See also the idmap backend, idmap domains, and idmap config
           options.

           Default: idmap gid =

           Example: idmap gid = 10000-20000

       idmap negative cache time (G)

           This parameter specifies the number of seconds that Winbind's idmap
           interface will cache negative SID/uid/gid query results.

           Default: idmap negative cache time = 120
       winbind uid.PP
           This parameter is a synonym for idmap uid.

       idmap uid (G)

           The idmap uid parameter specifies the range of user ids that are
           allocated for use in mapping UNIX users to NT user SIDs. This range
           of ids should have no existing local or NIS users within it as
           strange conflicts can occur otherwise.

           See also the idmap backend, idmap domains, and idmap config
           options.

           Default: idmap uid =

           Example: idmap uid = 10000-20000

       include (G)

           This allows you to include one config file inside another. The file
           is included literally, as though typed in place.

           It takes the standard substitutions, except %u, %P and %S.

           Default: include =

           Example: include = /usr/local/samba/lib/admin_smb.conf

       inherit acls (S)

           This parameter can be used to ensure that if default acls exist on
           parent directories, they are always honored when creating a new
           file or subdirectory in these parent directories. The default
           behavior is to use the unix mode specified when creating the
           directory. Enabling this option sets the unix mode to 0777, thus
           guaranteeing that default directory acls are propagated.

           Default: inherit acls = no

       inherit owner (S)

           The ownership of new files and directories is normally governed by
           effective uid of the connected user. This option allows the Samba
           administrator to specify that the ownership for new files and
           directories should be controlled by the ownership of the parent
           directory.

           Common scenarios where this behavior is useful is in implementing
           drop-boxes where users can create and edit files but not delete
           them and to ensure that newly create files in a user's roaming
           profile directory are actually owner by the user.

           Default: inherit owner = no

       inherit permissions (S)

           The permissions on new files and directories are normally governed
           by create mask, directory mask, force create mode and force
           directory mode but the boolean inherit permissions parameter
           overrides this.

           New directories inherit the mode of the parent directory, including
           bits such as setgid.

           New files inherit their read/write bits from the parent directory.
           Their execute bits continue to be determined by map archive, map
           hidden and map system as usual.

           Note that the setuid bit is never set via inheritance (the code
           explicitly prohibits this).

           This can be particularly useful on large systems with many users,
           perhaps several thousand, to allow a single [homes] share to be
           used flexibly by each user.

           Default: inherit permissions = no

       interfaces (G)

           This option allows you to override the default network interfaces
           list that Samba will use for browsing, name registration and other
           NBT traffic. By default Samba will query the kernel for the list of
           all active interfaces and use any interfaces except 127.0.0.1 that
           are broadcast capable.

           The option takes a list of interface strings. Each string can be in
           any of the following forms:

           o   a network interface name (such as eth0). This may include
               shell-like wildcards so eth* will match any interface starting
               with the substring "eth"

           o   an IP address. In this case the netmask is determined from the
               list of interfaces obtained from the kernel

           o   an IP/mask pair.

           o   a broadcast/mask pair.

           The "mask" parameters can either be a bit length (such as 24 for a
           C class network) or a full netmask in dotted decimal form.

           The "IP" parameters above can either be a full dotted decimal IP
           address or a hostname which will be looked up via the OS's normal
           hostname resolution mechanisms.

           By default Samba enables all active interfaces that are broadcast
           capable except the loopback adaptor (IP address 127.0.0.1).

           The example below configures three network interfaces corresponding
           to the eth0 device and IP addresses 192.168.2.10 and 192.168.3.10.
           The netmasks of the latter two interfaces would be set to
           255.255.255.0.

           Default: interfaces =

           Example: interfaces = eth0 192.168.2.10/24
           192.168.3.10/255.255.255.0

       invalid users (S)

           This is a list of users that should not be allowed to login to this
           service. This is really a paranoid check to absolutely ensure an
           improper setting does not breach your security.

           A name starting with a '@' is interpreted as an NIS netgroup first
           (if your system supports NIS), and then as a UNIX group if the name
           was not found in the NIS netgroup database.

           A name starting with '+' is interpreted only by looking in the UNIX
           group database via the NSS getgrnam() interface. A name starting
           with '&' is interpreted only by looking in the NIS netgroup
           database (this requires NIS to be working on your system). The
           characters '+' and '&' may be used at the start of the name in
           either order so the value +&group means check the UNIX group
           database, followed by the NIS netgroup database, and the value
           &+group means check the NIS netgroup database, followed by the UNIX
           group database (the same as the '@' prefix).

           The current servicename is substituted for %S. This is useful in
           the [homes] section.

           Default: invalid users =  # no invalid users

           Example: invalid users = root fred admin @wheel

       iprint server (G)

           This parameter is only applicable if printing is set to iprint.

           If set, this option overrides the ServerName option in the CUPS
           client.conf. This is necessary if you have virtual samba servers
           that connect to different CUPS daemons.

           Default: iprint server = ""

           Example: iprint server = MYCUPSSERVER

       keepalive (G)

           The value of the parameter (an integer) represents the number of
           seconds between keepalive packets. If this parameter is zero, no
           keepalive packets will be sent. Keepalive packets, if sent, allow
           the server to tell whether a client is still present and
           responding.

           Keepalives should, in general, not be needed if the socket has the
           SO_KEEPALIVE attribute set on it by default. (see socket options).
           Basically you should only use this option if you strike
           difficulties.

           Default: keepalive = 300

           Example: keepalive = 600

       kernel change notify (S)

           This parameter specifies whether Samba should ask the kernel for
           change notifications in directories so that SMB clients can refresh
           whenever the data on the server changes.

           This parameter is only used when your kernel supports change
           notification to user programs using the inotify interface.

           Default: kernel change notify = yes

       kernel oplocks (G)

           For UNIXes that support kernel based oplocks (currently only IRIX
           and the Linux 2.4 kernel), this parameter allows the use of them to
           be turned on or off.

           Kernel oplocks support allows Samba oplocks to be broken whenever a
           local UNIX process or NFS operation accesses a file that smbd(8)
           has oplocked. This allows complete data consistency between
           SMB/CIFS, NFS and local file access (and is a very cool feature
           :-).

           This parameter defaults to on, but is translated to a no-op on
           systems that no not have the necessary kernel support. You should
           never need to touch this parameter.

           Default: kernel oplocks = yes

       lanman auth (G)

           This parameter determines whether or not smbd(8) will attempt to
           authenticate users or permit password changes using the LANMAN
           password hash. If disabled, only clients which support NT password
           hashes (e.g. Windows NT/2000 clients, smbclient, but not Windows
           95/98 or the MS DOS network client) will be able to connect to the
           Samba host.

           The LANMAN encrypted response is easily broken, due to it's
           case-insensitive nature, and the choice of algorithm. Servers
           without Windows 95/98/ME or MS DOS clients are advised to disable
           this option.

           Unlike the encrypt passwords option, this parameter cannot alter
           client behaviour, and the LANMAN response will still be sent over
           the network. See the client lanman auth to disable this for Samba's
           clients (such as smbclient)

           If this option, and ntlm auth are both disabled, then only NTLMv2
           logins will be permited. Not all clients support NTLMv2, and most
           will require special configuration to use it.

           Default: lanman auth = yes

       large readwrite (G)

           This parameter determines whether or not smbd(8) supports the new
           64k streaming read and write varient SMB requests introduced with
           Windows 2000. Note that due to Windows 2000 client redirector bugs
           this requires Samba to be running on a 64-bit capable operating
           system such as IRIX, Solaris or a Linux 2.4 kernel. Can improve
           performance by 10% with Windows 2000 clients. Defaults to on. Not
           as tested as some other Samba code paths.

           Default: large readwrite = yes

       ldap admin dn (G)

           The ldap admin dn defines the Distinguished Name (DN) name used by
           Samba to contact the ldap server when retreiving user account
           information. The ldap admin dn is used in conjunction with the
           admin dn password stored in the private/secrets.tdb file. See the
           smbpasswd(8) man page for more information on how to accomplish
           this.

           The ldap admin dn requires a fully specified DN. The ldap suffix is
           not appended to the ldap admin dn.

           No default

       ldap delete dn (G)

           This parameter specifies whether a delete operation in the ldapsam
           deletes the complete entry or only the attributes specific to
           Samba.

           Default: ldap delete dn = no

       ldap group suffix (G)

           This parameter specifies the suffix that is used for groups when
           these are added to the LDAP directory. If this parameter is unset,
           the value of ldap suffix will be used instead. The suffix string is
           pre-pended to the ldap suffix string so use a partial DN.

           Default: ldap group suffix =

           Example: ldap group suffix = ou=Groups

       ldap idmap suffix (G)

           This parameters specifies the suffix that is used when storing
           idmap mappings. If this parameter is unset, the value of ldap
           suffix will be used instead. The suffix string is pre-pended to the
           ldap suffix string so use a partial DN.

           Default: ldap idmap suffix =

           Example: ldap idmap suffix = ou=Idmap

       ldap machine suffix (G)

           It specifies where machines should be added to the ldap tree. If
           this parameter is unset, the value of ldap suffix will be used
           instead. The suffix string is pre-pended to the ldap suffix string
           so use a partial DN.

           Default: ldap machine suffix =

           Example: ldap machine suffix = ou=Computers

       ldap passwd sync (G)

           This option is used to define whether or not Samba should sync the
           LDAP password with the NT and LM hashes for normal accounts (NOT
           for workstation, server or domain trusts) on a password change via
           SAMBA.

           The ldap passwd sync can be set to one of three values:

           o   Yes = Try to update the LDAP, NT and LM passwords and update
               the pwdLastSet time.

           o   No = Update NT and LM passwords and update the pwdLastSet time.

           o   Only = Only update the LDAP password and let the LDAP server do
               the rest.

           Default: ldap passwd sync = no

       ldap replication sleep (G)

           When Samba is asked to write to a read-only LDAP replica, we are
           redirected to talk to the read-write master server. This server
           then replicates our changes back to the 'local' server, however the
           replication might take some seconds, especially over slow links.
           Certain client activities, particularly domain joins, can become
           confused by the 'success' that does not immediately change the LDAP
           back-end's data.

           This option simply causes Samba to wait a short time, to allow the
           LDAP server to catch up. If you have a particularly high-latency
           network, you may wish to time the LDAP replication with a network
           sniffer, and increase this value accordingly. Be aware that no
           checking is performed that the data has actually replicated.

           The value is specified in milliseconds, the maximum value is 5000
           (5 seconds).

           Default: ldap replication sleep = 1000

       ldapsam:editposix (G)

           Editposix is an option that leverages ldapsam:trusted to make it
           simpler to manage a domain controller eliminating the need to set
           up custom scripts to add and manage the posix users and groups.
           This option will instead directly manipulate the ldap tree to
           create, remove and modify user and group entries. This option also
           requires a running winbindd as it is used to allocate new uids/gids
           on user/group creation. The allocation range must be therefore
           configured.

           To use this option, a basic ldap tree must be provided and the ldap
           suffix parameters must be properly configured. On virgin servers
           the default users and groups (Administrator, Guest, Domain Users,
           Domain Admins, Domain Guests) can be precreated with the command
           smbnet sam provision. To run this command the ldap server must be
           running, Winindd must be running and the smb.conf ldap options must
           be properly configured. The typical ldap setup used with the
           ldapsam:trusted = yes option is usually sufficient to use
           ldapsam:editposix = yes as well.

           An example configuration can be the following:

                    encrypt passwords = true
                    passdb backend = ldapsam

                    ldapsam:trusted=yes
                    ldapsam:editposix=yes

                    ldap admin dn = cn=admin,dc=samba,dc=org
                    ldap delete dn = yes
                    ldap group suffix = ou=groups
                    ldap idmap suffix = ou=idmap
                    ldap machine suffix = ou=computers
                    ldap user suffix = ou=users
                    ldap suffix = dc=samba,dc=org

                    idmap backend = ldap:"ldap://localhost"

                    idmap uid = 5000-50000
                    idmap gid = 5000-50000

           This configuration assume the ldap server have been loaded with a
           base tree like described in the following ldif:

                    dn: dc=samba,dc=org
                    objectClass: top
                    objectClass: dcObject
                    objectClass: organization
                    o: samba.org
                    dc: samba

                    dn: cn=admin,dc=samba,dc=org
                    objectClass: simpleSecurityObject
                    objectClass: organizationalRole
                    cn: admin
                    description: LDAP administrator
                    userPassword: secret

                    dn: ou=users,dc=samba,dc=org
                    objectClass: top
                    objectClass: organizationalUnit
                    ou: users

                    dn: ou=groups,dc=samba,dc=org
                    objectClass: top
                    objectClass: organizationalUnit
                    ou: groups

                    dn: ou=idmap,dc=samba,dc=org
                    objectClass: top
                    objectClass: organizationalUnit
                    ou: idmap

                    dn: ou=computers,dc=samba,dc=org
                    objectClass: top
                    objectClass: organizationalUnit
                    ou: computers

           Default: ldapsam:editposix = no

       ldapsam:trusted (G)

           By default, Samba as a Domain Controller with an LDAP backend needs
           to use the Unix-style NSS subsystem to access user and group
           information. Due to the way Unix stores user information in
           /etc/passwd and /etc/group this inevitably leads to inefficiencies.
           One important question a user needs to know is the list of groups
           he is member of. The plain UNIX model involves a complete
           enumeration of the file /etc/group and its NSS counterparts in
           LDAP. UNIX has optimized functions to enumerate group membership.
           Sadly, other functions that are used to deal with user and group
           attributes lack such optimization.

           To make Samba scale well in large environments, the ldapsam:trusted
           = yes option assumes that the complete user and group database that
           is relevant to Samba is stored in LDAP with the standard
           posixAccount/posixGroup attributes. It further assumes that the
           Samba auxiliary object classes are stored together with the POSIX
           data in the same LDAP object. If these assumptions are met,
           ldapsam:trusted = yes can be activated and Samba can bypass the NSS
           system to query user group memberships. Optimized LDAP queries can
           greatly speed up domain logon and administration tasks. Depending
           on the size of the LDAP database a factor of 100 or more for common
           queries is easily achieved.

           Default: ldapsam:trusted = no

       ldap ssl (G)

           This option is used to define whether or not Samba should use SSL
           when connecting to the ldap server This is NOT related to Samba's
           previous SSL support which was enabled by specifying the --with-ssl
           option to the configure script.

           The ldap ssl can be set to one of three values:

           o   Off = Never use SSL when querying the directory.

           o   Start_tls = Use the LDAPv3 StartTLS extended operation
               (RFC2830) for communicating with the directory server.

           o   On = Use SSL on the ldaps port when contacting the ldap server.
               Only available when the backwards-compatiblity --with-ldapsam
               option is specified to configure. See passdb backend
                         .sp
           Default: ldap ssl = start_tls

       ldap suffix (G)

           Specifies the base for all ldap suffixes and for storing the
           sambaDomain object.

           The ldap suffix will be appended to the values specified for the
           ldap user suffix, ldap group suffix, ldap machine suffix, and the
           ldap idmap suffix. Each of these should be given only a DN relative
           to the ldap suffix.

           Default: ldap suffix =

           Example: ldap suffix = dc=samba,dc=org

       ldap timeout (G)

           When Samba connects to an ldap server that servermay be down or
           unreachable. To prevent Samba from hanging whilst waiting for the
           connection this parameter specifies in seconds how long Samba
           should wait before failing the connect. The default is to only wait
           fifteen seconds for the ldap server to respond to the connect
           request.

           Default: ldap timeout = 15

       ldap user suffix (G)

           This parameter specifies where users are added to the tree. If this
           parameter is unset, the value of ldap suffix will be used instead.
           The suffix string is pre-pended to the ldap suffix string so use a
           partial DN.

           Default: ldap user suffix =

           Example: ldap user suffix = ou=people

       level2 oplocks (S)

           This parameter controls whether Samba supports level2 (read-only)
           oplocks on a share.

           Level2, or read-only oplocks allow Windows NT clients that have an
           oplock on a file to downgrade from a read-write oplock to a
           read-only oplock once a second client opens the file (instead of
           releasing all oplocks on a second open, as in traditional,
           exclusive oplocks). This allows all openers of the file that
           support level2 oplocks to cache the file for read-ahead only (ie.
           they may not cache writes or lock requests) and increases
           performance for many accesses of files that are not commonly
           written (such as application .EXE files).

           Once one of the clients which have a read-only oplock writes to the
           file all clients are notified (no reply is needed or waited for)
           and told to break their oplocks to "none" and delete any read-ahead
           caches.

           It is recommended that this parameter be turned on to speed access
           to shared executables.

           For more discussions on level2 oplocks see the CIFS spec.

           Currently, if kernel oplocks are supported then level2 oplocks are
           not granted (even if this parameter is set to yes). Note also, the
           oplocks parameter must be set to yes on this share in order for
           this parameter to have any effect.

           Default: level2 oplocks = yes

       lm announce (G)

           This parameter determines if nmbd(8) will produce Lanman announce
           broadcasts that are needed by OS/2 clients in order for them to see
           the Samba server in their browse list. This parameter can have
           three values, yes, no, or auto. The default is auto. If set to no
           Samba will never produce these broadcasts. If set to yes Samba will
           produce Lanman announce broadcasts at a frequency set by the
           parameter lm interval. If set to auto Samba will not send Lanman
           announce broadcasts by default but will listen for them. If it
           hears such a broadcast on the wire it will then start sending them
           at a frequency set by the parameter lm interval.

           Default: lm announce = auto

           Example: lm announce = yes

       lm interval (G)

           If Samba is set to produce Lanman announce broadcasts needed by
           OS/2 clients (see the lm announce parameter) then this parameter
           defines the frequency in seconds with which they will be made. If
           this is set to zero then no Lanman announcements will be made
           despite the setting of the lm announce parameter.

           Default: lm interval = 60

           Example: lm interval = 120

       load printers (G)

           A boolean variable that controls whether all printers in the
           printcap will be loaded for browsing by default. See the printers
           section for more details.

           Default: load printers = yes

       local master (G)

           This option allows nmbd(8) to try and become a local master browser
           on a subnet. If set to no then nmbd will not attempt to become a
           local master browser on a subnet and will also lose in all browsing
           elections. By default this value is set to yes. Setting this value
           to yes doesn't mean that Samba will become the local master browser
           on a subnet, just that nmbd will participate in elections for local
           master browser.

           Setting this value to no will cause nmbd never to become a local
           master browser.

           Default: local master = yes
       lock dir.PP
           This parameter is a synonym for lock directory.

       lock directory (G)

           This option specifies the directory where lock files will be
           placed. The lock files are used to implement the max connections
           option.

           Default: lock directory = ${prefix}/var/locks

           Example: lock directory = /var/run/samba/locks

       locking (S)

           This controls whether or not locking will be performed by the
           server in response to lock requests from the client.

           If locking = no, all lock and unlock requests will appear to
           succeed and all lock queries will report that the file in question
           is available for locking.

           If locking = yes, real locking will be performed by the server.

           This option may be useful for read-only filesystems which may not
           need locking (such as CDROM drives), although setting this
           parameter of no is not really recommended even in this case.

           Be careful about disabling locking either globally or in a specific
           service, as lack of locking may result in data corruption. You
           should never need to set this parameter.

           No default

       lock spin count (G)

           This parameter has been made inoperative in Samba 3.0.24. The
           functionality it contolled is now controlled by the parameter lock
           spin time.

           Default: lock spin count = 0

       lock spin time (G)

           The time in microseconds that smbd should keep waiting to see if a
           failed lock request can be granted. This parameter has changed in
           default value from Samba 3.0.23 from 10 to 200. The associated lock
           spin count parameter is no longer used in Samba 3.0.24. You should
           not need to change the value of this parameter.

           Default: lock spin time = 200

       log file (G)

           This option allows you to override the name of the Samba log file
           (also known as the debug file).

           This option takes the standard substitutions, allowing you to have
           separate log files for each user or machine.

           No default

           Example: log file = /usr/local/samba/var/log.%m
       debuglevel.PP
           This parameter is a synonym for log level.

       log level (G)

           The value of the parameter (a astring) allows the debug level
           (logging level) to be specified in the smb.conf file.

           This parameter has been extended since the 2.2.x series, now it
           allows to specify the debug level for multiple debug classes. This
           is to give greater flexibility in the configuration of the system.
           The following debug classes are currently implemented:

           o   all

           o   tdb

           o   printdrivers

           o   lanman

           o   smb

           o   rpc_parse

           o   rpc_srv

           o   rpc_cli

           o   passdb

           o   sam

           o   auth

           o   winbind

           o   vfs

           o   idmap

           o   quota

           o   acls

           o   locking

           o   msdfs

           o   dmapi

           o   registry

           Default: log level = 0

           Example: log level = 3 passdb:5 auth:10 winbind:2

       logon drive (G)

           This parameter specifies the local path to which the home directory
           will be connected (see logon home) and is only used by NT
           Workstations.

           Note that this option is only useful if Samba is set up as a logon
           server.

           Default: logon drive =

           Example: logon drive = h:

       logon home (G)

           This parameter specifies the home directory location when a
           Win95/98 or NT Workstation logs into a Samba PDC. It allows you to
           do

           C:\>NET USE H: /HOME

           from a command prompt, for example.

           This option takes the standard substitutions, allowing you to have
           separate logon scripts for each user or machine.

           This parameter can be used with Win9X workstations to ensure that
           roaming profiles are stored in a subdirectory of the user's home
           directory. This is done in the following way:

           logon home = \\%N\%U\profile

           This tells Samba to return the above string, with substitutions
           made when a client requests the info, generally in a NetUserGetInfo
           request. Win9X clients truncate the info to \\server\share when a
           user does smbnet use /home but use the whole string when dealing
           with profiles.

           Note that in prior versions of Samba, the logon path was returned
           rather than logon home. This broke smbnet use /home but allowed
           profiles outside the home directory. The current implementation is
           correct, and can be used for profiles if you use the above trick.

           Disable this feature by setting logon home = "" - using the empty
           string.

           This option is only useful if Samba is set up as a logon server.

           Default: logon home = \\%N\%U

           Example: logon home = \\remote_smb_server\%U

       logon path (G)

           This parameter specifies the directory where roaming profiles
           (Desktop, NTuser.dat, etc) are stored. Contrary to previous
           versions of these manual pages, it has nothing to do with Win 9X
           roaming profiles. To find out how to handle roaming profiles for
           Win 9X system, see the logon home parameter.

           This option takes the standard substitutions, allowing you to have
           separate logon scripts for each user or machine. It also specifies
           the directory from which the "Application Data", desktop, start
           menu, network neighborhood, programs and other folders, and their
           contents, are loaded and displayed on your Windows NT client.

           The share and the path must be readable by the user for the
           preferences and directories to be loaded onto the Windows NT
           client. The share must be writeable when the user logs in for the
           first time, in order that the Windows NT client can create the
           NTuser.dat and other directories. Thereafter, the directories and
           any of the contents can, if required, be made read-only. It is not
           advisable that the NTuser.dat file be made read-only - rename it to
           NTuser.man to achieve the desired effect (a MANdatory profile).

           Windows clients can sometimes maintain a connection to the [homes]
           share, even though there is no user logged in. Therefore, it is
           vital that the logon path does not include a reference to the homes
           share (i.e. setting this parameter to \\%N\homes\profile_path will
           cause problems).

           This option takes the standard substitutions, allowing you to have
           separate logon scripts for each user or machine.

           Warning
           Do not quote the value. Setting this as "\\%N\profile\%U" will
           break profile handling. Where the tdbsam or ldapsam passdb backend
           is used, at the time the user account is created the value
           configured for this parameter is written to the passdb backend and
           that value will over-ride the parameter value present in the
           smb.conf file. Any error present in the passdb backend account
           record must be editted using the appropriate tool (pdbedit on the
           command-line, or any other locally provided system tool).

           Note that this option is only useful if Samba is set up as a domain
           controller.

           Disable the use of roaming profiles by setting the value of this
           parameter to the empty string. For example, logon path = "". Take
           note that even if the default setting in the smb.conf file is the
           empty string, any value specified in the user account settings in
           the passdb backend will over-ride the effect of setting this
           parameter to null. Disabling of all roaming profile use requires
           that the user account settings must also be blank.

           An example of use is:

               logon path = \\PROFILESERVER\PROFILE\%U

           Default: logon path = \\%N\%U\profile

       logon script (G)

           This parameter specifies the batch file (.bat) or NT command file
           (.cmd) to be downloaded and run on a machine when a user
           successfully logs in. The file must contain the DOS style CR/LF
           line endings. Using a DOS-style editor to create the file is
           recommended.

           The script must be a relative path to the [netlogon] service. If
           the [netlogon] service specifies a path of
           /usr/local/samba/netlogon, and logon script = STARTUP.BAT, then the
           file that will be downloaded is:

                    /usr/local/samba/netlogon/STARTUP.BAT

           The contents of the batch file are entirely your choice. A
           suggested command would be to add NET TIME \\SERVER /SET /YES, to
           force every machine to synchronize clocks with the same time
           server. Another use would be to add NET USE U: \\SERVER\UTILS for
           commonly used utilities, or

               NET USE Q: \\SERVER\ISO9001_QA

           for example.

           Note that it is particularly important not to allow write access to
           the [netlogon] share, or to grant users write permission on the
           batch files in a secure environment, as this would allow the batch
           files to be arbitrarily modified and security to be breached.

           This option takes the standard substitutions, allowing you to have
           separate logon scripts for each user or machine.

           This option is only useful if Samba is set up as a logon server.

           Default: logon script =

           Example: logon script = scripts\%U.bat

       lppause command (S)

           This parameter specifies the command to be executed on the server
           host in order to stop printing or spooling a specific print job.

           This command should be a program or script which takes a printer
           name and job number to pause the print job. One way of implementing
           this is by using job priorities, where jobs having a too low
           priority won't be sent to the printer.

           If a %p is given then the printer name is put in its place. A %j is
           replaced with the job number (an integer). On HPUX (see
           printing=hpux ), if the -p%p option is added to the lpq command,
           the job will show up with the correct status, i.e. if the job
           priority is lower than the set fence priority it will have the
           PAUSED status, whereas if the priority is equal or higher it will
           have the SPOOLED or PRINTING status.

           Note that it is good practice to include the absolute path in the
           lppause command as the PATH may not be available to the server.

           Default: lppause command =  # Currently no default value is given
           to this string, unless the value of the printing parameter is SYSV,
           in which case the default is : lp -i %p-%j -H hold or if the value
           of the printing parameter is SOFTQ, then the default is: qstat -s
           -j%j -h.

           Example: lppause command = /usr/bin/lpalt %p-%j -p0

       lpq cache time (G)

           This controls how long lpq info will be cached for to prevent the
           lpq command being called too often. A separate cache is kept for
           each variation of the lpq command used by the system, so if you use
           different lpq commands for different users then they won't share
           cache information.

           The cache files are stored in /tmp/lpq.xxxx where xxxx is a hash of
           the lpq command in use.

           The default is 30 seconds, meaning that the cached results of a
           previous identical lpq command will be used if the cached data is
           less than 30 seconds old. A large value may be advisable if your
           lpq command is very slow.

           A value of 0 will disable caching completely.

           Default: lpq cache time = 30

           Example: lpq cache time = 10

       lpq command (S)

           This parameter specifies the command to be executed on the server
           host in order to obtain lpq-style printer status information.

           This command should be a program or script which takes a printer
           name as its only parameter and outputs printer status information.

           Currently nine styles of printer status information are supported;
           BSD, AIX, LPRNG, PLP, SYSV, HPUX, QNX, CUPS, and SOFTQ. This covers
           most UNIX systems. You control which type is expected using the
           printing = option.

           Some clients (notably Windows for Workgroups) may not correctly
           send the connection number for the printer they are requesting
           status information about. To get around this, the server reports on
           the first printer service connected to by the client. This only
           happens if the connection number sent is invalid.

           If a %p is given then the printer name is put in its place.
           Otherwise it is placed at the end of the command.

           Note that it is good practice to include the absolute path in the
           lpq command as the $PATH may not be available to the server. When
           compiled with the CUPS libraries, no lpq command is needed because
           smbd will make a library call to obtain the print queue listing.

           Default: lpq command =

           Example: lpq command = /usr/bin/lpq -P%p

       lpresume command (S)

           This parameter specifies the command to be executed on the server
           host in order to restart or continue printing or spooling a
           specific print job.

           This command should be a program or script which takes a printer
           name and job number to resume the print job. See also the lppause
           command parameter.

           If a %p is given then the printer name is put in its place. A %j is
           replaced with the job number (an integer).

           Note that it is good practice to include the absolute path in the
           lpresume command as the PATH may not be available to the server.

           See also the printing parameter.

           Default: Currently no default value is given to this string, unless
           the value of the printing parameter is SYSV, in which case the
           default is:

           lp -i %p-%j -H resume

           or if the value of the printing parameter is SOFTQ, then the
           default is:

           qstat -s -j%j -r

           No default

           Example: lpresume command = /usr/bin/lpalt %p-%j -p2

       lprm command (S)

           This parameter specifies the command to be executed on the server
           host in order to delete a print job.

           This command should be a program or script which takes a printer
           name and job number, and deletes the print job.

           If a %p is given then the printer name is put in its place. A %j is
           replaced with the job number (an integer).

           Note that it is good practice to include the absolute path in the
           lprm command as the PATH may not be available to the server.

           Examples of use are:

               lprm command = /usr/bin/lprm -P%p %j

               or

               lprm command = /usr/bin/cancel %p-%j

           Default: lprm command =  determined by printing parameter

       machine password timeout (G)

           If a Samba server is a member of a Windows NT Domain (see the
           security = domain parameter) then periodically a running smbd
           process will try and change the MACHINE ACCOUNT PASSWORD stored in
           the TDB called private/secrets.tdb . This parameter specifies how
           often this password will be changed, in seconds. The default is one
           week (expressed in seconds), the same as a Windows NT Domain member
           server.

           See also smbpasswd(8), and the security = domain parameter.

           Default: machine password timeout = 604800

       magic output (S)

           This parameter specifies the name of a file which will contain
           output created by a magic script (see the magic script parameter
           below).

           Warning
           If two clients use the same magic script in the same directory the
           output file content is undefined.

           Default: magic output = <magic script name>.out

           Example: magic output = myfile.txt

       magic script (S)

           This parameter specifies the name of a file which, if opened, will
           be executed by the server when the file is closed. This allows a
           UNIX script to be sent to the Samba host and executed on behalf of
           the connected user.

           Scripts executed in this way will be deleted upon completion
           assuming that the user has the appropriate level of privilege and
           the file permissions allow the deletion.

           If the script generates output, output will be sent to the file
           specified by the magic output parameter (see above).

           Note that some shells are unable to interpret scripts containing
           CR/LF instead of CR as the end-of-line marker. Magic scripts must
           be executable as is on the host, which for some hosts and some
           shells will require filtering at the DOS end.

           Magic scripts are EXPERIMENTAL and should NOT be relied upon.

           Default: magic script =

           Example: magic script = user.csh

       mangled map (S)

           This is for those who want to directly map UNIX file names which
           cannot be represented on Windows/DOS. The mangling of names is not
           always what is needed. In particular you may have documents with
           file extensions that differ between DOS and UNIX. For example,
           under UNIX it is common to use .html for HTML files, whereas under
           Windows/DOS .htm is more commonly used.

           So to map html to htm you would use:

           mangled map = (*.html *.htm).

           One very useful case is to remove the annoying ;1 off the ends of
           filenames on some CDROMs (only visible under some UNIXes). To do
           this use a map of (*;1 *;).

           Default: mangled map =  # no mangled map

           Example: mangled map = (*;1 *;)

       mangled names (S)

           This controls whether non-DOS names under UNIX should be mapped to
           DOS-compatible names ("mangled") and made visible, or whether
           non-DOS names should simply be ignored.

           See the section on name mangling for details on how to control the
           mangling process.

           If mangling is used then the mangling algorithm is as follows:

           o   The first (up to) five alphanumeric characters before the
               rightmost dot of the filename are preserved, forced to upper
               case, and appear as the first (up to) five characters of the
               mangled name.

           o   A tilde "~" is appended to the first part of the mangled name,
               followed by a two-character unique sequence, based on the
               original root name (i.e., the original filename minus its final
               extension). The final extension is included in the hash
               calculation only if it contains any upper case characters or is
               longer than three characters.

               Note that the character to use may be specified using the
               mangling char option, if you don't like '~'.

           o   Files whose UNIX name begins with a dot will be presented as
               DOS hidden files. The mangled name will be created as for other
               filenames, but with the leading dot removed and "___" as its
               extension regardless of actual original extension (that's three
               underscores).

           The two-digit hash value consists of upper case alphanumeric
           characters.

           This algorithm can cause name collisions only if files in a
           directory share the same first five alphanumeric characters. The
           probability of such a clash is 1/1300.

           The name mangling (if enabled) allows a file to be copied between
           UNIX directories from Windows/DOS while retaining the long UNIX
           filename. UNIX files can be renamed to a new extension from
           Windows/DOS and will retain the same basename. Mangled names do not
           change between sessions.

           Default: mangled names = yes

       mangle prefix (G)

           controls the number of prefix characters from the original name
           used when generating the mangled names. A larger value will give a
           weaker hash and therefore more name collisions. The minimum value
           is 1 and the maximum value is 6.

           mangle prefix is effective only when mangling method is hash2.

           Default: mangle prefix = 1

           Example: mangle prefix = 4

       mangling char (S)

           This controls what character is used as the magic character in name
           mangling. The default is a '~' but this may interfere with some
           software. Use this option to set it to whatever you prefer. This is
           effective only when mangling method is hash.

           Default: mangling char = ~

           Example: mangling char = ^

       mangling method (G)

           controls the algorithm used for the generating the mangled names.
           Can take two different values, "hash" and "hash2". "hash" is the
           algorithm that was used used in Samba for many years and was the
           default in Samba 2.2.x "hash2" is now the default and is newer and
           considered a better algorithm (generates less collisions) in the
           names. Many Win32 applications store the mangled names and so
           changing to algorithms must not be done lightly as these
           applications may break unless reinstalled.

           Default: mangling method = hash2

           Example: mangling method = hash

       map acl inherit (S)

           This boolean parameter controls whether smbd(8) will attempt to map
           the 'inherit' and 'protected' access control entry flags stored in
           Windows ACLs into an extended attribute called user.SAMBA_PAI. This
           parameter only takes effect if Samba is being run on a platform
           that supports extended attributes (Linux and IRIX so far) and
           allows the Windows 2000 ACL editor to correctly use inheritance
           with the Samba POSIX ACL mapping code.

           Default: map acl inherit = no

       map archive (S)

           This controls whether the DOS archive attribute should be mapped to
           the UNIX owner execute bit. The DOS archive bit is set when a file
           has been modified since its last backup. One motivation for this
           option is to keep Samba/your PC from making any file it touches
           from becoming executable under UNIX. This can be quite annoying for
           shared source code, documents, etc...

           Note that this requires the create mask parameter to be set such
           that owner execute bit is not masked out (i.e. it must include
           100). See the parameter create mask for details.

           Default: map archive = yes

       map hidden (S)

           This controls whether DOS style hidden files should be mapped to
           the UNIX world execute bit.

           Note that this requires the create mask to be set such that the
           world execute bit is not masked out (i.e. it must include 001). See
           the parameter create mask for details.

           No default

       map read only (S)

           This controls how the DOS read only attribute should be mapped from
           a UNIX filesystem.

           This parameter can take three different values, which tell smbd(8)
           how to display the read only attribute on files, where either store
           dos attributes is set to No, or no extended attribute is present.
           If store dos attributes is set to yes then this parameter is
           ignored. This is a new parameter introduced in Samba version
           3.0.21.

           The three settings are :

           o    Yes - The read only DOS attribute is mapped to the inverse of
               the user or owner write bit in the unix permission mode set. If
               the owner write bit is not set, the read only attribute is
               reported as being set on the file.

           o    Permissions - The read only DOS attribute is mapped to the
               effective permissions of the connecting user, as evaluated by
               smbd(8) by reading the unix permissions and POSIX ACL (if
               present). If the connecting user does not have permission to
               modify the file, the read only attribute is reported as being
               set on the file.

           o    No - The read only DOS attribute is unaffected by permissions,
               and can only be set by the store dos attributes method. This
               may be useful for exporting mounted CDs.

           Default: map read only = yes

       map system (S)

           This controls whether DOS style system files should be mapped to
           the UNIX group execute bit.

           Note that this requires the create mask to be set such that the
           group execute bit is not masked out (i.e. it must include 010). See
           the parameter create mask for details.

           Default: map system = no

       map to guest (G)

           This parameter is only useful in SECURITY = security modes other
           than security = share and security = server - i.e.  user, and
           domain.

           This parameter can take four different values, which tell smbd(8)
           what to do with user login requests that don't match a valid UNIX
           user in some way.

           The four settings are :

           o   Never - Means user login requests with an invalid password are
               rejected. This is the default.

           o   Bad User - Means user logins with an invalid password are
               rejected, unless the username does not exist, in which case it
               is treated as a guest login and mapped into the guest account.

           o   Bad Password - Means user logins with an invalid password are
               treated as a guest login and mapped into the guest account.
               Note that this can cause problems as it means that any user
               incorrectly typing their password will be silently logged on as
               "guest" - and will not know the reason they cannot access files
               they think they should - there will have been no message given
               to them that they got their password wrong. Helpdesk services
               will hate you if you set the map to guest parameter this way
               :-).

           o   Bad Uid - Is only applicable when Samba is configured in some
               type of domain mode security (security = {domain|ads}) and
               means that user logins which are successfully authenticated but
               which have no valid Unix user account (and smbd is unable to
               create one) should be mapped to the defined guest account. This
               was the default behavior of Samba 2.x releases. Note that if a
               member server is running winbindd, this option should never be
               required because the nss_winbind library will export the
               Windows domain users and groups to the underlying OS via the
               Name Service Switch interface.

           Note that this parameter is needed to set up "Guest" share services
           when using security modes other than share and server. This is
           because in these modes the name of the resource being requested is
           not sent to the server until after the server has successfully
           authenticated the client so the server cannot make authentication
           decisions at the correct time (connection to the share) for "Guest"
           shares. This parameter is not useful with security = server as in
           this security mode no information is returned about whether a user
           logon failed due to a bad username or bad password, the same error
           is returned from a modern server in both cases.

           For people familiar with the older Samba releases, this parameter
           maps to the old compile-time setting of the
            GUEST_SESSSETUP value in local.h.

           Default: map to guest = Never

           Example: map to guest = Bad User

       max connections (S)

           This option allows the number of simultaneous connections to a
           service to be limited. If max connections is greater than 0 then
           connections will be refused if this number of connections to the
           service are already open. A value of zero mean an unlimited number
           of connections may be made.

           Record lock files are used to implement this feature. The lock
           files will be stored in the directory specified by the lock
           directory option.

           Default: max connections = 0

           Example: max connections = 10

       max disk size (G)

           This option allows you to put an upper limit on the apparent size
           of disks. If you set this option to 100 then all shares will appear
           to be not larger than 100 MB in size.

           Note that this option does not limit the amount of data you can put
           on the disk. In the above case you could still store much more than
           100 MB on the disk, but if a client ever asks for the amount of
           free disk space or the total disk size then the result will be
           bounded by the amount specified in max disk size.

           This option is primarily useful to work around bugs in some pieces
           of software that can't handle very large disks, particularly disks
           over 1GB in size.

           A max disk size of 0 means no limit.

           Default: max disk size = 0

           Example: max disk size = 1000

       max log size (G)

           This option (an integer in kilobytes) specifies the max size the
           log file should grow to. Samba periodically checks the size and if
           it is exceeded it will rename the file, adding a .old extension.

           A size of 0 means no limit.

           Default: max log size = 5000

           Example: max log size = 1000

       max mux (G)

           This option controls the maximum number of outstanding simultaneous
           SMB operations that Samba tells the client it will allow. You
           should never need to set this parameter.

           Default: max mux = 50

       max open files (G)

           This parameter limits the maximum number of open files that one
           smbd(8) file serving process may have open for a client at any one
           time. The default for this parameter is set very high (10,000) as
           Samba uses only one bit per unopened file.

           The limit of the number of open files is usually set by the UNIX
           per-process file descriptor limit rather than this parameter so you
           should never need to touch this parameter.

           Default: max open files = 10000

       max print jobs (S)

           This parameter limits the maximum number of jobs allowable in a
           Samba printer queue at any given moment. If this number is
           exceeded, smbd(8) will remote "Out of Space" to the client.

           Default: max print jobs = 1000

           Example: max print jobs = 5000
       protocol.PP
           This parameter is a synonym for max protocol.

       max protocol (G)

           The value of the parameter (a string) is the highest protocol level
           that will be supported by the server.

           Possible values are :

           o   CORE: Earliest version. No concept of user names.

           o   COREPLUS: Slight improvements on CORE for efficiency.

           o   LANMAN1: First
                modern version of the protocol. Long filename support.

           o   LANMAN2: Updates to Lanman1 protocol.

           o   NT1: Current up to date version of the protocol. Used by
               Windows NT. Known as CIFS.

           Normally this option should not be set as the automatic negotiation
           phase in the SMB protocol takes care of choosing the appropriate
           protocol.

           Default: max protocol = NT1

           Example: max protocol = LANMAN1

       max reported print jobs (S)

           This parameter limits the maximum number of jobs displayed in a
           port monitor for Samba printer queue at any given moment. If this
           number is exceeded, the excess jobs will not be shown. A value of
           zero means there is no limit on the number of print jobs reported.

           Default: max reported print jobs = 0

           Example: max reported print jobs = 1000

       max smbd processes (G)

           This parameter limits the maximum number of smbd(8) processes
           concurrently running on a system and is intended as a stopgap to
           prevent degrading service to clients in the event that the server
           has insufficient resources to handle more than this number of
           connections. Remember that under normal operating conditions, each
           user will have an smbd(8) associated with him or her to handle
           connections to all shares from a given host.

           Default: max smbd processes = 0

           Example: max smbd processes = 1000

       max stat cache size (G)

           This parameter limits the size in memory of any stat cache being
           used to speed up case insensitive name mappings. It represents the
           number of kilobyte (1024) units the stat cache can use. A value of
           zero, meaning unlimited, is not advisable due to increased memory
           useage. You should not need to change this parameter.

           Default: max stat cache size = 256

           Example: max stat cache size = 100

       max ttl (G)

           This option tells nmbd(8) what the default 'time to live' of
           NetBIOS names should be (in seconds) when nmbd is requesting a name
           using either a broadcast packet or from a WINS server. You should
           never need to change this parameter. The default is 3 days.

           Default: max ttl = 259200

       max wins ttl (G)

           This option tells smbd(8) when acting as a WINS server (wins
           support = yes) what the maximum 'time to live' of NetBIOS names
           that nmbd will grant will be (in seconds). You should never need to
           change this parameter. The default is 6 days (518400 seconds).

           Default: max wins ttl = 518400

       max xmit (G)

           This option controls the maximum packet size that will be
           negotiated by Samba. The default is 16644, which matches the
           behavior of Windows 2000. A value below 2048 is likely to cause
           problems. You should never need to change this parameter from its
           default value.

           Default: max xmit = 16644

           Example: max xmit = 8192

       message command (G)

           This specifies what command to run when the server receives a
           WinPopup style message.

           This would normally be a command that would deliver the message
           somehow. How this is to be done is up to your imagination.

           An example is:

               message command = csh -c 'xedit %s;rm %s' &

           This delivers the message using xedit, then removes it afterwards.
           NOTE THAT IT IS VERY IMPORTANT THAT THIS COMMAND RETURN
           IMMEDIATELY. That's why I have the '&' on the end. If it doesn't
           return immediately then your PCs may freeze when sending messages
           (they should recover after 30 seconds, hopefully).

           All messages are delivered as the global guest user. The command
           takes the standard substitutions, although
            %u won't work (%U may be better in this case).

           Apart from the standard substitutions, some additional ones apply.
           In particular:

           o   %s = the filename containing the message.

           o   %t = the destination that the message was sent to (probably the
               server name).

           o   %f = who the message is from.

           You could make this command send mail, or whatever else takes your
           fancy. Please let us know of any really interesting ideas you have.

           Here's a way of sending the messages as mail to root:

               message command = /bin/mail -s 'message from %f on %m' root < %s; rm %s

           If you don't have a message command then the message won't be
           delivered and Samba will tell the sender there was an error.
           Unfortunately WfWg totally ignores the error code and carries on
           regardless, saying that the message was delivered.

           If you want to silently delete it then try:

               message command = rm %s

           Default: message command =

           Example: message command = csh -c 'xedit %s; rm %s' &

       min print space (S)

           This sets the minimum amount of free disk space that must be
           available before a user will be able to spool a print job. It is
           specified in kilobytes. The default is 0, which means a user can
           always spool a print job.

           Default: min print space = 0

           Example: min print space = 2000

       min protocol (G)

           The value of the parameter (a string) is the lowest SMB protocol
           dialect than Samba will support. Please refer to the max protocol
           parameter for a list of valid protocol names and a brief
           description of each. You may also wish to refer to the C source
           code in source/smbd/negprot.c for a listing of known protocol
           dialects supported by clients.

           If you are viewing this parameter as a security measure, you should
           also refer to the lanman auth parameter. Otherwise, you should
           never need to change this parameter.

           Default: min protocol = CORE

           Example: min protocol = NT1

       min wins ttl (G)

           This option tells nmbd(8) when acting as a WINS server (wins
           support = yes) what the minimum 'time to live' of NetBIOS names
           that nmbd will grant will be (in seconds). You should never need to
           change this parameter. The default is 6 hours (21600 seconds).

           Default: min wins ttl = 21600

       msdfs proxy (S)

           This parameter indicates that the share is a stand-in for another
           CIFS share whose location is specified by the value of the
           parameter. When clients attempt to connect to this share, they are
           redirected to the proxied share using the SMB-Dfs protocol.

           Only Dfs roots can act as proxy shares. Take a look at the msdfs
           root and host msdfs options to find out how to set up a Dfs root
           share.

           No default

           Example: msdfs proxy = \otherserver\someshare

       msdfs root (S)

           If set to yes, Samba treats the share as a Dfs root and allows
           clients to browse the distributed file system tree rooted at the
           share directory. Dfs links are specified in the share directory by
           symbolic links of the form msdfs:serverA\\shareA,serverB\\shareB
           and so on. For more information on setting up a Dfs tree on Samba,
           refer to the MSDFS chapter in the Samba3-HOWTO book.

           Default: msdfs root = no

       name cache timeout (G)

           Specifies the number of seconds it takes before entries in samba's
           hostname resolve cache time out. If the timeout is set to 0. the
           caching is disabled.

           Default: name cache timeout = 660

           Example: name cache timeout = 0

       name resolve order (G)

           This option is used by the programs in the Samba suite to determine
           what naming services to use and in what order to resolve host names
           to IP addresses. Its main purpose to is to control how netbios name
           resolution is performed. The option takes a space separated string
           of name resolution options.

           The options are: "lmhosts", "host", "wins" and "bcast". They cause
           names to be resolved as follows:

           o    lmhosts : Lookup an IP address in the Samba lmhosts file. If
               the line in lmhosts has no name type attached to the NetBIOS
               name (see the manpage for lmhosts for details) then any name
               type matches for lookup.

           o    host : Do a standard host name to IP address resolution, using
               the system /etc/hosts , NIS, or DNS lookups. This method of
               name resolution is operating system depended for instance on
               IRIX or Solaris this may be controlled by the
               /etc/nsswitch.conf file. Note that this method is used only if
               the NetBIOS name type being queried is the 0x20 (server) name
               type or 0x1c (domain controllers). The latter case is only
               useful for active directory domains and results in a DNS query
               for the SRV RR entry matching _ldap._tcp.domain.

           o   wins : Query a name with the IP address listed in the
               WINSSERVER parameter. If no WINS server has been specified this
               method will be ignored.

           o   bcast : Do a broadcast on each of the known local interfaces
               listed in the interfaces parameter. This is the least reliable
               of the name resolution methods as it depends on the target host
               being on a locally connected subnet.

           The example below will cause the local lmhosts file to be examined
           first, followed by a broadcast attempt, followed by a normal system
           hostname lookup.

           When Samba is functioning in ADS security mode (security = ads) it
           is advised to use following settings for name resolve order:

           name resolve order = wins bcast

           DC lookups will still be done via DNS, but fallbacks to netbios
           names will not inundate your DNS servers with needless querys for
           DOMAIN<0x1c> lookups.

           Default: name resolve order = lmhosts host wins bcast

           Example: name resolve order = lmhosts bcast host

       netbios aliases (G)

           This is a list of NetBIOS names that nmbd will advertise as
           additional names by which the Samba server is known. This allows
           one machine to appear in browse lists under multiple names. If a
           machine is acting as a browse server or logon server none of these
           names will be advertised as either browse server or logon servers,
           only the primary name of the machine will be advertised with these
           capabilities.

           Default: netbios aliases =  # empty string (no additional names)

           Example: netbios aliases = TEST TEST1 TEST2

       netbios name (G)

           This sets the NetBIOS name by which a Samba server is known. By
           default it is the same as the first component of the host's DNS
           name. If a machine is a browse server or logon server this name (or
           the first component of the hosts DNS name) will be the name that
           these services are advertised under.

           There is a bug in Samba-3 that breaks operation of browsing and
           access to shares if the netbios name is set to the literal name
           PIPE. To avoid this problem, do not name your Samba-3 server PIPE.

           Default: netbios name =  # machine DNS name

           Example: netbios name = MYNAME

       netbios scope (G)

           This sets the NetBIOS scope that Samba will operate under. This
           should not be set unless every machine on your LAN also sets this
           value.

           Default: netbios scope =

       nis homedir (G)

           Get the home share server from a NIS map. For UNIX systems that use
           an automounter, the user's home directory will often be mounted on
           a workstation on demand from a remote server.

           When the Samba logon server is not the actual home directory
           server, but is mounting the home directories via NFS then two
           network hops would be required to access the users home directory
           if the logon server told the client to use itself as the SMB server
           for home directories (one over SMB and one over NFS). This can be
           very slow.

           This option allows Samba to return the home share as being on a
           different server to the logon server and as long as a Samba daemon
           is running on the home directory server, it will be mounted on the
           Samba client directly from the directory server. When Samba is
           returning the home share to the client, it will consult the NIS map
           specified in homedir map and return the server listed there.

           Note that for this option to work there must be a working NIS
           system and the Samba server with this option must also be a logon
           server.

           Default: nis homedir = no

       nt acl support (S)

           This boolean parameter controls whether smbd(8) will attempt to map
           UNIX permissions into Windows NT access control lists. The UNIX
           permissions considered are the the traditional UNIX owner and group
           permissions, as well as POSIX ACLs set on any files or directories.
           This parameter was formally a global parameter in releases prior to
           2.2.2.

           Default: nt acl support = yes

       ntlm auth (G)

           This parameter determines whether or not smbd(8) will attempt to
           authenticate users using the NTLM encrypted password response. If
           disabled, either the lanman password hash or an NTLMv2 response
           will need to be sent by the client.

           If this option, and lanman auth are both disabled, then only NTLMv2
           logins will be permited. Not all clients support NTLMv2, and most
           will require special configuration to us it.

           Default: ntlm auth = yes

       nt pipe support (G)

           This boolean parameter controls whether smbd(8) will allow Windows
           NT clients to connect to the NT SMB specific IPC$ pipes. This is a
           developer debugging option and can be left alone.

           Default: nt pipe support = yes

       nt status support (G)

           This boolean parameter controls whether smbd(8) will negotiate NT
           specific status support with Windows NT/2k/XP clients. This is a
           developer debugging option and should be left alone. If this option
           is set to no then Samba offers exactly the same DOS error codes
           that versions prior to Samba 2.2.3 reported.

           You should not need to ever disable this parameter.

           Default: nt status support = yes

       null passwords (G)

           Allow or disallow client access to accounts that have null
           passwords.

           See also smbpasswd(5).

           Default: null passwords = no

       obey pam restrictions (G)

           When Samba 3.0 is configured to enable PAM support (i.e.
           --with-pam), this parameter will control whether or not Samba
           should obey PAM's account and session management directives. The
           default behavior is to use PAM for clear text authentication only
           and to ignore any account or session management. Note that Samba
           always ignores PAM for authentication in the case of encrypt
           passwords = yes. The reason is that PAM modules cannot support the
           challenge/response authentication mechanism needed in the presence
           of SMB password encryption.

           Default: obey pam restrictions = no

       only user (S)

           This is a boolean option that controls whether connections with
           usernames not in the user list will be allowed. By default this
           option is disabled so that a client can supply a username to be
           used by the server. Enabling this parameter will force the server
           to only use the login names from the user list and is only really
           useful in security = share level security.

           Note that this also means Samba won't try to deduce usernames from
           the service name. This can be annoying for the [homes] section. To
           get around this you could use user = %S which means your user list
           will be just the service name, which for home directories is the
           name of the user.

           Default: only user = no

       open files database hash size (G)

           This parameter was added in Samba 3.0.23. This is an internal
           tuning parameter that sets the hash size of the tdb used for the
           open file databases. The presence of this parameter allows tuning
           of the system for very large (thousands of concurrent users) Samba
           setups. The default setting of this parameter should be sufficient
           for most normal environments. It is advised not to change this
           parameter unless advised to by a Samba Team member.

           Default: open files database hash size = 10007

           Example: open files database hash size = 1338457

       oplock break wait time (G)

           This is a tuning parameter added due to bugs in both Windows 9x and
           WinNT. If Samba responds to a client too quickly when that client
           issues an SMB that can cause an oplock break request, then the
           network client can fail and not respond to the break request. This
           tuning parameter (which is set in milliseconds) is the amount of
           time Samba will wait before sending an oplock break request to such
           (broken) clients.

           Warning
           DO NOT CHANGE THIS PARAMETER UNLESS YOU HAVE READ AND UNDERSTOOD
           THE SAMBA OPLOCK CODE.

           Default: oplock break wait time = 0

       oplock contention limit (S)

           This is a very advanced smbd(8) tuning option to improve the
           efficiency of the granting of oplocks under multiple client
           contention for the same file.

           In brief it specifies a number, which causes smbd(8)not to grant an
           oplock even when requested if the approximate number of clients
           contending for an oplock on the same file goes over this limit.
           This causes smbd to behave in a similar way to Windows NT.

           Warning
           DO NOT CHANGE THIS PARAMETER UNLESS YOU HAVE READ AND UNDERSTOOD
           THE SAMBA OPLOCK CODE.

           Default: oplock contention limit = 2

       oplocks (S)

           This boolean option tells smbd whether to issue oplocks
           (opportunistic locks) to file open requests on this share. The
           oplock code can dramatically (approx. 30% or more) improve the
           speed of access to files on Samba servers. It allows the clients to
           aggressively cache files locally and you may want to disable this
           option for unreliable network environments (it is turned on by
           default in Windows NT Servers). For more information see the file
           Speed.txt in the Samba docs/ directory.

           Oplocks may be selectively turned off on certain files with a
           share. See the veto oplock files parameter. On some systems oplocks
           are recognized by the underlying operating system. This allows data
           synchronization between all access to oplocked files, whether it be
           via Samba or NFS or a local UNIX process. See the kernel oplocks
           parameter for details.

           Default: oplocks = yes

       os2 driver map (G)

           The parameter is used to define the absolute path to a file
           containing a mapping of Windows NT printer driver names to OS/2
           printer driver names. The format is:

           <nt driver name> = <os2 driver name>.<device name>

           For example, a valid entry using the HP LaserJet 5 printer driver
           would appear as HP LaserJet 5L = LASERJET.HP LaserJet 5L.

           The need for the file is due to the printer driver namespace
           problem described in the chapter on Classical Printing in the
           Samba3-HOWTO book. For more details on OS/2 clients, please refer
           to chapter on other clients in the Samba3-HOWTO book.

           Default: os2 driver map =

       os level (G)

           This integer value controls what level Samba advertises itself as
           for browse elections. The value of this parameter determines
           whether nmbd(8) has a chance of becoming a local master browser for
           the workgroup in the local broadcast area.

            Note: By default, Samba will win a local master browsing election
           over all Microsoft operating systems except a Windows NT 4.0/2000
           Domain Controller. This means that a misconfigured Samba host can
           effectively isolate a subnet for browsing purposes. This parameter
           is largely auto-configured in the Samba-3 release series and it is
           seldom necessary to manually override the default setting. Please
           refer to chapter 9 of the Samba-3 HOWTO document for further
           information regarding the use of this parameter.  Note: The maximum
           value for this parameter is 255. If you use higher values, counting
           will start at 0!

           Default: os level = 20

           Example: os level = 65

       pam password change (G)

           With the addition of better PAM support in Samba 2.2, this
           parameter, it is possible to use PAM's password change control flag
           for Samba. If enabled, then PAM will be used for password changes
           when requested by an SMB client instead of the program listed in
           passwd program. It should be possible to enable this without
           changing your passwd chat parameter for most setups.

           Default: pam password change = no

       panic action (G)

           This is a Samba developer option that allows a system command to be
           called when either smbd(8) or nmbd(8) crashes. This is usually used
           to draw attention to the fact that a problem occurred.

           Default: panic action =

           Example: panic action = "/bin/sleep 90000"

       paranoid server security (G)

           Some version of NT 4.x allow non-guest users with a bad passowrd.
           When this option is enabled, samba will not use a broken NT 4.x
           server as password server, but instead complain to the logs and
           exit.

           Disabling this option prevents Samba from making this check, which
           involves deliberatly attempting a bad logon to the remote server.

           Default: paranoid server security = yes

       passdb backend (G)

           This option allows the administrator to chose which backend will be
           used for storing user and possibly group information. This allows
           you to swap between different storage mechanisms without recompile.

           The parameter value is divided into two parts, the backend's name,
           and a 'location' string that has meaning only to that particular
           backed. These are separated by a : character.

           Available backends can include:

           o   smbpasswd - The default smbpasswd backend. Takes a path to the
               smbpasswd file as an optional argument.

           o   tdbsam - The TDB based password storage backend. Takes a path
               to the TDB as an optional argument (defaults to passdb.tdb in
               the private dir directory.

           o   ldapsam - The LDAP based passdb backend. Takes an LDAP URL as
               an optional argument (defaults to ldap://localhost)

               LDAP connections should be secured where possible. This may be
               done using either Start-TLS (see ldap ssl) or by specifying
               ldaps:// in the URL argument.

               Multiple servers may also be specified in double-quotes.
               Whether multiple servers are supported or not and the exact
               syntax depends on the LDAP library you use.

                Examples of use are:

               passdb backend = tdbsam:/etc/samba/private/passdb.tdb

               or multi server LDAP URL with OpenLDAP library:

               passdb backend = ldapsam:"ldap://ldap-1.example.com ldap://ldap-2.example.com"

               or multi server LDAP URL with Netscape based LDAP library:

               passdb backend = ldapsam:"ldap://ldap-1.example.com ldap-2.example.com"
           Default: passdb backend = smbpasswd

       passdb expand explicit (G)

           This parameter controls whether Samba substitutes %-macros in the
           passdb fields if they are explicitly set. We used to expand macros
           here, but this turned out to be a bug because the Windows client
           can expand a variable %G_osver% in which %G would have been
           substituted by the user's primary group.

           Default: passdb expand explicit = no

       passwd chat debug (G)

           This boolean specifies if the passwd chat script parameter is run
           in debug mode. In this mode the strings passed to and received from
           the passwd chat are printed in the smbd(8) log with a debug level
           of 100. This is a dangerous option as it will allow plaintext
           passwords to be seen in the smbd log. It is available to help Samba
           admins debug their passwd chat scripts when calling the passwd
           program and should be turned off after this has been done. This
           option has no effect if the pam password change parameter is set.
           This parameter is off by default.

           Default: passwd chat debug = no

       passwd chat timeout (G)

           This integer specifies the number of seconds smbd will wait for an
           initial answer from a passwd chat script being run. Once the
           initial answer is received the subsequent answers must be received
           in one tenth of this time. The default it two seconds.

           Default: passwd chat timeout = 2

       passwd chat (G)

           This string controls the "chat" conversation that takes places
           between smbd(8) and the local password changing program to change
           the user's password. The string describes a sequence of
           response-receive pairs that smbd(8) uses to determine what to send
           to the passwd program and what to expect back. If the expected
           output is not received then the password is not changed.

           This chat sequence is often quite site specific, depending on what
           local methods are used for password control (such as NIS etc).

           Note that this parameter only is only used if the unix password
           sync parameter is set to yes. This sequence is then called AS ROOT
           when the SMB password in the smbpasswd file is being changed,
           without access to the old password cleartext. This means that root
           must be able to reset the user's password without knowing the text
           of the previous password. In the presence of NIS/YP, this means
           that the passwd program must be executed on the NIS master.

           The string can contain the macro %n which is substituted for the
           new password. The old passsword (%o) is only available when encrypt
           passwords has been disabled. The chat sequence can also contain the
           standard macros \n, \r, \t and \s to give line-feed,
           carriage-return, tab and space. The chat sequence string can also
           contain a '*' which matches any sequence of characters. Double
           quotes can be used to collect strings with spaces in them into a
           single string.

           If the send string in any part of the chat sequence is a full stop
           ".", then no string is sent. Similarly, if the expect string is a
           full stop then no string is expected.

           If the pam password change parameter is set to yes, the chat pairs
           may be matched in any order, and success is determined by the PAM
           result, not any particular output. The \n macro is ignored for PAM
           conversions.

           Default: passwd chat = *new*password* %n\n*new*password* %n\n
           *changed*

           Example: passwd chat = "*Enter NEW password*" %n\n "*Reenter NEW
           password*" %n\n "*Password changed*"

       passwd program (G)

           The name of a program that can be used to set UNIX user passwords.
           Any occurrences of %u will be replaced with the user name. The user
           name is checked for existence before calling the password changing
           program.

           Also note that many passwd programs insist in reasonable passwords,
           such as a minimum length, or the inclusion of mixed case chars and
           digits. This can pose a problem as some clients (such as Windows
           for Workgroups) uppercase the password before sending it.

           Note that if the unix password sync parameter is set to yes then
           this program is called AS ROOT before the SMB password in the
           smbpasswd file is changed. If this UNIX password change fails, then
           smbd will fail to change the SMB password also (this is by design).

           If the unix password sync parameter is set this parameter MUST USE
           ABSOLUTE PATHS for ALL programs called, and must be examined for
           security implications. Note that by default unix password sync is
           set to no.

           Default: passwd program =

           Example: passwd program = /bin/passwd %u

       password level (G)

           Some client/server combinations have difficulty with mixed-case
           passwords. One offending client is Windows for Workgroups, which
           for some reason forces passwords to upper case when using the
           LANMAN1 protocol, but leaves them alone when using COREPLUS!
           Another problem child is the Windows 95/98 family of operating
           systems. These clients upper case clear text passwords even when NT
           LM 0.12 selected by the protocol negotiation request/response.

           This parameter defines the maximum number of characters that may be
           upper case in passwords.

           For example, say the password given was "FRED". If
            password level is set to 1, the following combinations would be
           tried if "FRED" failed:

           "Fred", "fred", "fRed", "frEd","freD"

           If password level was set to 2, the following combinations would
           also be tried:

           "FRed", "FrEd", "FreD", "fREd", "fReD", "frED", ..

           And so on.

           The higher value this parameter is set to the more likely it is
           that a mixed case password will be matched against a single case
           password. However, you should be aware that use of this parameter
           reduces security and increases the time taken to process a new
           connection.

           A value of zero will cause only two attempts to be made - the
           password as is and the password in all-lower case.

           This parameter is used only when using plain-text passwords. It is
           not at all used when encrypted passwords as in use (that is the
           default since samba-3.0.0). Use this only when encrypt passwords =
           No.

           Default: password level = 0

           Example: password level = 4

       password server (G)

           By specifying the name of another SMB server or Active Directory
           domain controller with this option, and using security =
           [ads|domain|server] it is possible to get Samba to to do all its
           username/password validation using a specific remote server.

           This option sets the name or IP address of the password server to
           use. New syntax has been added to support defining the port to use
           when connecting to the server the case of an ADS realm. To define a
           port other than the default LDAP port of 389, add the port number
           using a colon after the name or IP address (e.g.
           192.168.1.100:389). If you do not specify a port, Samba will use
           the standard LDAP port of tcp/389. Note that port numbers have no
           effect on password servers for Windows NT 4.0 domains or netbios
           connections.

           If parameter is a name, it is looked up using the parameter name
           resolve order and so may resolved by any method and order described
           in that parameter.

           The password server must be a machine capable of using the
           "LM1.2X002" or the "NT LM 0.12" protocol, and it must be in user
           level security mode.

           Note
           Using a password server means your UNIX box (running Samba) is only
           as secure as your password server.  DO NOT CHOOSE A PASSWORD SERVER
           THAT YOU DON'T COMPLETELY TRUST.

           Never point a Samba server at itself for password serving. This
           will cause a loop and could lock up your Samba server!

           The name of the password server takes the standard substitutions,
           but probably the only useful one is %m , which means the Samba
           server will use the incoming client as the password server. If you
           use this then you better trust your clients, and you had better
           restrict them with hosts allow!

           If the security parameter is set to domain or ads, then the list of
           machines in this option must be a list of Primary or Backup Domain
           controllers for the Domain or the character '*', as the Samba
           server is effectively in that domain, and will use
           cryptographically authenticated RPC calls to authenticate the user
           logging on. The advantage of using security = domain is that if you
           list several hosts in the password server option then smbd will try
           each in turn till it finds one that responds. This is useful in
           case your primary server goes down.

           If the password server option is set to the character '*', then
           Samba will attempt to auto-locate the Primary or Backup Domain
           controllers to authenticate against by doing a query for the name
           WORKGROUP<1C> and then contacting each server returned in the list
           of IP addresses from the name resolution source.

           If the list of servers contains both names/IP's and the '*'
           character, the list is treated as a list of preferred domain
           controllers, but an auto lookup of all remaining DC's will be added
           to the list as well. Samba will not attempt to optimize this list
           by locating the closest DC.

           If the security parameter is set to server, then there are
           different restrictions that security = domain doesn't suffer from:

           o   You may list several password servers in the password server
               parameter, however if an smbd makes a connection to a password
               server, and then the password server fails, no more users will
               be able to be authenticated from this smbd. This is a
               restriction of the SMB/CIFS protocol when in security = server
               mode and cannot be fixed in Samba.

           o   If you are using a Windows NT server as your password server
               then you will have to ensure that your users are able to login
               from the Samba server, as when in security = server mode the
               network logon will appear to come from there rather than from
               the users workstation.

           Default: password server =

           Example: password server = NT-PDC, NT-BDC1, NT-BDC2, *

           Example: password server = windc.mydomain.com:389 192.168.1.101 *

           Example: password server = *
       directory.PP
           This parameter is a synonym for path.

       path (S)

           This parameter specifies a directory to which the user of the
           service is to be given access. In the case of printable services,
           this is where print data will spool prior to being submitted to the
           host for printing.

           For a printable service offering guest access, the service should
           be readonly and the path should be world-writeable and have the
           sticky bit set. This is not mandatory of course, but you probably
           won't get the results you expect if you do otherwise.

           Any occurrences of %u in the path will be replaced with the UNIX
           username that the client is using on this connection. Any
           occurrences of %m will be replaced by the NetBIOS name of the
           machine they are connecting from. These replacements are very
           useful for setting up pseudo home directories for users.

           Note that this path will be based on root dir if one was specified.

           Default: path =

           Example: path = /home/fred

       pid directory (G)

           This option specifies the directory where pid files will be placed.

           Default: pid directory = ${prefix}/var/locks

           Example: pid directory = pid directory = /var/run/

       posix locking (S)

           The smbd(8) daemon maintains an database of file locks obtained by
           SMB clients. The default behavior is to map this internal database
           to POSIX locks. This means that file locks obtained by SMB clients
           are consistent with those seen by POSIX compliant applications
           accessing the files via a non-SMB method (e.g. NFS or local file
           access). You should never need to disable this parameter.

           Default: posix locking = yes

       postexec (S)

           This option specifies a command to be run whenever the service is
           disconnected. It takes the usual substitutions. The command may be
           run as the root on some systems.

           An interesting example may be to unmount server resources:

           postexec = /etc/umount /cdrom

           Default: postexec =

           Example: postexec = echo \"%u disconnected from %S from %m (%I)\"
           >> /tmp/log

       preexec close (S)

           This boolean option controls whether a non-zero return code from
           preexec should close the service being connected to.

           Default: preexec close = no
       exec.PP
           This parameter is a synonym for preexec.

       preexec (S)

           This option specifies a command to be run whenever the service is
           connected to. It takes the usual substitutions.

           An interesting example is to send the users a welcome message every
           time they log in. Maybe a message of the day? Here is an example:

           preexec = csh -c 'echo \"Welcome to %S!\" |
           /usr/local/samba/bin/smbclient -M %m -I %I' &

           Of course, this could get annoying after a while :-)

           See also preexec close and postexec.

           Default: preexec =

           Example: preexec = echo \"%u connected to %S from %m (%I)\" >>
           /tmp/log
       prefered master.PP
           This parameter is a synonym for preferred master.

       preferred master (G)

           This boolean parameter controls if nmbd(8) is a preferred master
           browser for its workgroup.

           If this is set to yes, on startup, nmbd will force an election, and
           it will have a slight advantage in winning the election. It is
           recommended that this parameter is used in conjunction with domain
           master = yes, so that nmbd can guarantee becoming a domain master.

           Use this option with caution, because if there are several hosts
           (whether Samba servers, Windows 95 or NT) that are preferred master
           browsers on the same subnet, they will each periodically and
           continuously attempt to become the local master browser. This will
           result in unnecessary broadcast traffic and reduced browsing
           capabilities.

           Default: preferred master = auto

       preload modules (G)

           This is a list of paths to modules that should be loaded into smbd
           before a client connects. This improves the speed of smbd when
           reacting to new connections somewhat.

           Default: preload modules =

           Example: preload modules = /usr/lib/samba/passdb/mysql.so
       auto services.PP
           This parameter is a synonym for preload.

       preload (G)

           This is a list of services that you want to be automatically added
           to the browse lists. This is most useful for homes and printers
           services that would otherwise not be visible.

           Note that if you just want all printers in your printcap file
           loaded then the load printers option is easier.

           Default: preload =

           Example: preload = fred lp colorlp

       preserve case (S)

           This controls if new filenames are created with the case that the
           client passes, or if they are forced to be the default case.

           See the section on NAME MANGLING for a fuller discussion.

           Default: preserve case = yes
       print ok.PP
           This parameter is a synonym for printable.

       printable (S)

           If this parameter is yes, then clients may open, write to and
           submit spool files on the directory specified for the service.

           Note that a printable service will ALWAYS allow writing to the
           service path (user privileges permitting) via the spooling of print
           data. The read only parameter controls only non-printing access to
           the resource.

           Default: printable = no

       printcap cache time (G)

           This option specifies the number of seconds before the printing
           subsystem is again asked for the known printers. If the value is
           greater than 60 the initial waiting time is set to 60 seconds to
           allow an earlier first rescan of the printing subsystem.

           Setting this parameter to 0 disables any rescanning for new or
           removed printers after the initial startup.

           Default: printcap cache time = 750

           Example: printcap cache time = 600
       printcap.PP
           This parameter is a synonym for printcap name.

       printcap name (S)

           This parameter may be used to override the compiled-in default
           printcap name used by the server (usually
            /etc/printcap). See the discussion of the [printers] section above
           for reasons why you might want to do this.

           To use the CUPS printing interface set printcap name = cups. This
           should be supplemented by an addtional setting printing = cups in
           the [global] section.  printcap name = cups will use the "dummy"
           printcap created by CUPS, as specified in your CUPS configuration
           file.

           On System V systems that use lpstat to list available printers you
           can use printcap name = lpstat to automatically obtain lists of
           available printers. This is the default for systems that define
           SYSV at configure time in Samba (this includes most System V based
           systems). If
            printcap name is set to lpstat on these systems then Samba will
           launch lpstat -v and attempt to parse the output to obtain a
           printer list.

           A minimal printcap file would look something like this:

               print1|My Printer 1
               print2|My Printer 2
               print3|My Printer 3
               print4|My Printer 4
               print5|My Printer 5

           where the '|' separates aliases of a printer. The fact that the
           second alias has a space in it gives a hint to Samba that it's a
           comment.

           Note
           Under AIX the default printcap name is /etc/qconfig. Samba will
           assume the file is in AIX qconfig format if the string qconfig
           appears in the printcap filename.

           Default: printcap name = /etc/printcap

           Example: printcap name = /etc/myprintcap

       print command (S)

           After a print job has finished spooling to a service, this command
           will be used via a system() call to process the spool file.
           Typically the command specified will submit the spool file to the
           host's printing subsystem, but there is no requirement that this be
           the case. The server will not remove the spool file, so whatever
           command you specify should remove the spool file when it has been
           processed, otherwise you will need to manually remove old spool
           files.

           The print command is simply a text string. It will be used verbatim
           after macro substitutions have been made:

           %s, %f - the path to the spool file name

           %p - the appropriate printer name

           %J - the job name as transmitted by the client.

           %c - The number of printed pages of the spooled job (if known).

           %z - the size of the spooled print job (in bytes)

           The print command MUST contain at least one occurrence of %s or %f
           - the %p is optional. At the time a job is submitted, if no printer
           name is supplied the %p will be silently removed from the printer
           command.

           If specified in the [global] section, the print command given will
           be used for any printable service that does not have its own print
           command specified.

           If there is neither a specified print command for a printable
           service nor a global print command, spool files will be created but
           not processed and (most importantly) not removed.

           Note that printing may fail on some UNIXes from the nobody account.
           If this happens then create an alternative guest account that can
           print and set the guest account in the [global] section.

           You can form quite complex print commands by realizing that they
           are just passed to a shell. For example the following will log a
           print job, print the file, then remove it. Note that ';' is the
           usual separator for command in shell scripts.

           print command = echo Printing %s >> /tmp/print.log; lpr -P %p %s;
           rm %s

           You may have to vary this command considerably depending on how you
           normally print files on your system. The default for the parameter
           varies depending on the setting of the printing parameter.

           Default: For printing = BSD, AIX, QNX, LPRNG or PLP :

           print command = lpr -r -P%p %s

           For printing = SYSV or HPUX :

           print command = lp -c -d%p %s; rm %s

           For printing = SOFTQ :

           print command = lp -d%p -s %s; rm %s

           For printing = CUPS : If SAMBA is compiled against libcups, then
           printcap = cups uses the CUPS API to submit jobs, etc. Otherwise it
           maps to the System V commands with the -oraw option for printing,
           i.e. it uses lp -c -d%p -oraw; rm %s. With printing = cups, and if
           SAMBA is compiled against libcups, any manually set print command
           will be ignored.

           No default

           Example: print command = /usr/local/samba/bin/myprintscript %p %s

       printer admin (S)

           This lists users who can do anything to printers via the remote
           administration interfaces offered by MS-RPC (usually using a NT
           workstation). This parameter can be set per-share or globally.
           Note: The root user always has admin rights. Use caution with use
           in the global stanza as this can cause side effects.

           This parameter has been marked deprecated in favor of using the
           SePrintOperatorPrivilege and individual print security descriptors.
           It will be removed in a future release.

           Default: printer admin =

           Example: printer admin = admin, @staff
       printer.PP
           This parameter is a synonym for printer name.

       printer name (S)

           This parameter specifies the name of the printer to which print
           jobs spooled through a printable service will be sent.

           If specified in the [global] section, the printer name given will
           be used for any printable service that does not have its own
           printer name specified.

           The default value of the printer name may be lp on many systems.

           Default: printer name = none

           Example: printer name = laserwriter

       printing (S)

           This parameters controls how printer status information is
           interpreted on your system. It also affects the default values for
           the print command, lpq command, lppause command , lpresume command,
           and lprm command if specified in the [global] section.

           Currently nine printing styles are supported. They are BSD, AIX,
           LPRNG, PLP, SYSV, HPUX, QNX, SOFTQ, and CUPS.

           To see what the defaults are for the other print commands when
           using the various options use the testparm(1) program.

           This option can be set on a per printer basis. Please be aware
           however, that you must place any of the various printing commands
           (e.g. print command, lpq command, etc...) after defining the value
           for the printing option since it will reset the printing commands
           to default values.

           See also the discussion in the [printers] section.

           No default

       printjob username (S)

           This parameter specifies which user information will be passed to
           the printing system. Usually, the username is sent, but in some
           cases, e.g. the domain prefix is useful, too.

           Default: printjob username = %U

           Example: printjob username = %D\%U

       private dir (G)

           This parameters defines the directory smbd will use for storing
           such files as smbpasswd and secrets.tdb.

           Default: private dir = ${prefix}/private

       profile acls (S)

           This boolean parameter was added to fix the problems that people
           have been having with storing user profiles on Samba shares from
           Windows 2000 or Windows XP clients. New versions of Windows 2000 or
           Windows XP service packs do security ACL checking on the owner and
           ability to write of the profile directory stored on a local
           workstation when copied from a Samba share.

           When not in domain mode with winbindd then the security info copied
           onto the local workstation has no meaning to the logged in user
           (SID) on that workstation so the profile storing fails. Adding this
           parameter onto a share used for profile storage changes two things
           about the returned Windows ACL. Firstly it changes the owner and
           group owner of all reported files and directories to be
           BUILTIN\\Administrators, BUILTIN\\Users respectively (SIDs
           S-1-5-32-544, S-1-5-32-545). Secondly it adds an ACE entry of "Full
           Control" to the SID BUILTIN\\Users to every returned ACL. This will
           allow any Windows 2000 or XP workstation user to access the
           profile.

           Note that if you have multiple users logging on to a workstation
           then in order to prevent them from being able to access each others
           profiles you must remove the "Bypass traverse checking" advanced
           user right. This will prevent access to other users profile
           directories as the top level profile directory (named after the
           user) is created by the workstation profile code and has an ACL
           restricting entry to the directory tree to the owning user.

           Default: profile acls = no

       queuepause command (S)

           This parameter specifies the command to be executed on the server
           host in order to pause the printer queue.

           This command should be a program or script which takes a printer
           name as its only parameter and stops the printer queue, such that
           no longer jobs are submitted to the printer.

           This command is not supported by Windows for Workgroups, but can be
           issued from the Printers window under Windows 95 and NT.

           If a %p is given then the printer name is put in its place.
           Otherwise it is placed at the end of the command.

           Note that it is good practice to include the absolute path in the
           command as the PATH may not be available to the server.

           No default

           Example: queuepause command = disable %p

       queueresume command (S)

           This parameter specifies the command to be executed on the server
           host in order to resume the printer queue. It is the command to
           undo the behavior that is caused by the previous parameter
           (queuepause command).

           This command should be a program or script which takes a printer
           name as its only parameter and resumes the printer queue, such that
           queued jobs are resubmitted to the printer.

           This command is not supported by Windows for Workgroups, but can be
           issued from the Printers window under Windows 95 and NT.

           If a %p is given then the printer name is put in its place.
           Otherwise it is placed at the end of the command.

           Note that it is good practice to include the absolute path in the
           command as the PATH may not be available to the server.

           Default: queueresume command =

           Example: queueresume command = enable %p

       read bmpx (G)

           This boolean parameter controls whether smbd(8) will support the
           "Read Block Multiplex" SMB. This is now rarely used and defaults to
           no. You should never need to set this parameter.

           Default: read bmpx = no

       read list (S)

           This is a list of users that are given read-only access to a
           service. If the connecting user is in this list then they will not
           be given write access, no matter what the read only option is set
           to. The list can include group names using the syntax described in
           the invalid users parameter.

           This parameter will not work with the security = share in Samba
           3.0. This is by design.

           Default: read list =

           Example: read list = mary, @students

       read only (S)

           An inverted synonym is writeable.

           If this parameter is yes, then users of a service may not create or
           modify files in the service's directory.

           Note that a printable service (printable = yes) will ALWAYS allow
           writing to the directory (user privileges permitting), but only via
           spooling operations.

           Default: read only = yes

       read raw (G)

           This parameter controls whether or not the server will support the
           raw read SMB requests when transferring data to clients.

           If enabled, raw reads allow reads of 65535 bytes in one packet.
           This typically provides a major performance benefit.

           However, some clients either negotiate the allowable block size
           incorrectly or are incapable of supporting larger block sizes, and
           for these clients you may need to disable raw reads.

           In general this parameter should be viewed as a system tuning tool
           and left severely alone.

           Default: read raw = yes

       realm (G)

           This option specifies the kerberos realm to use. The realm is used
           as the ADS equivalent of the NT4 domain. It is usually set to the
           DNS name of the kerberos server.

           Default: realm =

           Example: realm = mysambabox.mycompany.com

       remote announce (G)

           This option allows you to setup nmbd(8)to periodically announce
           itself to arbitrary IP addresses with an arbitrary workgroup name.

           This is useful if you want your Samba server to appear in a remote
           workgroup for which the normal browse propagation rules don't work.
           The remote workgroup can be anywhere that you can send IP packets
           to.

           For example:

               remote announce = 192.168.2.255/SERVERS 192.168.4.255/STAFF

           the above line would cause nmbd to announce itself to the two given
           IP addresses using the given workgroup names. If you leave out the
           workgroup name then the one given in the workgroup parameter is
           used instead.

           The IP addresses you choose would normally be the broadcast
           addresses of the remote networks, but can also be the IP addresses
           of known browse masters if your network config is that stable.

           See the chapter on Network Browsing in the Samba-HOWTO book.

           Default: remote announce =

       remote browse sync (G)

           This option allows you to setup nmbd(8) to periodically request
           synchronization of browse lists with the master browser of a Samba
           server that is on a remote segment. This option will allow you to
           gain browse lists for multiple workgroups across routed networks.
           This is done in a manner that does not work with any non-Samba
           servers.

           This is useful if you want your Samba server and all local clients
           to appear in a remote workgroup for which the normal browse
           propagation rules don't work. The remote workgroup can be anywhere
           that you can send IP packets to.

           For example:

               remote browse sync = 192.168.2.255 192.168.4.255

           the above line would cause nmbd to request the master browser on
           the specified subnets or addresses to synchronize their browse
           lists with the local server.

           The IP addresses you choose would normally be the broadcast
           addresses of the remote networks, but can also be the IP addresses
           of known browse masters if your network config is that stable. If a
           machine IP address is given Samba makes NO attempt to validate that
           the remote machine is available, is listening, nor that it is in
           fact the browse master on its segment.

           The remote browse sync may be used on networks where there is no
           WINS server, and may be used on disjoint networks where each
           network has its own WINS server.

           Default: remote browse sync =

       rename user script (G)

           This is the full pathname to a script that will be run as root by
           smbd(8) under special circumstances described below.

           When a user with admin authority or SeAddUserPrivilege rights
           renames a user (e.g.: from the NT4 User Manager for Domains), this
           script will be run to rename the POSIX user. Two variables, %uold
           and %unew, will be substituted with the old and new usernames,
           respectively. The script should return 0 upon successful
           completion, and nonzero otherwise.

           Note
           The script has all responsibility to rename all the necessary data
           that is accessible in this posix method. This can mean different
           requirements for different backends. The tdbsam and smbpasswd
           backends will take care of the contents of their respective files,
           so the script is responsible only for changing the POSIX username,
           and other data that may required for your circumstances, such as
           home directory. Please also consider whether or not you need to
           rename the actual home directories themselves. The ldapsam backend
           will not make any changes, because of the potential issues with
           renaming the LDAP naming attribute. In this case the script is
           responsible for changing the attribute that samba uses (uid) for
           locating users, as well as any data that needs to change for other
           applications using the same directory.

           Default: rename user script = no

       reset on zero vc (G)

           This boolean option controls whether an incoming session setup
           should kill other connections coming from the same IP. This matches
           the default Windows 2003 behaviour. Setting this parameter to yes
           becomes necessary when you have a flaky network and windows decides
           to reconnect while the old connection still has files with share
           modes open. These files become inaccessible over the new
           connection. The client sends a zero VC on the new connection, and
           Windows 2003 kills all other connections coming from the same IP.
           This way the locked files are accessible again. Please be aware
           that enabling this option will kill connections behind a
           masquerading router.

           Default: reset on zero vc = no

       restrict anonymous (G)

           The setting of this parameter determines whether user and group
           list information is returned for an anonymous connection. and
           mirrors the effects of the

               HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
                          Control\LSA\RestrictAnonymous

           registry key in Windows 2000 and Windows NT. When set to 0, user
           and group list information is returned to anyone who asks. When set
           to 1, only an authenticated user can retrive user and group list
           information. For the value 2, supported by Windows 2000/XP and
           Samba, no anonymous connections are allowed at all. This can break
           third party and Microsoft applications which expect to be allowed
           to perform operations anonymously.

           The security advantage of using restrict anonymous = 1 is dubious,
           as user and group list information can be obtained using other
           means.

           Note
           The security advantage of using restrict anonymous = 2 is removed
           by setting guest ok = yes on any share.

           Default: restrict anonymous = 0
       root.PP
           This parameter is a synonym for root directory.
       root dir.PP
           This parameter is a synonym for root directory.

       root directory (G)

           The server will chroot() (i.e. Change its root directory) to this
           directory on startup. This is not strictly necessary for secure
           operation. Even without it the server will deny access to files not
           in one of the service entries. It may also check for, and deny
           access to, soft links to other parts of the filesystem, or attempts
           to use ".." in file names to access other directories (depending on
           the setting of the wide smbconfoptions parameter).

           Adding a root directory entry other than "/" adds an extra level of
           security, but at a price. It absolutely ensures that no access is
           given to files not in the sub-tree specified in the root directory
           option, including some files needed for complete operation of the
           server. To maintain full operability of the server you will need to
           mirror some system files into the root directory tree. In
           particular you will need to mirror /etc/passwd (or a subset of it),
           and any binaries or configuration files needed for printing (if
           required). The set of files that must be mirrored is operating
           system dependent.

           Default: root directory = /

           Example: root directory = /homes/smb

       root postexec (S)

           This is the same as the postexec parameter except that the command
           is run as root. This is useful for unmounting filesystems (such as
           CDROMs) after a connection is closed.

           Default: root postexec =

       root preexec close (S)

           This is the same as the preexec close parameter except that the
           command is run as root.

           Default: root preexec close = no

       root preexec (S)

           This is the same as the preexec parameter except that the command
           is run as root. This is useful for mounting filesystems (such as
           CDROMs) when a connection is opened.

           Default: root preexec =

       security mask (S)

           This parameter controls what UNIX permission bits will be set when
           a Windows NT client is manipulating the UNIX permission on a file
           using the native NT security dialog box.

           This parameter is applied as a mask (AND'ed with) to the incoming
           permission bits, thus resetting any bits not in this mask. Make
           sure not to mix up this parameter with force security mode, which
           works in a manner similar to this one but uses a logical OR instead
           of an AND.

           Essentially, all bits set to zero in this mask will result in
           setting to zero the corresponding bits on the file permissions
           regardless of the previous status of this bits on the file.

           If not set explicitly this parameter is 0777, allowing a user to
           set all the user/group/world permissions on a file.

            Note that users who can access the Samba server through other
           means can easily bypass this restriction, so it is primarily useful
           for standalone "appliance" systems. Administrators of most normal
           systems will probably want to leave it set to 0777.

           Default: security mask = 0777

           Example: security mask = 0770

       security (G)

           This option affects how clients respond to Samba and is one of the
           most important settings in the
            smb.conf file.

           The option sets the "security mode bit" in replies to protocol
           negotiations with smbd(8) to turn share level security on or off.
           Clients decide based on this bit whether (and how) to transfer user
           and password information to the server.

           The default is security = user, as this is the most common setting
           needed when talking to Windows 98 and Windows NT.

           The alternatives are security = share, security = server or
           security = domain.

           In versions of Samba prior to 2.0.0, the default was security =
           share mainly because that was the only option at one stage.

           There is a bug in WfWg that has relevance to this setting. When in
           user or server level security a WfWg client will totally ignore the
           username and password you type in the "connect drive" dialog box.
           This makes it very difficult (if not impossible) to connect to a
           Samba service as anyone except the user that you are logged into
           WfWg as.

           If your PCs use usernames that are the same as their usernames on
           the UNIX machine then you will want to use security = user. If you
           mostly use usernames that don't exist on the UNIX box then use
           security = share.

           You should also use security = share if you want to mainly setup
           shares without a password (guest shares). This is commonly used for
           a shared printer server. It is more difficult to setup guest shares
           with security = user, see the map to guestparameter for details.

           It is possible to use smbd in a
            hybrid mode where it is offers both user and share level security
           under different NetBIOS aliases.

           The different settings will now be explained.

           SECURITY = SHARE

           When clients connect to a share level security server they need not
           log onto the server with a valid username and password before
           attempting to connect to a shared resource (although modern clients
           such as Windows 95/98 and Windows NT will send a logon request with
           a username but no password when talking to a security = share
           server). Instead, the clients send authentication information
           (passwords) on a per-share basis, at the time they attempt to
           connect to that share.

           Note that smbd ALWAYS uses a valid UNIX user to act on behalf of
           the client, even in security = share level security.

           As clients are not required to send a username to the server in
           share level security, smbd uses several techniques to determine the
           correct UNIX user to use on behalf of the client.

           A list of possible UNIX usernames to match with the given client
           password is constructed using the following methods :

           o   If the guest only parameter is set, then all the other stages
               are missed and only the guest account username is checked.

           o   Is a username is sent with the share connection request, then
               this username (after mapping - see username map), is added as a
               potential username.

           o   If the client did a previous logon request (the SessionSetup
               SMB call) then the username sent in this SMB will be added as a
               potential username.

           o   The name of the service the client requested is added as a
               potential username.

           o   The NetBIOS name of the client is added to the list as a
               potential username.

           o   Any users on the user list are added as potential usernames.

           If the guest only parameter is not set, then this list is then
           tried with the supplied password. The first user for whom the
           password matches will be used as the UNIX user.

           If the guest only parameter is set, or no username can be
           determined then if the share is marked as available to the guest
           account, then this guest user will be used, otherwise access is
           denied.

           Note that it can be very confusing in share-level security as to
           which UNIX username will eventually be used in granting access.

           See also the section NOTE ABOUT USERNAME/PASSWORD VALIDATION.

           SECURITY = USER

           This is the default security setting in Samba 3.0. With user-level
           security a client must first "log-on" with a valid username and
           password (which can be mapped using the username map parameter).
           Encrypted passwords (see the encrypted passwords parameter) can
           also be used in this security mode. Parameters such as user and
           guest only if set are then applied and may change the UNIX user to
           use on this connection, but only after the user has been
           successfully authenticated.

           Note that the name of the resource being requested is not sent to
           the server until after the server has successfully authenticated
           the client. This is why guest shares don't work in user level
           security without allowing the server to automatically map unknown
           users into the guest account. See the map to guest parameter for
           details on doing this.

           See also the section NOTE ABOUT USERNAME/PASSWORD VALIDATION.

           SECURITY = DOMAIN

           This mode will only work correctly if smbnet(8) has been used to
           add this machine into a Windows NT Domain. It expects the encrypted
           passwords parameter to be set to yes. In this mode Samba will try
           to validate the username/password by passing it to a Windows NT
           Primary or Backup Domain Controller, in exactly the same way that a
           Windows NT Server would do.

           Note that a valid UNIX user must still exist as well as the account
           on the Domain Controller to allow Samba to have a valid UNIX
           account to map file access to.

           Note that from the client's point of view security = domain is the
           same as security = user. It only affects how the server deals with
           the authentication, it does not in any way affect what the client
           sees.

           Note that the name of the resource being requested is not sent to
           the server until after the server has successfully authenticated
           the client. This is why guest shares don't work in user level
           security without allowing the server to automatically map unknown
           users into the guest account. See the map to guest parameter for
           details on doing this.

           See also the section NOTE ABOUT USERNAME/PASSWORD VALIDATION.

           See also the password server parameter and the encrypted passwords
           parameter.

           SECURITY = SERVER

           In this mode Samba will try to validate the username/password by
           passing it to another SMB server, such as an NT box. If this fails
           it will revert to security = user. It expects the encrypted
           passwords parameter to be set to yes, unless the remote server does
           not support them. However note that if encrypted passwords have
           been negotiated then Samba cannot revert back to checking the UNIX
           password file, it must have a valid smbpasswd file to check users
           against. See the chapter about the User Database in the Samba HOWTO
           Collection for details on how to set this up.

           Note
           This mode of operation has significant pitfalls since it is more
           vulnerable to man-in-the-middle attacks and server impersonation.
           In particular, this mode of operation can cause significant
           resource consuption on the PDC, as it must maintain an active
           connection for the duration of the user's session. Furthermore, if
           this connection is lost, there is no way to reestablish it, and
           futher authentications to the Samba server may fail (from a single
           client, till it disconnects).

           Note
           From the client's point of view security = server is the same as
           security = user. It only affects how the server deals with the
           authentication, it does not in any way affect what the client sees.

           Note that the name of the resource being requested is not sent to
           the server until after the server has successfully authenticated
           the client. This is why guest shares don't work in user level
           security without allowing the server to automatically map unknown
           users into the guest account. See the map to guest parameter for
           details on doing this.

           See also the section NOTE ABOUT USERNAME/PASSWORD VALIDATION.

           See also the password server parameter and the encrypted passwords
           parameter.

           SECURITY = ADS

           In this mode, Samba will act as a domain member in an ADS realm. To
           operate in this mode, the machine running Samba will need to have
           Kerberos installed and configured and Samba will need to be joined
           to the ADS realm using the smbnet utility.

           Note that this mode does NOT make Samba operate as a Active
           Directory Domain Controller.

           Read the chapter about Domain Membership in the HOWTO for details.

           Default: security = USER

           Example: security = DOMAIN

       server schannel (G)

           This controls whether the server offers or even demands the use of
           the netlogon schannel.  server schannel = no does not offer the
           schannel, server schannel = auto offers the schannel but does not
           enforce it, and server schannel = yes denies access if the client
           is not able to speak netlogon schannel. This is only the case for
           Windows NT4 before SP4.

           Please note that with this set to no you will have to apply the
           WindowsXP WinXP_SignOrSeal.reg registry patch found in the
           docs/registry subdirectory of the Samba distribution tarball.

           Default: server schannel = auto

           Example: server schannel = yes

       server signing (G)

           This controls whether the server offers or requires the client it
           talks to to use SMB signing. Possible values are auto, mandatory
           and disabled.

           When set to auto, SMB signing is offered, but not enforced. When
           set to mandatory, SMB signing is required and if set to disabled,
           SMB signing is not offered either.

           Default: server signing = Disabled

       server string (G)

           This controls what string will show up in the printer comment box
           in print manager and next to the IPC connection in smbnet view. It
           can be any string that you wish to show to your users.

           It also sets what will appear in browse lists next to the machine
           name.

           A %v will be replaced with the Samba version number.

           A %h will be replaced with the hostname.

           Default: server string = Samba %v

           Example: server string = University of GNUs Samba Server

       set directory (S)

           If set directory = no, then users of the service may not use the
           setdir command to change directory.

           The setdir command is only implemented in the Digital Pathworks
           client. See the Pathworks documentation for details.

           Default: set directory = no

       set primary group script (G)

           Thanks to the Posix subsystem in NT a Windows User has a primary
           group in addition to the auxiliary groups. This script sets the
           primary group in the unix userdatase when an administrator sets the
           primary group from the windows user manager or when fetching a SAM
           with smbnet rpc vampire.  %u will be replaced with the user whose
           primary group is to be set.  %g will be replaced with the group to
           set.

           Default: set primary group script =

           Example: set primary group script = /usr/sbin/usermod -g '%g' '%u'

       set quota command (G)

           The set quota command should only be used whenever there is no
           operating system API available from the OS that samba can use.

           This option is only available if Samba was configured with the
           argument --with-sys-quotas or on linux when was used and a working
           quota api was found in the system. Most packages are configured
           with these options already.

           This parameter should specify the path to a script that can set
           quota for the specified arguments.

           The specified script should take the following arguments:

           o   1 - quota type

               o   1 - user quotas

               o   2 - user default quotas (uid = -1)

               o   3 - group quotas

               o   4 - group default quotas (gid = -1)

           o   2 - id (uid for user, gid for group, -1 if N/A)

           o   3 - quota state (0 = disable, 1 = enable, 2 = enable and
               enforce)

           o   4 - block softlimit

           o   5 - block hardlimit

           o   6 - inode softlimit

           o   7 - inode hardlimit

           o   8(optional) - block size, defaults to 1024

           The script should output at least one line of data on success. And
           nothing on failure.

           Default: set quota command =

           Example: set quota command = /usr/local/sbin/set_quota

       share modes (S)

           This enables or disables the honoring of the share modes during a
           file open. These modes are used by clients to gain exclusive read
           or write access to a file.

           These open modes are not directly supported by UNIX, so they are
           simulated using shared memory, or lock files if your UNIX doesn't
           support shared memory (almost all do).

           The share modes that are enabled by this option are DENY_DOS,
           DENY_ALL, DENY_READ, DENY_WRITE, DENY_NONE and DENY_FCB.

           This option gives full share compatibility and enabled by default.

           You should NEVER turn this parameter off as many Windows
           applications will break if you do so.

           Default: share modes = yes

       short preserve case (S)

           This boolean parameter controls if new files which conform to 8.3
           syntax, that is all in upper case and of suitable length, are
           created upper case, or if they are forced to be the default case.
           This option can be use with preserve case = yes to permit long
           filenames to retain their case, while short names are lowered.

           See the section on NAME MANGLING.

           Default: short preserve case = yes

       show add printer wizard (G)

           With the introduction of MS-RPC based printing support for Windows
           NT/2000 client in Samba 2.2, a "Printers..." folder will appear on
           Samba hosts in the share listing. Normally this folder will contain
           an icon for the MS Add Printer Wizard (APW). However, it is
           possible to disable this feature regardless of the level of
           privilege of the connected user.

           Under normal circumstances, the Windows NT/2000 client will open a
           handle on the printer server with OpenPrinterEx() asking for
           Administrator privileges. If the user does not have administrative
           access on the print server (i.e is not root or a member of the
           printer admin group), the OpenPrinterEx() call fails and the client
           makes another open call with a request for a lower privilege level.
           This should succeed, however the APW icon will not be displayed.

           Disabling the show add printer wizard parameter will always cause
           the OpenPrinterEx() on the server to fail. Thus the APW icon will
           never be displayed.

           Note
           This does not prevent the same user from having administrative
           privilege on an individual printer.

           Default: show add printer wizard = yes

       shutdown script (G)

           This a full path name to a script called by smbd(8) that should
           start a shutdown procedure.

           If the connected user posseses the SeRemoteShutdownPrivilege,
           right, this command will be run as user.

           The %z %t %r %f variables are expanded as follows:

           o   %z will be substituted with the shutdown message sent to the
               server.

           o   %t will be substituted with the number of seconds to wait
               before effectively starting the shutdown procedure.

           o   %r will be substituted with the switch -r. It means reboot
               after shutdown for NT.

           o   %f will be substituted with the switch -f. It means force the
               shutdown even if applications do not respond for NT.

           Shutdown script example:

               #!/bin/bash

               $time=0
               let "time/60"
               let "time++"

               /sbin/shutdown $3 $4 +$time $1 &

           Shutdown does not return so we need to launch it in background.

           Default: shutdown script =

           Example: shutdown script = /usr/local/samba/sbin/shutdown %m %t %r
           %f

       smb passwd file (G)

           This option sets the path to the encrypted smbpasswd file. By
           default the path to the smbpasswd file is compiled into Samba.

           An example of use is:

               smb passwd file = /etc/samba/smbpasswd

           Default: smb passwd file = ${prefix}/private/smbpasswd

       smb ports (G)

           Specifies which ports the server should listen on for SMB traffic.

           Default: smb ports = 445 139

       socket address (G)

           This option allows you to control what address Samba will listen
           for connections on. This is used to support multiple virtual
           interfaces on the one server, each with a different configuration.

           By default Samba will accept connections on any address.

           Default: socket address =

           Example: socket address = 192.168.2.20

       socket options (G)

           This option allows you to set socket options to be used when
           talking with the client.

           Socket options are controls on the networking layer of the
           operating systems which allow the connection to be tuned.

           This option will typically be used to tune your Samba server for
           optimal performance for your local network. There is no way that
           Samba can know what the optimal parameters are for your net, so you
           must experiment and choose them yourself. We strongly suggest you
           read the appropriate documentation for your operating system first
           (perhaps man setsockopt will help).

           You may find that on some systems Samba will say "Unknown socket
           option" when you supply an option. This means you either
           incorrectly typed it or you need to add an include file to
           includes.h for your OS. If the latter is the case please send the
           patch to samba-technical@samba.org.

           Any of the supported socket options may be combined in any way you
           like, as long as your OS allows it.

           This is the list of socket options currently settable using this
           option:

           o   SO_KEEPALIVE

           o   SO_REUSEADDR

           o   SO_BROADCAST

           o   TCP_NODELAY

           o   IPTOS_LOWDELAY

           o   IPTOS_THROUGHPUT

           o   SO_SNDBUF *

           o   SO_RCVBUF *

           o   SO_SNDLOWAT *

           o   SO_RCVLOWAT *

           Those marked with a '*' take an integer argument. The others can
           optionally take a 1 or 0 argument to enable or disable the option,
           by default they will be enabled if you don't specify 1 or 0.

           To specify an argument use the syntax SOME_OPTION = VALUE for
           example SO_SNDBUF = 8192. Note that you must not have any spaces
           before or after the = sign.

           If you are on a local network then a sensible option might be:

           socket options = IPTOS_LOWDELAY

           If you have a local network then you could try:

           socket options = IPTOS_LOWDELAY TCP_NODELAY

           If you are on a wide area network then perhaps try setting
           IPTOS_THROUGHPUT.

           Note that several of the options may cause your Samba server to
           fail completely. Use these options with caution!

           Default: socket options = TCP_NODELAY

           Example: socket options = IPTOS_LOWDELAY

       stat cache (G)

           This parameter determines if smbd(8) will use a cache in order to
           speed up case insensitive name mappings. You should never need to
           change this parameter.

           Default: stat cache = yes

       store dos attributes (S)

           If this parameter is set Samba attempts to first read DOS
           attributes (SYSTEM, HIDDEN, ARCHIVE or READ-ONLY) from a filesystem
           extended attribute, before mapping DOS attributes to UNIX
           permission bits (such as occurs with map hidden and map readonly).
           When set, DOS attributes will be stored onto an extended attribute
           in the UNIX filesystem, associated with the file or directory. For
           no other mapping to occur as a fall-back, the parameters map
           hidden, map system, map archive and map readonly must be set to
           off. This parameter writes the DOS attributes as a string into the
           extended attribute named "user.DOSATTRIB". This extended attribute
           is explicitly hidden from smbd clients requesting an EA list. On
           Linux the filesystem must have been mounted with the mount option
           user_xattr in order for extended attributes to work, also extended
           attributes must be compiled into the Linux kernel.

           Default: store dos attributes = no

       strict allocate (S)

           This is a boolean that controls the handling of disk space
           allocation in the server. When this is set to yes the server will
           change from UNIX behaviour of not committing real disk storage
           blocks when a file is extended to the Windows behaviour of actually
           forcing the disk system to allocate real storage blocks when a file
           is created or extended to be a given size. In UNIX terminology this
           means that Samba will stop creating sparse files. This can be slow
           on some systems.

           When strict allocate is no the server does sparse disk block
           allocation when a file is extended.

           Setting this to yes can help Samba return out of quota messages on
           systems that are restricting the disk quota of users.

           Default: strict allocate = no

       strict locking (S)

           This is an enumerated type that controls the handling of file
           locking in the server. When this is set to yes, the server will
           check every read and write access for file locks, and deny access
           if locks exist. This can be slow on some systems.

           When strict locking is set to Auto (the default), the server
           performs file lock checks only on non-oplocked files. As most
           Windows redirectors perform file locking checks locally on oplocked
           files this is a good trade off for inproved performance.

           When strict locking is disabled, the server performs file lock
           checks only when the client explicitly asks for them.

           Well-behaved clients always ask for lock checks when it is
           important. So in the vast majority of cases, strict locking = Auto
           or strict locking = no is acceptable.

           Default: strict locking = Auto

       strict sync (S)

           Many Windows applications (including the Windows 98 explorer shell)
           seem to confuse flushing buffer contents to disk with doing a sync
           to disk. Under UNIX, a sync call forces the process to be suspended
           until the kernel has ensured that all outstanding data in kernel
           disk buffers has been safely stored onto stable storage. This is
           very slow and should only be done rarely. Setting this parameter to
           no (the default) means that smbd(8) ignores the Windows
           applications requests for a sync call. There is only a possibility
           of losing data if the operating system itself that Samba is running
           on crashes, so there is little danger in this default setting. In
           addition, this fixes many performance problems that people have
           reported with the new Windows98 explorer shell file copies.

           Default: strict sync = no

       svcctl list (G)

           This option defines a list of init scripts that smbd will use for
           starting and stopping Unix services via the Win32 ServiceControl
           API. This allows Windows administrators to utilize the MS
           Management Console plug-ins to manage a Unix server running Samba.

           The administrator must create a directory name svcctl in Samba's
           $(libdir) and create symbolic links to the init scripts in
           /etc/init.d/. The name of the links must match the names given as
           part of the svcctl list.

           Default: svcctl list =

           Example: svcctl list = cups postfix portmap httpd

       sync always (S)

           This is a boolean parameter that controls whether writes will
           always be written to stable storage before the write call returns.
           If this is no then the server will be guided by the client's
           request in each write call (clients can set a bit indicating that a
           particular write should be synchronous). If this is yes then every
           write will be followed by a fsync() call to ensure the data is
           written to disk. Note that the strict sync parameter must be set to
           yes in order for this parameter to have any affect.

           Default: sync always = no

       syslog only (G)

           If this parameter is set then Samba debug messages are logged into
           the system syslog only, and not to the debug log files. There still
           will be some logging to log.[sn]mbd even if syslog only is enabled.

           Default: syslog only = no

       syslog (G)

           This parameter maps how Samba debug messages are logged onto the
           system syslog logging levels. Samba debug level zero maps onto
           syslog LOG_ERR, debug level one maps onto LOG_WARNING, debug level
           two maps onto LOG_NOTICE, debug level three maps onto LOG_INFO. All
           higher levels are mapped to LOG_DEBUG.

           This parameter sets the threshold for sending messages to syslog.
           Only messages with debug level less than this value will be sent to
           syslog. There still will be some logging to log.[sn]mbd even if
           syslog only is enabled.

           Default: syslog = 1

       template homedir (G)

           When filling out the user information for a Windows NT user, the
           winbindd(8) daemon uses this parameter to fill in the home
           directory for that user. If the string %D is present it is
           substituted with the user's Windows NT domain name. If the string
           %U is present it is substituted with the user's Windows NT user
           name.

           Default: template homedir = /home/%D/%U

       template shell (G)

           When filling out the user information for a Windows NT user, the
           winbindd(8) daemon uses this parameter to fill in the login shell
           for that user.

           No default

       time offset (G)

           This parameter is a setting in minutes to add to the normal GMT to
           local time conversion. This is useful if you are serving a lot of
           PCs that have incorrect daylight saving time handling.

           Default: time offset = 0

           Example: time offset = 60

       time server (G)

           This parameter determines if nmbd(8) advertises itself as a time
           server to Windows clients.

           Default: time server = no

       unix charset (G)

           Specifies the charset the unix machine Samba runs on uses. Samba
           needs to know this in order to be able to convert text to the
           charsets other SMB clients use.

           This is also the charset Samba will use when specifying arguments
           to scripts that it invokes.

           Default: unix charset = UTF8

           Example: unix charset = ASCII

       unix extensions (G)

           This boolean parameter controls whether Samba implments the CIFS
           UNIX extensions, as defined by HP. These extensions enable Samba to
           better serve UNIX CIFS clients by supporting features such as
           symbolic links, hard links, etc... These extensions require a
           similarly enabled client, and are of no current use to Windows
           clients.

           Default: unix extensions = yes

       unix password sync (G)

           This boolean parameter controls whether Samba attempts to
           synchronize the UNIX password with the SMB password when the
           encrypted SMB password in the smbpasswd file is changed. If this is
           set to yes the program specified in the passwd programparameter is
           called AS ROOT - to allow the new UNIX password to be set without
           access to the old UNIX password (as the SMB password change code
           has no access to the old password cleartext, only the new).

           Default: unix password sync = no

       update encrypted (G)

           This boolean parameter allows a user logging on with a plaintext
           password to have their encrypted (hashed) password in the smbpasswd
           file to be updated automatically as they log on. This option allows
           a site to migrate from plaintext password authentication (users
           authenticate with plaintext password over the wire, and are checked
           against a UNIX account atabase) to encrypted password
           authentication (the SMB challenge/response authentication
           mechanism) without forcing all users to re-enter their passwords
           via smbpasswd at the time the change is made. This is a convenience
           option to allow the change over to encrypted passwords to be made
           over a longer period. Once all users have encrypted representations
           of their passwords in the smbpasswd file this parameter should be
           set to no.

           In order for this parameter to be operative the encrypt passwords
           parameter must be set to no. The default value of encrypt passwords
           = Yes. Note: This must be set to no for this update encrypted to
           work.

           Note that even when this parameter is set a user authenticating to
           smbd must still enter a valid password in order to connect
           correctly, and to update their hashed (smbpasswd) passwords.

           Default: update encrypted = no

       use client driver (S)

           This parameter applies only to Windows NT/2000 clients. It has no
           effect on Windows 95/98/ME clients. When serving a printer to
           Windows NT/2000 clients without first installing a valid printer
           driver on the Samba host, the client will be required to install a
           local printer driver. From this point on, the client will treat the
           print as a local printer and not a network printer connection. This
           is much the same behavior that will occur when disable spoolss =
           yes.

           The differentiating factor is that under normal circumstances, the
           NT/2000 client will attempt to open the network printer using
           MS-RPC. The problem is that because the client considers the
           printer to be local, it will attempt to issue the OpenPrinterEx()
           call requesting access rights associated with the logged on user.
           If the user possesses local administator rights but not root
           privilege on the Samba host (often the case), the OpenPrinterEx()
           call will fail. The result is that the client will now display an
           "Access Denied; Unable to connect" message in the printer queue
           window (even though jobs may successfully be printed).

           If this parameter is enabled for a printer, then any attempt to
           open the printer with the PRINTER_ACCESS_ADMINISTER right is mapped
           to PRINTER_ACCESS_USE instead. Thus allowing the OpenPrinterEx()
           call to succeed.  This parameter MUST not be able enabled on a
           print share which has valid print driver installed on the Samba
           server.

           Default: use client driver = no

       use kerberos keytab (G)

           Specifies whether Samba should attempt to maintain service
           principals in the systems keytab file for host/FQDN and cifs/FQDN.

           When you are using the heimdal Kerberos libraries, you must also
           specify the following in /etc/krb5.conf:

               [libdefaults]
               default_keytab_name = FILE:/etc/krb5.keytab

           Default: use kerberos keytab = False

       use mmap (G)

           This global parameter determines if the tdb internals of Samba can
           depend on mmap working correctly on the running system. Samba
           requires a coherent mmap/read-write system memory cache. Currently
           only HPUX does not have such a coherent cache, and so this
           parameter is set to no by default on HPUX. On all other systems
           this parameter should be left alone. This parameter is provided to
           help the Samba developers track down problems with the tdb internal
           code.

           Default: use mmap = yes

       username level (G)

           This option helps Samba to try and 'guess' at the real UNIX
           username, as many DOS clients send an all-uppercase username. By
           default Samba tries all lowercase, followed by the username with
           the first letter capitalized, and fails if the username is not
           found on the UNIX machine.

           If this parameter is set to non-zero the behavior changes. This
           parameter is a number that specifies the number of uppercase
           combinations to try while trying to determine the UNIX user name.
           The higher the number the more combinations will be tried, but the
           slower the discovery of usernames will be. Use this parameter when
           you have strange usernames on your UNIX machine, such as
           AstrangeUser .

           This parameter is needed only on UNIX systems that have case
           sensitive usernames.

           Default: username level = 0

           Example: username level = 5

       username map script (G)

           This script is a mutually exclusive alternative to the username map
           parameter. This parameter specifies and external program or script
           that must accept a single command line option (the username
           transmitted in the authentication request) and return a line line
           on standard output (the name to which the account should mapped).
           In this way, it is possible to store username map tables in an LDAP
           or NIS directory services.

           Default: username map script =

           Example: username map script = /etc/samba/scripts/mapusers.sh

       username map (G)

           This option allows you to specify a file containing a mapping of
           usernames from the clients to the server. This can be used for
           several purposes. The most common is to map usernames that users
           use on DOS or Windows machines to those that the UNIX box uses. The
           other is to map multiple users to a single username so that they
           can more easily share files.

           Please note that for user or share mode security, the username map
           is applied prior to validating the user credentials. Domain member
           servers (domain or ads) apply the username map after the user has
           been successfully authenticated by the domain controller and
           require fully qualified enties in the map table (e.g. biddle =
           DOMAIN\foo).

           The map file is parsed line by line. Each line should contain a
           single UNIX username on the left then a '=' followed by a list of
           usernames on the right. The list of usernames on the right may
           contain names of the form @group in which case they will match any
           UNIX username in that group. The special client name '*' is a
           wildcard and matches any name. Each line of the map file may be up
           to 1023 characters long.

           The file is processed on each line by taking the supplied username
           and comparing it with each username on the right hand side of the
           '=' signs. If the supplied name matches any of the names on the
           right hand side then it is replaced with the name on the left.
           Processing then continues with the next line.

           If any line begins with a '#' or a ';' then it is ignored.

           If any line begins with an '!' then the processing will stop after
           that line if a mapping was done by the line. Otherwise mapping
           continues with every line being processed. Using '!' is most useful
           when you have a wildcard mapping line later in the file.

           For example to map from the name admin or administrator to the UNIX
           name
            root you would use:

               root = admin administrator

           Or to map anyone in the UNIX group system to the UNIX name sys you
           would use:

               sys = @system

           You can have as many mappings as you like in a username map file.

           If your system supports the NIS NETGROUP option then the netgroup
           database is checked before the /etc/group database for matching
           groups.

           You can map Windows usernames that have spaces in them by using
           double quotes around the name. For example:

               tridge = "Andrew Tridgell"

           would map the windows username "Andrew Tridgell" to the unix
           username "tridge".

           The following example would map mary and fred to the unix user sys,
           and map the rest to guest. Note the use of the '!' to tell Samba to
           stop processing if it gets a match on that line:

               !sys = mary fred
               guest = *

           Note that the remapping is applied to all occurrences of usernames.
           Thus if you connect to \\server\fred and fred is remapped to mary
           then you will actually be connecting to \\server\mary and will need
           to supply a password suitable for mary not fred. The only exception
           to this is the username passed to the password server (if you have
           one). The password server will receive whatever username the client
           supplies without modification.

           Also note that no reverse mapping is done. The main effect this has
           is with printing. Users who have been mapped may have trouble
           deleting print jobs as PrintManager under WfWg will think they
           don't own the print job.

           Samba versions prior to 3.0.8 would only support reading the fully
           qualified username (e.g.: DOMAIN\user) from the username map when
           performing a kerberos login from a client. However, when looking up
           a map entry for a user authenticated by NTLM[SSP], only the login
           name would be used for matches. This resulted in inconsistent
           behavior sometimes even on the same server.

           The following functionality is obeyed in version 3.0.8 and later:

           When performing local authentication, the username map is applied
           to the login name before attempting to authenticate the connection.

           When relying upon a external domain controller for validating
           authentication requests, smbd will apply the username map to the
           fully qualified username (i.e.  DOMAIN\user) only after the user
           has been successfully authenticated.

           An example of use is:

               username map = /usr/local/samba/lib/users.map

           Default: username map =  # no username map
       user.PP
           This parameter is a synonym for username.
       users.PP
           This parameter is a synonym for username.

       username (S)

           Multiple users may be specified in a comma-delimited list, in which
           case the supplied password will be tested against each username in
           turn (left to right).

           The username line is needed only when the PC is unable to supply
           its own username. This is the case for the COREPLUS protocol or
           where your users have different WfWg usernames to UNIX usernames.
           In both these cases you may also be better using the
           \\server\share%user syntax instead.

           The username line is not a great solution in many cases as it means
           Samba will try to validate the supplied password against each of
           the usernames in the username line in turn. This is slow and a bad
           idea for lots of users in case of duplicate passwords. You may get
           timeouts or security breaches using this parameter unwisely.

           Samba relies on the underlying UNIX security. This parameter does
           not restrict who can login, it just offers hints to the Samba
           server as to what usernames might correspond to the supplied
           password. Users can login as whoever they please and they will be
           able to do no more damage than if they started a telnet session.
           The daemon runs as the user that they log in as, so they cannot do
           anything that user cannot do.

           To restrict a service to a particular set of users you can use the
           valid users parameter.

           If any of the usernames begin with a '@' then the name will be
           looked up first in the NIS netgroups list (if Samba is compiled
           with netgroup support), followed by a lookup in the UNIX groups
           database and will expand to a list of all users in the group of
           that name.

           If any of the usernames begin with a '+' then the name will be
           looked up only in the UNIX groups database and will expand to a
           list of all users in the group of that name.

           If any of the usernames begin with a '&' then the name will be
           looked up only in the NIS netgroups database (if Samba is compiled
           with netgroup support) and will expand to a list of all users in
           the netgroup group of that name.

           Note that searching though a groups database can take quite some
           time, and some clients may time out during the search.

           See the section NOTE ABOUT USERNAME/PASSWORD VALIDATION for more
           information on how this parameter determines access to the
           services.

           Default: username =  # The guest account if a guest service, else
           <empty string>.

           Example: username = fred, mary, jack, jane, @users, @pcgroup

       usershare allow guests (G)

           This parameter controls whether user defined shares are allowed to
           be accessed by non-authenticated users or not. It is the equivalent
           of allowing people who can create a share the option of setting
           guest ok = yes in a share definition. Due to the security sensitive
           nature of this the default is set to off.

           Default: usershare allow guests = no

       usershare max shares (G)

           This parameter specifies the number of user defined shares that are
           allowed to be created by users belonging to the group owning the
           usershare directory. If set to zero (the default) user defined
           shares are ignored.

           Default: usershare max shares = 0

       usershare owner only (G)

           This parameter controls whether the pathname exported by a user
           defined shares must be owned by the user creating the user defined
           share or not. If set to True (the default) then smbd checks that
           the directory path being shared is owned by the user who owns the
           usershare file defining this share and refuses to create the share
           if not. If set to False then no such check is performed and any
           directory path may be exported regardless of who owns it.

           Default: usershare owner only = True

       usershare path (G)

           This parameter specifies the absolute path of the directory on the
           filesystem used to store the user defined share definition files.
           This directory must be owned by root, and have no access for other,
           and be writable only by the group owner. In addition the "sticky"
           bit must also be set, restricting rename and delete to owners of a
           file (in the same way the /tmp directory is usually configured).
           Members of the group owner of this directory are the users allowed
           to create usershares. If this parameter is undefined then no user
           defined shares are allowed.

           For example, a valid usershare directory might be
           /usr/local/samba/lib/usershares, set up as follows.

                    ls -ld /usr/local/samba/lib/usershares/
                    drwxrwx--T  2 root power_users 4096 2006-05-05 12:27 /usr/local/samba/lib/usershares/

           In this case, only members of the group "power_users" can create
           user defined shares.

           Default: usershare path = NULL

       usershare prefix allow list (G)

           This parameter specifies a list of absolute pathnames the root of
           which are allowed to be exported by user defined share definitions.
           If the pathname exported doesn't start with one of the strings in
           this list the user defined share will not be allowed. This allows
           the Samba administrator to restrict the directories on the system
           that can be exported by user defined shares.

           If there is a "usershare prefix deny list" and also a "usershare
           prefix allow list" the deny list is processed first, followed by
           the allow list, thus leading to the most restrictive
           interpretation.

           Default: usershare prefix allow list = NULL

           Example: usershare prefix allow list = /home /data /space

       usershare prefix deny list (G)

           This parameter specifies a list of absolute pathnames the root of
           which are NOT allowed to be exported by user defined share
           definitions. If the pathname exported starts with one of the
           strings in this list the user defined share will not be allowed.
           Any pathname not starting with one of these strings will be allowed
           to be exported as a usershare. This allows the Samba administrator
           to restrict the directories on the system that can be exported by
           user defined shares.

           If there is a "usershare prefix deny list" and also a "usershare
           prefix allow list" the deny list is processed first, followed by
           the allow list, thus leading to the most restrictive
           interpretation.

           Default: usershare prefix deny list = NULL

           Example: usershare prefix deny list = /etc /dev /private

       usershare template share (G)

           User defined shares only have limited possible parameters such as
           path, guest ok etc. This parameter allows usershares to "cloned"
           from an existing share. If "usershare template share" is set to the
           name of an existing share, then all usershares created have their
           defaults set from the parameters set on this share.

           The target share may be set to be invalid for real file sharing by
           setting the parameter "-valid = False" on the template share
           definition. This causes it not to be seen as a real exported share
           but to be able to be used as a template for usershares.

           Default: usershare template share = NULL

           Example: usershare template share = template_share

       use sendfile (S)

           If this parameter is yes, and the sendfile() system call is
           supported by the underlying operating system, then some SMB read
           calls (mainly ReadAndX and ReadRaw) will use the more efficient
           sendfile system call for files that are exclusively oplocked. This
           may make more efficient use of the system CPU's and cause Samba to
           be faster. Samba automatically turns this off for clients that use
           protocol levels lower than NT LM 0.12 and when it detects a client
           is Windows 9x (using sendfile from Linux will cause these clients
           to fail).

           Default: use sendfile = false

       use spnego (G)

           This variable controls controls whether samba will try to use
           Simple and Protected NEGOciation (as specified by rfc2478) with
           WindowsXP and Windows2000 clients to agree upon an authentication
           mechanism.

           Unless further issues are discovered with our SPNEGO
           implementation, there is no reason this should ever be disabled.

           Default: use spnego = yes

       utmp directory (G)

           This parameter is only available if Samba has been configured and
           compiled with the option --with-utmp. It specifies a directory
           pathname that is used to store the utmp or utmpx files (depending
           on the UNIX system) that record user connections to a Samba server.
           By default this is not set, meaning the system will use whatever
           utmp file the native system is set to use (usually /var/run/utmp on
           Linux).

           Default: utmp directory =  # Determined automatically

           Example: utmp directory = /var/run/utmp

       utmp (G)

           This boolean parameter is only available if Samba has been
           configured and compiled with the option --with-utmp. If set to yes
           then Samba will attempt to add utmp or utmpx records (depending on
           the UNIX system) whenever a connection is made to a Samba server.
           Sites may use this to record the user connecting to a Samba share.

           Due to the requirements of the utmp record, we are required to
           create a unique identifier for the incoming user. Enabling this
           option creates an n^2 algorithm to find this number. This may
           impede performance on large installations.

           Default: utmp = no

       valid users (S)

           This is a list of users that should be allowed to login to this
           service. Names starting with '@', '+' and '&' are interpreted using
           the same rules as described in the invalid users parameter.

           If this is empty (the default) then any user can login. If a
           username is in both this list and the invalid users list then
           access is denied for that user.

           The current servicename is substituted for %S. This is useful in
           the [homes] section.

           Default: valid users =  # No valid users list (anyone can login)

           Example: valid users = greg, @pcusers

       -valid (S)

           This parameter indicates whether a share is valid and thus can be
           used. When this parameter is set to false, the share will be in no
           way visible nor accessible.

           This option should not be used by regular users but might be of
           help to developers. Samba uses this option internally to mark
           shares as deleted.

           Default: -valid = yes

       veto files (S)

           This is a list of files and directories that are neither visible
           nor accessible. Each entry in the list must be separated by a '/',
           which allows spaces to be included in the entry. '*' and '?' can be
           used to specify multiple files or directories as in DOS wildcards.

           Each entry must be a unix path, not a DOS path and must not include
           the unix directory separator '/'.

           Note that the case sensitive option is applicable in vetoing files.

           One feature of the veto files parameter that it is important to be
           aware of is Samba's behaviour when trying to delete a directory. If
           a directory that is to be deleted contains nothing but veto files
           this deletion will fail unless you also set the delete veto files
           parameter to yes.

           Setting this parameter will affect the performance of Samba, as it
           will be forced to check all files and directories for a match as
           they are scanned.

           Examples of use include:

               ; Veto any files containing the word Security,
               ; any ending in .tmp, and any directory containing the
               ; word root.
               veto files = /*Security*/*.tmp/*root*/

               ; Veto the Apple specific files that a NetAtalk server
               ; creates.
               veto files = /.AppleDouble/.bin/.AppleDesktop/Network Trash Folder/

           Default: veto files = No files or directories are vetoed.

       veto oplock files (S)

           This parameter is only valid when the oplocks parameter is turned
           on for a share. It allows the Samba administrator to selectively
           turn off the granting of oplocks on selected files that match a
           wildcarded list, similar to the wildcarded list used in the veto
           files parameter.

           You might want to do this on files that you know will be heavily
           contended for by clients. A good example of this is in the NetBench
           SMB benchmark program, which causes heavy client contention for
           files ending in .SEM. To cause Samba not to grant oplocks on these
           files you would use the line (either in the [global] section or in
           the section for the particular NetBench share.

           An example of use is:

               veto oplock files = /.*SEM/

           Default: veto oplock files =  # No files are vetoed for oplock
           grants
       vfs object.PP
           This parameter is a synonym for vfs objects.

       vfs objects (S)

           This parameter specifies the backend names which are used for Samba
           VFS I/O operations. By default, normal disk I/O operations are used
           but these can be overloaded with one or more VFS objects.

           Default: vfs objects =

           Example: vfs objects = extd_audit recycle

       volume (S)

           This allows you to override the volume label returned for a share.
           Useful for CDROMs with installation programs that insist on a
           particular volume label.

           Default: volume =  # the name of the share

       wide links (S)

           This parameter controls whether or not links in the UNIX file
           system may be followed by the server. Links that point to areas
           within the directory tree exported by the server are always
           allowed; this parameter controls access only to areas that are
           outside the directory tree being exported.

           Note that setting this parameter can have a negative effect on your
           server performance due to the extra system calls that Samba has to
           do in order to perform the link checks.

           Default: wide links = yes

       winbind cache time (G)

           This parameter specifies the number of seconds the winbindd(8)
           daemon will cache user and group information before querying a
           Windows NT server again.

           This does not apply to authentication requests, these are always
           evaluated in real time unless the winbind offline logon option has
           been enabled.

           Default: winbind cache time = 300

       winbind enum groups (G)

           On large installations using winbindd(8) it may be necessary to
           suppress the enumeration of groups through the setgrent(),
           getgrent() and endgrent() group of system calls. If the winbind
           enum groups parameter is no, calls to the getgrent() system call
           will not return any data.

           Warning
           Turning off group enumeration may cause some programs to behave
           oddly.

           Default: winbind enum groups = no

       winbind enum users (G)

           On large installations using winbindd(8) it may be necessary to
           suppress the enumeration of users through the setpwent(),
           getpwent() and endpwent() group of system calls. If the winbind
           enum users parameter is no, calls to the getpwent system call will
           not return any data.

           Warning
           Turning off user enumeration may cause some programs to behave
           oddly. For example, the finger program relies on having access to
           the full user list when searching for matching usernames.

           Default: winbind enum users = no

       winbind nested groups (G)

           If set to yes, this parameter activates the support for nested
           groups. Nested groups are also called local groups or aliases. They
           work like their counterparts in Windows: Nested groups are defined
           locally on any machine (they are shared between DC's through their
           SAM) and can contain users and global groups from any trusted SAM.
           To be able to use nested groups, you need to run nss_winbind.

           Default: winbind nested groups = yes

       winbind normalize names (G)

           This parameter controls whether winbindd will replace whitespace in
           user and group names with an underscore (_) character. For example,
           whether the name "Space Kadet" should be replaced with the string
           "space_kadet". Frequently Unix shell scripts will have difficulty
           with usernames contains whitespace due to the default field
           separator in the shell. Do not enable this option if the underscore
           character is used in account names within your domain

           Default: winbind normalize names = no

           Example: winbind normalize names = yes

       winbind nss info (G)

           This parameter is designed to control how Winbind retrieves Name
           Service Information to construct a user's home directory and login
           shell. Currently the following settings are available:

           o   template - The default, using the parameters of template shell
               and template homedir)

           o   <sfu | rfc2307 > - When Samba is running in security = ads and
               your Active Directory Domain Controller does support the
               Microsoft "Services for Unix" (SFU) LDAP schema, winbind can
               retrieve the login shell and the home directory attributes
               directly from your Directory Server. Note that retrieving UID
               and GID from your ADS-Server requires to use idmap backend = ad
               or idmap config DOMAIN:backend = ad as well.

           Default: winbind nss info = template

           Example: winbind nss info = template sfu

       winbind offline logon (G)

           This parameter is designed to control whether Winbind should allow
           to login with the pam_winbind module using Cached Credentials. If
           enabled, winbindd will store user credentials from successful
           logins encrypted in a local cache.

           Default: winbind offline logon = false

           Example: winbind offline logon = true

       winbind refresh tickets (G)

           This parameter is designed to control whether Winbind should
           refresh Kerberos Tickets retrieved using the pam_winbind module.

           Default: winbind refresh tickets = false

           Example: winbind refresh tickets = true

       winbind separator (G)

           This parameter allows an admin to define the character used when
           listing a username of the form of DOMAIN \user. This parameter is
           only applicable when using the pam_winbind.so and nss_winbind.so
           modules for UNIX services.

           Please note that setting this parameter to + causes problems with
           group membership at least on glibc systems, as the character + is
           used as a special character for NIS in /etc/group.

           Default: winbind separator = '\'

           Example: winbind separator = +

       winbind trusted domains only (G)

           This parameter is designed to allow Samba servers that are members
           of a Samba controlled domain to use UNIX accounts distributed via
           NIS, rsync, or LDAP as the uid's for winbindd users in the hosts
           primary domain. Therefore, the user DOMAIN\user1 would be mapped to
           the account user1 in /etc/passwd instead of allocating a new uid
           for him or her.

           This parameter is now deprecated in favor of the newer idmap_nss
           backend. Refer to the idmap domains smb.conf option and the
           idmap_nss(8) man page for more information.

           Default: winbind trusted domains only = no

       winbind use default domain (G)

           This parameter specifies whether the winbindd(8) daemon should
           operate on users without domain component in their username. Users
           without a domain component are treated as is part of the winbindd
           server's own domain. While this does not benifit Windows users, it
           makes SSH, FTP and e-mail function in a way much closer to the way
           they would in a native unix system.

           Default: winbind use default domain = no

           Example: winbind use default domain = yes

       wins hook (G)

           When Samba is running as a WINS server this allows you to call an
           external program for all changes to the WINS database. The primary
           use for this option is to allow the dynamic update of external name
           resolution databases such as dynamic DNS.

           The wins hook parameter specifies the name of a script or
           executable that will be called as follows:

           wins_hook operation name nametype ttl IP_list

           o   The first argument is the operation and is one of "add",
               "delete", or "refresh". In most cases the operation can be
               ignored as the rest of the parameters provide sufficient
               information. Note that "refresh" may sometimes be called when
               the name has not previously been added, in that case it should
               be treated as an add.

           o   The second argument is the NetBIOS name. If the name is not a
               legal name then the wins hook is not called. Legal names
               contain only letters, digits, hyphens, underscores and periods.

           o   The third argument is the NetBIOS name type as a 2 digit
               hexadecimal number.

           o   The fourth argument is the TTL (time to live) for the name in
               seconds.

           o   The fifth and subsequent arguments are the IP addresses
               currently registered for that name. If this list is empty then
               the name should be deleted.

           An example script that calls the BIND dynamic DNS update program
           nsupdate is provided in the examples directory of the Samba source
           code.

           No default

       wins proxy (G)

           This is a boolean that controls if nmbd(8) will respond to
           broadcast name queries on behalf of other hosts. You may need to
           set this to yes for some older clients.

           Default: wins proxy = no

       wins server (G)

           This specifies the IP address (or DNS name: IP address for
           preference) of the WINS server that nmbd(8) should register with.
           If you have a WINS server on your network then you should set this
           to the WINS server's IP.

           You should point this at your WINS server if you have a
           multi-subnetted network.

           If you want to work in multiple namespaces, you can give every wins
           server a 'tag'. For each tag, only one (working) server will be
           queried for a name. The tag should be separated from the ip address
           by a colon.

           Note
           You need to set up Samba to point to a WINS server if you have
           multiple subnets and wish cross-subnet browsing to work correctly.

           See the chapter in the Samba3-HOWTO on Network Browsing.

           Default: wins server =

           Example: wins server = mary:192.9.200.1 fred:192.168.3.199
           mary:192.168.2.61 # For this example when querying a certain name,
           192.19.200.1 will be asked first and if that doesn't respond
           192.168.2.61. If either of those doesn't know the name
           192.168.3.199 will be queried.

           Example: wins server = 192.9.200.1 192.168.2.61

       wins support (G)

           This boolean controls if the nmbd(8) process in Samba will act as a
           WINS server. You should not set this to yes unless you have a
           multi-subnetted network and you wish a particular nmbd to be your
           WINS server. Note that you should NEVER set this to yes on more
           than one machine in your network.

           Default: wins support = no

       workgroup (G)

           This controls what workgroup your server will appear to be in when
           queried by clients. Note that this parameter also controls the
           Domain name used with the security = domain setting.

           Default: workgroup = WORKGROUP

           Example: workgroup = MYGROUP
       writable.PP
           This parameter is a synonym for writeable.

       writeable (S)

           Inverted synonym for read only.

           No default

       write cache size (S)

           If this integer parameter is set to non-zero value, Samba will
           create an in-memory cache for each oplocked file (it does not do
           this for non-oplocked files). All writes that the client does not
           request to be flushed directly to disk will be stored in this cache
           if possible. The cache is flushed onto disk when a write comes in
           whose offset would not fit into the cache or when the file is
           closed by the client. Reads for the file are also served from this
           cache if the data is stored within it.

           This cache allows Samba to batch client writes into a more
           efficient write size for RAID disks (i.e. writes may be tuned to be
           the RAID stripe size) and can improve performance on systems where
           the disk subsystem is a bottleneck but there is free memory for
           userspace programs.

           The integer parameter specifies the size of this cache (per
           oplocked file) in bytes.

           Default: write cache size = 0

           Example: write cache size = 262144 # for a 256k cache size per file

       write list (S)

           This is a list of users that are given read-write access to a
           service. If the connecting user is in this list then they will be
           given write access, no matter what the read only option is set to.
           The list can include group names using the @group syntax.

           Note that if a user is in both the read list and the write list
           then they will be given write access.

           By design, this parameter will not work with the security = share
           in Samba 3.0.

           Default: write list =

           Example: write list = admin, root, @staff

       write raw (G)

           This parameter controls whether or not the server will support raw
           write SMB's when transferring data from clients. You should never
           need to change this parameter.

           Default: write raw = yes

       wtmp directory (G)

           This parameter is only available if Samba has been configured and
           compiled with the option --with-utmp. It specifies a directory
           pathname that is used to store the wtmp or wtmpx files (depending
           on the UNIX system) that record user connections to a Samba server.
           The difference with the utmp directory is the fact that user info
           is kept after a user has logged out.

           By default this is not set, meaning the system will use whatever
           utmp file the native system is set to use (usually /var/run/wtmp on
           Linux).

           Default: wtmp directory =

           Example: wtmp directory = /var/log/wtmp


WARNINGS

       Although the configuration file permits service names to contain
       spaces, your client software may not. Spaces will be ignored in
       comparisons anyway, so it shouldn't be a problem - but be aware of the
       possibility.

       On a similar note, many clients - especially DOS clients - limit
       service names to eight characters.  smbd(8) has no such limitation, but
       attempts to connect from such clients will fail if they truncate the
       service names. For this reason you should probably keep your service
       names down to eight characters in length.

       Use of the [homes] and [printers] special sections make life for an
       administrator easy, but the various combinations of default attributes
       can be tricky. Take extreme care when designing these sections. In
       particular, ensure that the permissions on spool directories are
       correct.
