slapindex - Reindex entries in a SLAPD database


       /usr/sbin/slapindex  [-b suffix]  [-c] [-d debug-level] [-f slapd.conf]
       [-F confdir]  [-g]  [-n dbnum]  [-o option[=value]]  [-q]   [-t]   [-v]


       Slapindex is used to regenerate slapd(8) indices based upon the current
       contents of a database.  It opens the given database determined by  the
       database number or suffix and updates the indices for all values of all
       attributes of all entries. If a list of specific attributes is provided
       on  the  command  line,  only  the indices for those attributes will be
       regenerated.  Databases configured as subordinate of this one are  also
       re-indexed, unless -g is specified.

       All  files  eventually created by slapindex will belong to the identity
       slapindex is run as, so make sure you either  run  slapindex  with  the
       same  identity  slapd(8) will be run as (see option -u in slapd(8)), or
       change file ownership before running slapd(8).


       -b suffix
              Use the specified suffix to determine which database to generate
              output  for.   The  -b cannot be used in conjunction with the -n

       -c     enable continue (ignore errors) mode.

       -d debug-level
              enable debugging messages as defined  by  the  specified  debug-
              level; see slapd(8) for details.

       -f slapd.conf
              specify an alternative slapd.conf(5) file.

       -F confdir
              specify  a  config  directory.  If both -f and -F are specified,
              the config file will be read and converted to  config  directory
              format  and  written  to  the  specified  directory.  If neither
              option is specified, an  attempt  to  read  the  default  config
              directory  will  be made before trying to use the default config
              file. If a valid config directory exists then the default config
              file is ignored.

       -g     disable subordinate gluing.  Only the specified database will be
              processed, and not its glued subordinates (if any).

       -n dbnum
              Generate output for the dbnum-th database listed in the configu-
              ration  file. The config database slapd-config(5), is always the
              first database, so use -n 0

              The -n cannot be used in conjunction with the -b option.

       -o option[=value]
              Specify an option with a(n optional)  value.   Possible  generic
              options/values are:

                     syslog=<subsystems>  (see `-s' in slapd(8))
                     syslog-level=<level> (see `-S' in slapd(8))
                     syslog-user=<user>   (see `-l' in slapd(8))

       -q     enable  quick (fewer integrity checks) mode. Performs no consis-
              tency checks when writing the database. Improves indexing  time,
              however  the database will most likely be unusable if any errors
              or interruptions occur.

       -t     enable truncate mode.  Truncates  (empties)  an  index  database
              before indexing any entries. May only be used with Quick mode.

       -v     enable verbose mode.


       Your  slapd(8) should not be running (at least, not in read-write mode)
       when you do this to ensure consistency of the database.

       To reindex your SLAPD database, give the command:

       To regenerate the index for only a specific attribute, e.g. "uid", give
       the command:

            /usr/sbin/slapindex uid


       ldap(3), ldif(5), slapadd(8), ldapadd(1), slapd(8)
