slapo-refint(5)

NAME

       slapo-refint - Referential Integrity overlay to slapd

SYNOPSIS

       /etc/openldap/slapd.conf

DESCRIPTION

       The  Referential  Integrity overlay can be used with a backend database
       such as slapd-bdb(5) to maintain the cohesiveness  of  a  schema  which
       utilizes reference attributes.

       Integrity  is maintained by updating database records which contain the
       named attributes to match the results of a modrdn or delete  operation.
       For  example,  if  the  integrity attribute were configured as manager,
       deletion of the record  "uid=robert,ou=people,dc=example,dc=com"  would
       trigger  a  search for all other records which have a manager attribute
       containing that DN. Entries matching that search would have their  man-
       ager   attribute   removed.    Or,   renaming   the  same  record  into
       "uid=george,ou=people,dc=example,dc=com" would trigger a search for all
       other  records  which  have  a  manager  attribute  containing that DN.
       Entries matching that search would have their manager attribute deleted
       and replaced by the new DN.

       rootdn must be set for the database.  refint runs as the rootdn to gain
       access to make its updates.  rootpw is not needed.

CONFIGURATION

       These slapd.conf options apply to the  Referential  Integrity  overlay.
       They should appear after the overlay directive.

       refint_attributes <attribute> [...]
              Specify one or more attributes for which integrity will be main-
              tained as described above.

       refint_nothing <string>
              Specify an arbitrary value to be used as a placeholder when  the
              last  value  would  otherwise be deleted from an attribute. This
              can be useful in cases where the schema requires  the  existence
              of an attribute for which referential integrity is enforced. The
              attempted deletion of a required attribute will otherwise result
              in  an Object Class Violation, causing the request to fail.  The
              string must be a valid DN.

       refint_modifiersname <DN>
              Specify the DN to be used as the modifiersName of  the  internal
              modifications performed by the overlay.  It defaults to "cn=Ref-
              erential Integrity Overlay".

       Modifications performed by  this  overlay  are  not  propagated  during
       replication. This overlay must be configured identically on replication
       consumers in order to maintain full synchronization with the provider.
