SLAPO-REFINT(5)              File Formats Manual             SLAPO-REFINT(5)

NAME         top

       slapo-refint - Referential Integrity overlay to slapd

SYNOPSIS         top

       ETCDIR/slapd.conf

DESCRIPTION         top

       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 manager 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         top

       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
              maintained 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=Referential 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.
