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  opera-
       tion.  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.

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 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=Referen-
	      tial Integrity Overlay".
