NAME

     slapo-refint - Referential Integrity overlay

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,o=openldap.org" would trigger a search
     for  all  other  records which have a manager attribute con-
     taining that DN. Entries matching  that  search  would  have
     their manager attribute removed.

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  dele-
          tion  of  a required attribute will otherwise result in
          an Object Class Violation, causing the request to fail.
