6 slapo-refint \- Referential Integrity overlay
10 The Referential Integrity overlay can be used with a backend database such as
12 to maintain the cohesiveness of a schema which utilizes reference attributes.
14 Integrity is maintained by updating database records which contain the named
15 attributes to match the results of a
19 operation. For example, if the integrity attribute were configured as
21 deletion of the record "uid=robert,ou=people,o=openldap.org" would trigger a
22 search for all other records which have a
24 attribute containing that DN. Entries matching that search would have their
30 options apply to the Referential Integrity overlay.
31 They should appear after the
33 directive and before any subsequent
37 .B refint_attributes <attribute...>
38 Specify one or more attributes for which integrity will be maintained
41 .B refint_nothing <string>
42 Specify an arbitrary value to be used as a placeholder when the last value
43 would otherwise be deleted from an attribute. This can be useful in cases
44 where the schema requires the existence of an attribute for which referential
45 integrity is enforced. The attempted deletion of a required attribute will
46 otherwise result in an Object Class Violation, causing the request to fail.
