SLAPO-REFINT(5) File Formats Manual SLAPO-REFINT(5) NAME slapo-refint - Referential Integrity overlay to slapd SYNOPSIS /usr/local/etc/openldap/slapd.conf DESCRIPTION The Referential Integrity overlay can be used with a backend database such as slapd-mdb(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 ac- cess 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 use- ful 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 Vi- olation, 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 modi- fications performed by the overlay. It defaults to "cn=Referential Integrity Overlay". Modifications performed by this overlay are not propagated during replica- tion. This overlay must be configured identically on replication consumers in order to maintain full synchronization with the provider.
