slapo-refint - Referential Integrity overlay to slapd
ETCDIR/slapd.conf
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.
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.
