6 slapo\-refint \- Referential Integrity overlay to slapd
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,dc=example,dc=com" would trigger a
22 search for all other records which have a
24 attribute containing that DN. Entries matching that search would have their
27 Or, renaming the same record into "uid=george,ou=people,dc=example,dc=com"
28 would trigger a search for all other records which have a
30 attribute containing that DN.
31 Entries matching that search would have their
33 attribute deleted and replaced by the new DN.
36 must be set for the database. refint runs as the rootdn
37 to gain access to make its updates.
43 options apply to the Referential Integrity overlay.
44 They should appear after the
48 .B refint_attributes <attribute> [...]
49 Specify one or more attributes for which integrity will be maintained
52 .B refint_nothing <string>
53 Specify an arbitrary value to be used as a placeholder when the last value
54 would otherwise be deleted from an attribute. This can be useful in cases
55 where the schema requires the existence of an attribute for which referential
56 integrity is enforced. The attempted deletion of a required attribute will
57 otherwise result in an Object Class Violation, causing the request to fail.
58 The string must be a valid DN.
60 .B refint_modifiersname <DN>
61 Specify the DN to be used as the modifiersName of the internal modifications
62 performed by the overlay.
63 It defaults to "\fIcn=Referential Integrity Overlay\fP".
65 Modifications performed by this overlay are not propagated during
66 replication. This overlay must be configured identically on
67 replication consumers in order to maintain full synchronization
