6 slapo-refint - Referential Integrity overlay to slapd
7
9 /etc/openldap/slapd.conf
10
12 The Referential Integrity overlay can be used with a backend database
13 such as slapd-bdb(5) to maintain the cohesiveness of a schema which
14 utilizes reference attributes.
15
16 Integrity is maintained by updating database records which contain the
17 named attributes to match the results of a modrdn or delete operation.
18 For example, if the integrity attribute were configured as manager,
19 deletion of the record "uid=robert,ou=people,dc=example,dc=com" would
20 trigger a search for all other records which have a manager attribute
21 containing that DN. Entries matching that search would have their man‐
22 ager attribute removed. Or, renaming the same record into
23 "uid=george,ou=people,dc=example,dc=com" would trigger a search for all
24 other records which have a manager attribute containing that DN.
25 Entries matching that search would have their manager attribute deleted
26 and replaced by the new DN.
27
29 These slapd.conf options apply to the Referential Integrity overlay.
30 They should appear after the overlay directive.
31
32 refint_attributes <attribute> [...]
33 Specify one or more attributes for which integrity will be main‐
34 tained as described above.
35
36 refint_nothing <string>
37 Specify an arbitrary value to be used as a placeholder when the
38 last value would otherwise be deleted from an attribute. This
39 can be useful in cases where the schema requires the existence
40 of an attribute for which referential integrity is enforced. The
41 attempted deletion of a required attribute will otherwise result
42 in an Object Class Violation, causing the request to fail. The
43 string must be a valid DN.
44
45 refint_modifiersname <DN>
46 Specify the DN to be used as the modifiersName of the internal
47 modifications performed by the overlay. It defaults to "cn=Ref‐
48 erential Integrity Overlay".
