NAME

6       slapo-refint - Referential Integrity overlay to slapd
7

SYNOPSIS

9       /etc/openldap/slapd.conf
10

DESCRIPTION

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.

CONFIGURATION

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".
