NAME

6       slapo-refint - Referential Integrity overlay
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,o=openldap.org"  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.
23

CONFIGURATION

25       These  slapd.conf  options  apply to the Referential Integrity overlay.
26       They should appear after the overlay directive.
27
28       refint_attributes <attribute...>
29              Specify one or more attributes for which integrity will be main‐
30              tained as described above.
31
32       refint_nothing <string>
33              Specify  an arbitrary value to be used as a placeholder when the
34              last value would otherwise be deleted from  an  attribute.  This
35              can  be  useful in cases where the schema requires the existence
36              of an attribute for which referential integrity is enforced. The
37              attempted deletion of a required attribute will otherwise result
38              in an Object Class Violation, causing the request to fail.
