6 slapo-memberof - Reverse Group Membership overlay to slapd
7
9 /etc/openldap/slapd.conf
10
12 The memberof overlay to slapd(8) allows automatic reverse group member‐
13 ship maintenance. Any time a group entry is modified, its members are
14 modified as appropriate in order to keep a DN-valued "is member of"
15 attribute updated with the DN of the group.
16
19 The config directives that are specific to the memberof overlay must be
20 prefixed by memberof-, to avoid potential conflicts with directives
21 specific to the underlying database or to other stacked overlays.
22 overlay memberof
25 This directive adds the memberof overlay to the current data‐
26 base; see slapd.conf(5) for details.
27 The following slapd.conf configuration options are defined for the mem‐
30 berof overlay.
31 memberof-group-oc <group-oc>
34 The value <group-oc> is the name of the objectClass that trig‐
35 gers the reverse group membership update. It defaults to
36 groupOfNames.
37 memberof-member-ad <member-ad>
40 The value <member-ad> is the name of the attribute that contains
41 the names of the members in the group objects; it must be DN-
42 valued. It defaults to member.
43 memberof-memberof-ad <memberof-ad>
46 The value <memberof-ad> is the name of the attribute that con‐
47 tains the names of the groups an entry is member of; it must be
48 DN-valued. Its contents are automatically updated by the over‐
49 lay. It defaults to memberOf.
50 memberof-dn <dn>
53 The value <dn> contains the DN that is used as modifiersName for
54 internal modifications performed to update the reverse group
55 membership. It defaults to the rootdn of the underlying data‐
56 base.
57 memberof-dangling {ignore, drop, error}
60 This option determines the behavior of the overlay when, during
61 a modification, it encounters dangling references. The default
62 is ignore, which may leave dangling references. Other options
63 are drop, which discards those modifications that would result
64 in dangling references, and error, which causes modifications
65 that would result in dangling references to fail.
66 memberof-dangling-error <error-code>
69 If memberof-dangling is set to error, this configuration parame‐
70 ter can be used to modify the response code returned in case of
71 violation. It defaults to "constraint violation", but other
72 implementations are known to return "no such object" instead.
73 memberof-refint {true|FALSE}
76 This option determines whether the overlay will try to preserve
77 referential integrity or not. If set to TRUE, when an entry
78 containing values of the "is member of" attribute is modified,
79 the corresponding groups are modified as well.
80 The memberof overlay may be used with any backend that provides full
83 read-write functionality, but it is mainly intended for use with local
84 storage backends. The maintenance operations it performs are internal
85 to the server on which the overlay is configured and are never repli‐
86 cated. Replica servers should be configured with their own instances of
87 the memberOf overlay if it is desired to maintain these memberOf
88 attributes on the replicas. Note that slapo-memberOf is not compatible
89 with syncrepl based replication, and should not be used in a replicated
90 environment. An alternative is to use slapo-dynlist to emulate slapo-
91 memberOf behavior.
