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" at‐
15 tribute updated with the DN of the group.
16 Note that this overlay is deprecated and support will be dropped in fu‐
18 ture OpenLDAP releases. Installations should use the dynlist overlay
19 instead. Using this overlay in a replicated environment is especially
20 discouraged.
21
24 The config directives that are specific to the memberof overlay must be
25 prefixed by memberof-, to avoid potential conflicts with directives
26 specific to the underlying database or to other stacked overlays.
27 overlay memberof
30 This directive adds the memberof overlay to the current data‐
31 base; see slapd.conf(5) for details.
32 The following slapd.conf configuration options are defined for the mem‐
35 berof overlay.
36 memberof-group-oc <group-oc>
39 The value <group-oc> is the name of the objectClass that trig‐
40 gers the reverse group membership update. It defaults to
41 groupOfNames.
42 memberof-member-ad <member-ad>
45 The value <member-ad> is the name of the attribute that contains
46 the names of the members in the group objects; it must be DN-
47 valued. It defaults to member.
48 memberof-memberof-ad <memberof-ad>
51 The value <memberof-ad> is the name of the attribute that con‐
52 tains the names of the groups an entry is member of; it must be
53 DN-valued. Its contents are automatically updated by the over‐
54 lay. It defaults to memberOf.
55 memberof-dn <dn>
58 The value <dn> contains the DN that is used as modifiersName for
59 internal modifications performed to update the reverse group
60 membership. It defaults to the rootdn of the underlying data‐
61 base.
62 memberof-dangling {ignore, drop, error}
65 This option determines the behavior of the overlay when, during
66 a modification, it encounters dangling references. The default
67 is ignore, which may leave dangling references. Other options
68 are drop, which discards those modifications that would result
69 in dangling references, and error, which causes modifications
70 that would result in dangling references to fail.
71 memberof-dangling-error <error-code>
74 If memberof-dangling is set to error, this configuration parame‐
75 ter can be used to modify the response code returned in case of
76 violation. It defaults to "constraint violation", but other im‐
77 plementations are known to return "no such object" instead.
78 memberof-refint {true|FALSE}
81 This option determines whether the overlay will try to preserve
82 referential integrity or not. If set to TRUE, when an entry
83 containing values of the "is member of" attribute is modified,
84 the corresponding groups are modified as well.
85 The memberof overlay may be used with any backend that provides full
88 read-write functionality, but it is mainly intended for use with local
89 storage backends. The maintenance operations it performs are internal
90 to the server on which the overlay is configured and are never repli‐
91 cated. Consumer servers should be configured with their own instances
92 of the memberOf overlay if it is desired to maintain these memberOf at‐
93 tributes on the consumers. Note that slapo-memberOf is not compatible
94 with syncrepl based replication, and should not be used in a replicated
95 environment. An alternative is to use slapo-dynlist to emulate slapo-
96 memberOf behavior.

104 The memberof overlay has been reworked with the 2.5 release to use a
105 consistent namespace as with other overlays. As a side-effect the fol‐
106 lowing cn=config parameters are deprecated and will be removed in a fu‐
107 ture release: olcMemberOf is replaced with olcMemberOfConfig
108
110 slapo-dynlist(5), slapd.conf(5), slapd-config(5), slapd(8). The
111 slapo-memberof(5) overlay supports dynamic configuration via back-con‐
112 fig.
