6 slapo\-memberof \- Reverse Group Membership overlay to slapd
14 allows automatic reverse group membership maintenance.
15 Any time a group entry is modified, its members are modified as appropriate
16 in order to keep a DN-valued "is member of" attribute updated with the DN
20 The config directives that are specific to the
22 overlay must be prefixed by
24 to avoid potential conflicts with directives specific to the underlying
25 database or to other stacked overlays.
29 This directive adds the memberof overlay to the current database; see
36 configuration options are defined for the memberof overlay.
39 .BI memberof\-group\-oc \ <group-oc>
42 is the name of the objectClass that triggers the reverse group membership
44 It defaults to \fIgroupOfNames\fP.
47 .BI memberof\-member\-ad \ <member-ad>
50 is the name of the attribute that contains the names of the members
51 in the group objects; it must be DN-valued.
52 It defaults to \fImember\fP.
55 .BI memberof\-memberof\-ad \ <memberof-ad>
58 is the name of the attribute that contains the names of the groups
59 an entry is member of; it must be DN-valued. Its contents are
60 automatically updated by the overlay.
61 It defaults to \fImemberOf\fP.
64 .BI memberof\-dn \ <dn>
67 contains the DN that is used as \fImodifiersName\fP for internal
68 modifications performed to update the reverse group membership.
69 It defaults to the \fIrootdn\fP of the underlying database.
72 .BI "memberof\-dangling {" ignore ", " drop ", " error "}"
73 This option determines the behavior of the overlay when, during
74 a modification, it encounters dangling references.
77 which may leave dangling references.
80 which discards those modifications that would result in dangling
83 which causes modifications that would result in dangling references
87 .BI memberof\-dangling\-error \ <error-code>
89 .BR memberof\-dangling
92 this configuration parameter can be used to modify the response code
93 returned in case of violation. It defaults to "constraint violation",
94 but other implementations are known to return "no such object" instead.
97 .BI "memberof\-refint {" true "|" FALSE "}"
98 This option determines whether the overlay will try to preserve
99 referential integrity or not.
102 when an entry containing values of the "is member of" attribute is modified,
103 the corresponding groups are modified as well.
106 The memberof overlay may be used with any backend that provides full
107 read-write functionality, but it is mainly intended for use
108 with local storage backends. The maintenance operations it performs
109 are internal to the server on which the overlay is configured and
110 are never replicated. Replica servers should be configured with their
111 own instances of the memberOf overlay if it is desired to maintain
112 these memberOf attributes on the replicas.
