6 slapd.overlays \- overlays for slapd, the stand-alone LDAP daemon
10 daemon can use a variety of different overlays to alter or extend
11 the normal behavior of a database backend.
12 Overlays may be compiled statically into slapd, or when module support
13 is enabled, they may be dynamically loaded. Most of the overlays
14 are only allowed to be configured on individual databases, but some
15 may also be configured globally.
17 Configuration options for each overlay are documented separately in the
19 .BR slapo-<overlay> (5)
24 This overlay can record accesses to a given backend database on another
29 This overlay records changes on a given backend database to an LDIF log
31 By default it is not built.
35 This overlay allows automatic referral chasing when a referral would
36 have been returned, either when configured by the server or when
37 requested by the client.
41 This overlay enforces a regular expression constraint on all values
42 of specified attributes. It is used to enforce a more rigorous
43 syntax when the underlying attribute syntax is too general.
46 Dynamic Directory Services.
47 This overlay supports dynamic objects, which have a limited life after
48 which they expire and are automatically deleted.
52 This is a demo overlay which extends the Compare operation to detect
53 members of a dynamic group.
54 It has no effect on any other operations.
58 This overlay allows expansion of dynamic groups and more.
62 This overlay allows caching of LDAP search requests in a local database.
63 It is most often used with the
71 This overlay provides a variety of password control mechanisms,
72 e.g. password aging, password reuse and duplication control, mandatory
76 Referential Integrity.
77 This overlay can be used with a backend database such as
79 to maintain the cohesiveness of a schema which utilizes reference
84 This overlay is useful to test the behavior of clients when
85 server-generated erroneous and/or unusual responses occur.
89 This overlay is experimental.
90 It performs basic DN/data rewrite and
91 objectClass/attributeType mapping.
95 This overlay implements the provider-side support for
97 replication, including persistent search functionality.
101 This overlay can be used with a backend database such as
103 to create a "translucent proxy".
104 Content of entries retrieved from a remote LDAP server can be partially
105 overridden by the database.
108 Attribute Uniqueness.
109 This overlay can be used with a backend database such as
111 to enforce the uniqueness of some or all attributes within a subtree.
115 This overlay can be used to enforce a specific order for the values
116 of an attribute when it is returned in a search.
