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.
40 Collective Attributes.
41 This overlay implements RFC 3671 collective attributes; these
42 attributes share common values over all the members of the collection
43 as inherited from an ancestor entry.
47 This overlay enforces a regular expression constraint on all values
48 of specified attributes. It is used to enforce a more rigorous
49 syntax when the underlying attribute syntax is too general.
52 Dynamic Directory Services.
53 This overlay supports dynamic objects, which have a limited life after
54 which they expire and are automatically deleted.
58 This is a demo overlay which extends the Compare operation to detect
59 members of a dynamic group.
60 It has no effect on any other operations.
64 This overlay allows expansion of dynamic groups and more.
68 This overlay maintains automatic reverse group membership values,
69 typically stored in an attribute called memberOf.
73 This overlay forwards simple bind requests on a local database to a
78 This overlay allows caching of LDAP search requests in a local database.
79 It is most often used with the
87 This overlay provides a variety of password control mechanisms,
88 e.g. password aging, password reuse and duplication control, mandatory
92 Referential Integrity.
93 This overlay can be used with a backend database such as
95 to maintain the cohesiveness of a schema which utilizes reference
100 This overlay is useful to test the behavior of clients when
101 server-generated erroneous and/or unusual responses occur.
105 This overlay is experimental.
106 It performs basic DN/data rewrite and
107 objectClass/attributeType mapping.
110 Server Side Sorting and Virtual List Views.
111 This overlay implements the RFC2891 server-side sorting control and
112 virtual list view controls, and replaces the RFC2696 paged-results
113 implementation to ensure it works with the sorting technique.
117 This overlay implements the provider-side support for
119 replication, including persistent search functionality.
123 This overlay can be used with a backend database such as
125 to create a "translucent proxy".
126 Content of entries retrieved from a remote LDAP server can be partially
127 overridden by the database.
130 Attribute Uniqueness.
131 This overlay can be used with a backend database such as
133 to enforce the uniqueness of some or all attributes within a subtree.
137 This overlay can be used to enforce a specific order for the values
138 of an attribute when it is returned in a search.
