Description

SLAPD.OVERLAYS(5oldap)                                  SLAPD.OVERLAYS(5oldap)



NAME
       slapd.overlays - overlays for slapd, the stand-alone LDAP daemon

DESCRIPTION
       The slapd(8) daemon can use a variety of different overlays to alter or
       extend the normal behavior of a database backend.  Overlays may be com-
       piled  statically  into  slapd, or when module support is enabled, they
       may be dynamically loaded. Most of the overlays are only allowed to  be
       configured  on  individual  databases,  but some may also be configured
       globally.

       Configuration options for each overlay are documented separately in the
       corresponding slapo-<overlay>(5) manual pages.

       accesslog
              Access  Logging.   This  overlay  can record accesses to a given
              backend database on another database.

       auditlog
              Audit Logging.  This overlay records changes on a given  backend
              database to an LDIF log file.  By default it is not built.

       chain  Chaining.  This overlay allows automatic referral chasing when a
              referral would have been returned, either when configured by the
              server or when requested by the client.

       collect
              Collective Attributes.  This overlay implements RFC 3671 collec-
              tive attributes; these attributes share common values  over  all
              the  members  of  the  collection  as inherited from an ancestor
              entry.

       constraint
              Constraint.  This overlay enforces  a  regular  expression  con-
              straint  on  all  values  of specified attributes. It is used to
              enforce a more rigorous syntax  when  the  underlying  attribute
              syntax is too general.

       dds    Dynamic  Directory  Services.   This  overlay  supports  dynamic
              objects, which have a limited life after which they  expire  and
              are automatically deleted.

       dyngroup
              Dynamic Group.  This is a demo overlay which extends the Compare
              operation to detect members of  a  dynamic  group.   It  has  no
              effect on any other operations.

       dynlist
              Dynamic  List.   This overlay allows expansion of dynamic groups
              and more.

       memberof
              MemberOf.  This overlay maintains automatic reverse  group  mem-
              bership  values,  typically  stored  in an attribute called mem-
              berOf.

       pbind  Proxybind.  This overlay forwards  simple  bind  requests  on  a
              local database to a remote LDAP server.

       pcache Proxycache.  This overlay allows caching of LDAP search requests
              in  a  local  database.   It  is  most  often  used   with   the
              slapd-ldap(5) or slapd-meta(5) backends.

       ppolicy
              Password  Policy.   This  overlay provides a variety of password
              control mechanisms, e.g.  password  aging,  password  reuse  and
              duplication control, mandatory password resets, etc.

       refint Referential  Integrity.  This overlay can be used with a backend
              database such as slapd-bdb(5) to maintain the cohesiveness of  a
              schema which utilizes reference attributes.

       retcode
              Return  Code.   This  overlay  is useful to test the behavior of
              clients when server-generated erroneous and/or unusual responses
              occur.

       rwm    Rewrite/remap.  This overlay is experimental.  It performs basic
              DN/data rewrite and objectClass/attributeType mapping.

       sssvlv Server Side Sorting and Virtual List Views.  This overlay imple-
              ments  the  RFC2891 server-side sorting control and virtual list
              view controls, and replaces the RFC2696 paged-results  implemen-
              tation to ensure it works with the sorting technique.

       syncprov
              Syncrepl  Provider.   This  overlay implements the provider-side
              support for syncrepl replication,  including  persistent  search
              functionality.

       translucent
              Translucent  Proxy.   This  overlay  can  be used with a backend
              database such as slapd-bdb(5) to create a  "translucent  proxy".
              Content  of  entries  retrieved from a remote LDAP server can be
              partially overridden by the database.

       unique Attribute Uniqueness.  This overlay can be used with  a  backend
              database  such as slapd-bdb(5) to enforce the uniqueness of some
              or all attributes within a subtree.

       valsort
              Value Sorting.  This overlay can be used to enforce  a  specific
              order  for  the  values of an attribute when it is returned in a
              search.
