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 compiled 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. constraint Constraint. This overlay enforces a regular expression constraint 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 auto- matically 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. 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 duplica- tion 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. syncprov Syncrepl Provider. This overlay implements the provider-side support for syncrepl replication, including persistent search func- tionality. 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. FILES
