See COPYRIGHT/LICENSE. +.\" $OpenLDAP$ +.SH NAME +slapd.backends \- backends for slapd, the stand-alone LDAP daemon +.SH DESCRIPTION +The +.BR slapd (8) +daemon can use a variety of different backends for serving LDAP requests. +Backends may be compiled statically into slapd, or when module support +is enabled, they may be dynamically loaded. Multiple instances of a +backend can be configured, to serve separate databases from the same +slapd server. + + +Configuration options for each backend are documented separately in the +corresponding +.BR slapd\-<backend> (5) +manual pages. +.TP +.B asyncmeta +This backend performs basic LDAP proxying with respect to a set of +remote LDAP servers. It is an enhancement of the +.B ldap +backend that operates asynchronously, to prevent tying up slapd threads +while waiting for operations to complete. +.TP +.B config +This backend is used to manage the configuration of slapd at run-time. +Unlike other backends, only a single instance of the +.B config +backend may be defined. It also instantiates itself automatically, +so it is always present even if not explicitly defined in the +.BR slapd.conf (5) +file. +.TP +.B dnssrv +This backend is experimental. +It serves up referrals based upon SRV resource records held in the +Domain Name System. +.TP +.B ldap +This backend acts as a proxy to forward incoming requests to another +LDAP server. +.TP +.B ldif +This database uses the filesystem to build the tree structure +of the database, using plain ascii files to store data. +Its usage should be limited to very simple databases, where performance +is not a requirement. This backend also supports subtree renames. +.TP +.B mdb +This is the recommended primary backend. +This backend uses OpenLDAP's own MDB transactional database +library. This backend also supports subtree renames. +.TP +.B meta +This backend performs basic LDAP proxying with respect to a set of +remote LDAP servers. It is an enhancement of the +.B ldap +backend. +.TP +.B monitor +This backend provides information about the running status of the slapd +daemon. Only a single instance of the +.B monitor +backend may be defined. +.TP +.B ndb +This backend is experimental, incomplete, and deprecated. +It uses the transactional database interface of the MySQL Cluster Engine +(NDB) to store data. Note that Oracle, which now owns MySQL, has withdrawn +support for NDB and this backend is unlikely to be developed any further. +.TP +.B null +Operations in this backend succeed but do nothing. +.TP +.B passwd +This backend is provided for demonstration purposes only. +It serves up user account information from the system +.BR passwd (5) +file. +.TP +.B perl +This backend embeds a +.BR perl (1) +interpreter into slapd. +It runs Perl subroutines to implement LDAP operations. +This backend is deprecated. +.TP +.B relay +This backend is experimental. +It redirects LDAP operations to another database +in the same server, based on the naming context of the request. +Its use requires the +.B rwm +overlay (see +.BR slapo\-rwm (5) +for details) to rewrite the naming context of the request. +It is primarily intended to implement virtual views on databases +that actually store data. +.TP +.B sql +This backend is experimental and deprecated. +It services LDAP requests from an SQL database. +.TP +.B wiredtiger +This backend is experimental. +It services LDAP requests from a wiredtiger database. +.SH FILES +.TP +ETCDIR/slapd.conf +default slapd configuration file +.TP +ETCDIR/slapd.d +default slapd configuration directory +.SH SEE ALSO +.BR ldap (3), +.BR slapd\-asyncmeta (5), +.BR slapd\-config (5), +.BR slapd\-dnssrv (5), +.BR slapd\-ldap (5), +.BR slapd\-ldif (5), +.BR slapd\-mdb (5), +.BR slapd\-meta (5), +.BR slapd\-monitor (5), +.BR slapd\-ndb (5), +.BR slapd\-null (5), +.BR slapd\-passwd (5), +.BR slapd\-perl (5), +.BR slapd\-relay (5), +.BR slapd\-sql (5), +.BR slapd\-wt (5), +.BR slapd.conf (5), +.BR slapd.overlays (5), +.BR slapd (8). +"OpenLDAP Administrator's Guide" (http://www.OpenLDAP.org/doc/admin/) +.SH ACKNOWLEDGEMENTS +.so ../Project |
