6 slapd.backends \- backends for slapd, the stand-alone LDAP daemon
10 daemon can use a variety of different backends for serving LDAP requests.
11 Backends may be compiled statically into slapd, or when module support
12 is enabled, they may be dynamically loaded. Multiple instances of a
13 backend can be configured, to serve separate databases from the same
17 Configuration options for each backend are documented separately in the
19 .BR slapd-<backend> (5)
23 This is the recommended primary backend for a normal slapd database.
24 It takes care to configure it properly.
25 It uses the transactional database interface of the Oracle Berkeley
26 DB (BDB) package to store data.
29 This backend is used to manage the configuration of slapd at run-time.
30 Unlike other backends, only a single instance of the
32 backend may be defined. It also instantiates itself automatically,
33 so it is always present even if not explicitly defined in the
38 This backend is experimental.
39 It serves up referrals based upon SRV resource records held in the
43 This is a variant of the
45 backend that uses a hierarchical database
46 layout. This layout stores entry DNs more efficiently than the
49 using less space and requiring less work to create, delete, and rename
50 entries. It is also one of the few backends to support subtree renames.
53 This backend acts as a proxy to forward incoming requests to another
57 This database uses the filesystem to build the tree structure
58 of the database, using plain ascii files to store data.
59 Its usage should be limited to very simple databases, where performance
60 is not a requirement. This backend also supports subtree renames.
63 This backend performs basic LDAP proxying with respect to a set of
64 remote LDAP servers. It is an enhancement of the
69 This backend provides information about the running status of the slapd
70 daemon. Only a single instance of the
72 backend may be defined.
75 Operations in this backend succeed but do nothing.
78 This backend is provided for demonstration purposes only.
79 It serves up user account information from the system
86 interpreter into slapd.
87 It runs Perl subroutines to implement LDAP operations.
90 This backend is experimental.
91 It redirects LDAP operations to another database
92 in the same server, based on the naming context of the request.
97 for details) to rewrite the naming context of the request.
98 It is primarily intended to implement virtual views on databases
99 that actually store data.
102 This backend executes external programs to implement LDAP operations.
103 It is primarily intended to be used in prototypes.
106 This backend is experimental.
107 It services LDAP requests from an SQL database.
