NAME         top

       slapd.plugin - plugin configuration for slapd, the stand-alone
       LDAP daemon

SYNOPSIS         top


DESCRIPTION         top

       The slapd.conf(5) file contains configuration information for the
       slapd(8) daemon. This configuration file is also used by the
       SLAPD tools slapadd(8), slapcat(8), slapmodify(8), and

       The slapd.conf file consists of a series of global configuration
       options that apply to slapd as a whole (including all backends),
       followed by zero or more database backend definitions that
       contain information specific to a backend instance.

       The general format of slapd.conf is as follows:

           # comment - these options apply to every database
           <global configuration options>
           # first database definition & configuration options
           database    <backend 1 type>
           <configuration options specific to backend 1>
           # subsequent database definitions & configuration options

       If slapd is compiled with --enable-slapi, support for plugins
       according to Netscape's Directory Server Plug-Ins.  Version 4 of
       the API is currently implemented, with some extensions from
       version 5.

       Both global and database specific data may contain plugin
       information.  Plugins associated with a specific database are
       called before global plugins.  This manpage details the slapd(8)
       configuration statements that affect the loading of SLAPI

       Arguments that should be replaced by actual text are shown in
       brackets <>.

       The structure of the plugin directives is

       plugin <type> <lib_path> <init_function> [<arguments>]
              Load a plugin of the specified type for the current

       The <type> can be one of preoperation, that is executed before
       processing the operation for the specified database,
       postoperation, that is executed after the operation for the
       specified database has been processed, extendedop, that is used
       when executing an extended operation, or object.  The latter is
       used for miscellaneous types such as ACL, computed attribute and
       search filter rewriter plugins.

       The <libpath> argument specifies the path to the plugin loadable
       object; if a relative path is given, the object is looked for
       according to the underlying dynamic loading package (libtool's
       ltdl is used).

       The <init_function> argument specifies what symbol must be called
       when the plugin is first loaded.  This function should register
       the functions provided by the plugin for the desired operations.
       It should be noted that it is this init function, not the plugin
       type specified as the first argument, that determines when and
       for what operations the plugin will be invoked.  The optional
       <arguments> list is passed to the init function.

       pluginlog <file>
              Specify an alternative path for the plugin log file
              (default is LOCALSTATEDIR/errors).

       modulepath <pathspec>
              This statement sets the module load path for dynamically
              loadable backends, as described in slapd.conf(5); however,
              since both the dynamically loadable backends and the SLAPI
              plugins use the same underlying library (libtool's ltdl)
              its value also affects the plugin search path.  In general
              the search path is made of colon-separated paths; usually
              the user-defined path is searched first; then the value of
              the LTDL_LIBRARY_PATH environment variable, if defined, is
              used; finally, the system-specific dynamic load path is
              attempted (e.g. on Linux the value of the environment
              variable LD_LIBRARY_PATH).  Please carefully read the
              documentation of ltdl because its behavior is very
              platform dependent.
