NAME
     slapd-wt - WiredTiger backend to slapd

SYNOPSIS
     /usr/local/etc/openldap/slapd.conf

DESCRIPTION
     The wt backend to slapd(8) uses WiredTiger database library to store data.

     The  wt  backend is experimental module that have potential high write per-
     formance and high concurrency performance.  This backend have not some  ba-
     sic feature yet. Please backup data using slapcat before update the module.

CONFIGURATION
     These  slapd.conf	options apply to the wt backend database.  That is, they
     must follow a "database wt" line and come before any  subsequent  "backend"
     or   "database"  lines.   Other  database	options  are  described  in  the
     slapd.conf(5) manual page.

     directory <directory>
	    Specify WiredTiger home directory that containing this database  and
	    associated indexes live.  A separate directory must be specified for
	    each database.  The default is /var/db/openldap-data.

     idlcache <boolean>
	    Use the in-memory idlcache. The default is true.

     index {<attrlist>|default} [pres,eq,approx,sub,<special>]
	    Specify  the indexes to maintain for the given attribute (or list of
	    attributes).  Some attributes only support a subset of indexes.   If
	    only an <attr> is given, the indices specified for default are main-
	    tained.  Note that setting a default does not imply that all attrib-
	    utes will be indexed. Also, for best performance, an eq index should
	    always be configured for the objectClass attribute.

     mode <integer>
	    back-wt does not support mode option. use umask instead.

     wtconfig {create,cache_size=512M,async=(enabled)}
	    Specify  configuration  for  wiredtiger,  This  parameter is pass to
	    wiredtiger_open(3).

	    create
		   create the database if it does not exist.

	    cache_size
		   maximum heap memory to allocate for the cache.

	    async  asynchronous operations configuration  options.  disabled  by
		   default.

ACCESS CONTROL
     The  wt  backend  honors access control semantics as indicated in slapd.ac-
     cess(5).
