NAME
       slapd-wt - WiredTiger backend to slapd

SYNOPSIS
       /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
       performance and high concurrency performance.  This backend have not
       some basic 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/lib/openldap/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 maintained.  Note that setting a default does not
              imply that all attributes 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.access(5).
