# Configuration for dokuwiki LDAP configuration is in ```/dokuwiki/conf/local.protected.php```: ``` DokuWiki > Authentication. On the Authentication backend, select ```authldap``` and save the changes. ## Internal (or other authentication) fallback If you dont want to use LDAP authentication exclusively, you can install the [authchained plugin](https://www.dokuwiki.org/plugin:authchained). It tries multiple auth backends when a user logs in. ``` $conf['authtype'] = 'authchained'; $conf['plugin']['authchained']['authtypes'] = 'authldap:authplain'; ```
