System administrators may want to have their survey administrators authenticated against a central authentication system (Active Directory, openLdap, Radius, ...) rather than using the internal LimeSurvey database. An easy way to do this is to setup your web server software to use this external authentication system, and then ask LimeSurvey to trust the user identity reported by the web server. In order to enable this feature, you have to:
 * set auth_webserver to 'true' in config.php;
 * enable authentication from the web server side.
