Hi,if you're not using a username and a password to connect to the ldap server (anonymous bind) auth-ldap will fail to work.You will need to modify the authenticate.php on line 174.Remove the "return false" and add instead: else { // try anonymous bind $r = $connection->bind(); return !PEAR:($r); }It would be great if some could commit this and do a push.ThanksMatthias
