OK, I got it working but I had to comment out part of the code in index.php:
/*-------------------------------------* // try to log in if ($_action=='login' && $_task=='mail') { $host = $_POST['_host'] ? $_POST['_host'] : $CONFIG['default_host'];
// check if client supports cookies if (empty($_COOKIE)) { show_message("cookiesdisabled", 'warning'); } else if (isset($kuser) && isset($kpass) && rcmail_login($kuser, $kpass, $host)) { // send redirect header("Location: $COMM_PATH"); exit; } else { show_message("loginfailed", 'warning'); $_SESSION['user_id'] = ''; } }
// end session else if ($_action=='logout' && isset($_SESSION['user_id'])) { show_message('loggedout'); rcmail_kill_session(); }
// check session cookie and auth string else if ($_action!='login' && $sess_auth && $_SESSION['user_id']) { if ($_auth !== $sess_auth || $_auth != rcmail_auth_hash($_SESSION['client_id'], $_SESSION['auth_time']) || ($CONFIG['session_lifetime'] && isset($SESS_CHANGED) && $SESS_CHANGED
- $CONFIG['session_lifetime']*60 < mktime())) { $message = show_message('sessionerror', 'error'); rcmail_kill_session(); } }
/*-------------------------------------*/
