Hi, i am developing small authentication module on 4.7 + patch allowing authenticating without @domain My module is very simple (code here is little bit condensed): function auth602_help($section = '') { ... } function auth602_info($field = 0) { $info['name'] = '602Office'; $info['protocol'] = 'XML-RPC'; if ($field) { return $info[$field]; } else { return $info; } } function auth602_auth($username, $password, $server) { // authenticate if ($authenticated) { return 1; } else { return 0; } // end of module Everything works, my "Default authentication server" is "xyz.cz", so when user write "someuser", hook_auth() processes someuser@xyz.cz But, after authenticating, user is logged in and Drupal throws error: "Error -404 : not found" I am trying to debug where this message come from (for 3 hours now :(. Is there any way to look up module or function which throwed this error or do anybody know why this error appears? Nothing else is wrong. Just this message. User still authenticated. Thanks, Jakub Suchy http://www.drupal.cz
