如何將 Question2Answer 集成到 Typo3 中？

Question2Answer提供了實現Single Sign On的選項。我想將它集成到 Typo3 的現有安裝中（對於 Typo3 前端使用者）。我的問題：

• SSO 需要特定的 Typo3 外掛嗎？
• 對於 Typo3 ，Q2A 的qa-external-users.php的實現如何？

第一次嘗試：qa-external-users.phpqa_*的函式現在只需呼叫以下腳本中的相應函式。t3_*

錯字3.php：

<?php

function connect() {

   static $t3_db_connection = null;

   if (!$t3_db_connection) {

       $conf = include '/YOUR/PATH/TO/TYPO3/typo3conf/LocalConfiguration.php';

       $t3_db_connection = mysql_connect(
           $conf['DB']['host'],
           $conf['DB']['username'],
           $conf['DB']['password']
       );

       if(!$t3_db_connection) {
           die('Could not connect: ' . mysql_error());
       }

       mysql_select_db($conf['DB']['database']);
   }
   return $t3_db_connection;
}

function logged_in_userid() {
       $con = connect();
       $cookie = $_COOKIE["fe_typo_user"];
       $result = mysql_fetch_assoc(mysql_query("SELECT ses_userid FROM fe_sessions WHERE ses_id = '$cookie'", $con));
   return $result['ses_userid'];
}

function t3_get_logged_in_user() {

   $con = connect();
   $userid = logged_in_userid();
   $result = mysql_fetch_assoc(mysql_query("SELECT * FROM fe_users WHERE uid = '$userid' AND deleted = 0", $con));
   $username = $result['username'];
   $usergroup = $result['usergroup'];
   $blocked = $result['disable'];
   $publicusername = $result['name'];
   $email = $result['email'];
   $groups = explode(',', $usergroup);

   return !$userid ? null : array(
       'userid' => $userid,
       'publicusername' => $publicusername,
       'email' => $email,
       //'passsalt' => ?????,
       'level' => in_array(6, $groups) ? QA_USER_LEVEL_SUPER : QA_USER_LEVEL_BASIC, // TODO add other group ids
       'blocked' => $blocked
   );
}

function t3_get_user_email($userid) {
   $con = connect();
       $result = mysql_fetch_assoc(mysql_query("SELECT email FROM fe_users WHERE uid = '$userid' AND deleted = 0", $con));
       $email = $result['email'];

   return !$email ? null : $email;
}

function t3_get_userids_from_public($publicusernames) {

   $publictouserid = array();

   if (count($publicusernames)) {
       $con = connect();
       $escapedusernames = array();
       foreach ($publicusernames as $publicusername)
           $escapedusernames[] = "'".mysql_real_escape_string($publicusername, $con)."'";

       $results = mysql_query(
           'SELECT name, uid FROM fe_users WHERE name IN ('.implode(',', $escapedusernames).')', $con);

       while ($result = mysql_fetch_assoc($results))
           $publictouserid[$result['name']] = $result['uid'];
   }

   return $publictouserid;
}

function t3_get_public_from_userids($userids) {

       $useridtopublic = array();

       if (count($userids)) {
               $con = connect();
               $escapeduserids = array();
               foreach ($userids as $userid)
                       $escapeduserids[] = "'".mysql_real_escape_string($userid, $con)."'";

               $results = mysql_query(
                       'SELECT name, uid FROM fe_users WHERE uid IN ('.implode(',', $escapeduserids).')', $con);

               while ($result = mysql_fetch_assoc($results))
                       $useridtopublic[$result['uid']] = $result['name'];
       }

       return $useridtopublic;
}
