[horde] Extending userid's in Horde by a realm

Thanks Michael,

I tried this but after log in I get a blank page (in

public function authusername($userId, $toHorde){
   if ($toHorde) {
    $imap = $GLOBALS['injector']->getInstance('IMP_Factory_Imap');
      $hostspec = $imap->ob->getParam('hostspec');
      $servers = IMP_Imap::loadServerConfig();
      foreach ($servers as $server) {
         if ($server['hostspec'] == $hostspec) {
            $userId = $userId . '@' . $server['realm'];
      return $userId;
      $userId = substr($userId, 0, strpos($userId, '@'));
      return $userId;

This first problem is "$imap =
$GLOBALS['injector']->getInstance('IMP_Factory_Imap');" This execution seems
not to work in Horde 5.1.6. 
In imps' backend.local.php I've  added    " 'realm' =>
'mailserver.domain.com', " to every server in the server array.

How can I modify the userid?

Horde's 'authusername' hook.
