No - this is only used if 'preferred' is set in backends.php.  Don't  
set preferred.

public function preauthenticate($userId, $credentials)
{
     // Do magic here to determine the preferred server.  Store the  
preferred server key (from backends.php)
     // in $key

     $credentials['server'] = $key;

     return $credentials;
}
