[fw-general] using of two auth in zend

[shahrzad khorrami]

hi all,

I have two module: account, admin

I want each of them have their authentication to login...
for their auth, I created two controller in each module(AuthController.php)
now we have just hasIdentify to auth.. but how I say it that it is account
and other is admin...
now when I login each index module login.......

Admin_IndexController
    public function init()
    {
        /* Initialize action controller here */
                $auth = Zend_Auth::getInstance();
                if (!$auth->hasIdentity()) {
                         Zend_Auth::getInstance()->clearIdentity();
                            $this->_redirect('/admin/auth/login');
                }
                else{
                   $this->_forward('index');
                }
    }


 How we can implement account login and admin panel login in zend (two
different authentiation in zend????????)
