php - CakePHP 2.4.5 Auth - isAuthorized not being called -

this may repeated question have gone through other answers , none of them worked me :(

the following code in appcontroller:

public $components = array(     'auth',     'session' );  public function beforefilter() {     $this->auth->authorize = 'controller';     $this->auth->authenticate = array(         'form' => array(             'fields' => array('username' => 'email', 'password' => 'password'),             'scope' => array('user.active' => 1),             'passwordhasher' => 'blowfish'         )     ); }  public function isauthorized($user) {     debug($this->request->params);     exit; } 

i not overriding beforefilter or isauthorized function in of other controllers. no matter page open not calling isauthorized function , taking me login page. please help!

authorization checks made after successful authentication, see authcomponent::startup().

public function startup(controller $controller) {     // ...      // authenticate first      if (!$this->_getuser()) {         return $this->_unauthenticated($controller);     }      // authorize     if ($this->_isloginaction($controller) ||         empty($this->authorize) ||         $this->isauthorized($this->user())     ) {         return true;     }      // ... } 

so solution should log in first.
