Need Help
5

I did that and no result…

My problem comes exactly after the login, when i get to another controller, i can not get the autentified user from here…

In controller after the login…

public function beforeFilter(Event $event)
{
parent::beforeFilter($event);

$user = $this->Auth->user();

if( $this->isAuthorized(  $user  )  )
{
    $this->Auth->allow();            
    $this->set('auth_user', $user );            
    return;
}

}

$user is null…

Any idea ?

Thank you…
