Login takes away the slug from my URL - cakephp

Question

I'm working Cake 2.1.3, and the routes.php file, everything worked fine except the login management, for example I want my url be as follows:
http://mysite.com/companyx/users/login
where companyx is the slug, however when you run that url in the browser is as follows:
http://mysite.com/users/login
In this file routes.php I have defined as follows:
Router::connect(
'/:slug/users/login', // E.g. /companyx/users/login
array('controller' => 'users', 'action' => 'login'), array(
// order matters
'pass' => array('slug')
)
);
With other controllers I have no problems such as:
Router::connect(
'/:slug/users', // E.g. /companyx/users
array('controller' => 'users', 'action' => 'index'), array(
// order matters
'pass' => array('slug')
)
);
Best Regards ;)

Answer 1

CakePHP has a default login action defined in the AuthComponent. (line 171)
/**
* A URL (defined as a string or array) to the controller action that handles
* logins. Defaults to `/users/login`
*
* #var mixed
*/
public $loginAction = array(
'controller' => 'users',
'action' => 'login',
'plugin' => null
);
You can override this action with the beforeFilter in your own UsersController.

Answer 2

thanks for you answer. I solved this case this way:
public function beforeFilter() {
parent::beforeFilter();
if (!$this->request->is('post')) {
$this->Auth->loginAction = 'this is:slug/users/login/';
}
}
Where "this is slug", should be the slug.
Best Regards.
