Система аутентификации в symfony2 не работает?

У меня проблема с моей системой аутентификации в symfony2.

Мой файл маршрутизации:

shop_show_login_page:
path: /login
defaults: { _controller: ShopDesktopBundle:User:loginPage }
shop_login_user:
path: /loginUser
defaults: { _controller: ShopDesktopBundle:User:loginCheck }
shop_logout_user:
path: /logout

Мой пользовательский контроллер:

class UserController extends Controller{
public function loginPageAction(){
return $this->render('ShopDesktopBundle:User:loginPage.html.twig');
}
public function loginCheckAction(Request $request){
$password = $request->request->get('password');
$login    = $request->request->get('username');
$em = $this->getDoctrine()->getEntityManager();
$repository = $em->getRepository('ShopDesktopBundle:Customer');
$user = $repository->findOneBy(array('customer_login'=> $login, 'customer_password'=> $password));
if($user){
return $this->redirect($this->generateUrl('shop_desktop_homepage'));
}else{
return $this->render('ShopDesktopBundle:User:loginPage.html.twig',array('message_failed' => 'Eroare : wrong login'));
}
}
}

Мой взгляд :

{% if message_failed is defined %}
<div class="alert alert-danger">
<button type="button" class="close" data-dismiss="alert">×</button>
<strong>{{ message_failed }}</strong>
</div>
{% endif %}
<form action="{{ path('shop_login_user') }}" method="post">
<div class="form-group">
<div class="input-group">
<span class="input-group-addon"><i class="fa fa-user"></i></span>
<input type="text" class="form-control" placeholder="Username" name="username">
</div>
</div>
<div class="form-group">
<div class="input-group">
<span class="input-group-addon"><i class="fa fa-lock"></i></span>
<input type="text" class="form-control" placeholder="Password" name="password">
</div>
</div>
<div class="form-group">
<button type="submit" class="button">Authentification</button>
</div>
</form>

Панель инструментов отладки показывает, что я аутентифицировался как аноним после отправки формы входа в систему для всех ситуаций, и я не понимаю, в чем проблема. Есть решение? Может кто-нибудь мне помочь?. Спасибо заранее
