Я пытаюсь аутентифицировать пользователя:

<?php 

/**
 * @Route("/testLogin", name="testLogin")
 */
public function testLoginAction()
{
    $em = $this->getDoctrine()->getEntityManager();
    $user = $em->getRepository('ApplicationDefaultBundle:User')->findOneBy(array('id' => 126));

    $providerKey = 'main';
    $token = new UsernamePasswordToken($user, null, $providerKey, $user->getRoles());

    $this->container->get('security.context')->setToken($token);

    return $this->redirect($this->generateUrl('testCheck'));
}

/**
 * @Route("/testCheck", name="testCheck")
 */
public function testCheckAction()
{
    if (false === $this->get('security.context')->isGranted(
        'IS_AUTHENTICATED_REMEMBERED'
    )) {
        return new Response('Not logged');
    }
    $user = $this->container->get('security.context')->getToken()->getUser();

    return new Response($user->getUsername.' is logged');
}

Но я получаю постоянное перенаправление 302 на страницу / логин.

    access_control:

Код для аутентификации я беру уhttps://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Controller/RegistrationController.php

Ошибка в приложении / logs / dev.log:

redirecting to authentication entry point (No Authentication Provider found for token of class "Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken".) [] []

Я не могу получить доступ к сайту, пока не уберу куки.
