Аутентификация Symfony 2 с (доктриной) Entity

Кажется, я перепробовал весь код во всех сообщениях об аутентификации с помощью (доктрина) Сущность в Symfony 2. И я не могу заставить ее работать. Когда я использую поставщика in_memory, все работает нормально. Я использую PR8.

My security.yml

security:
    encoders:
        Partners\FrontendBundle\Entity\User:       plaintext
        Symfony\Component\Security\Core\User\User: plaintext
    providers:
        main:
            entity: { class: FrontendBundle:User, property: username }
        #        in_memory:
        #            users:
        #                sergi:        { password: boo123, roles: [ 'ROLE_USER' ] }
    firewalls:
        main:
            pattern:         /.*
            form_login:      true
            anonymous:       true
            logout:          true
    access_control:
        - { path: /docs.*, role: ROLE_USER }
        - { path: /control.*, role: ROLE_USER }
        - { path: /.*, role: IS_AUTHENTICATED_ANONYMOUSLY }
    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER

My User entity

The UserRepository

findOneBy(array('username' => $username));
        }
        function loadUser(UserInterface $user)
        {
            return $user;
        }
        function loadUserByAccount(AccountInterface $account)
        {
            return $this->loadUserByUsername($account->getUsername());
        }
        public function supportsClass($class)
        {
            return true;
        }
    }

Когда я заполняю форму входа в систему, появляется ошибка в $ error = $ this-> get ( 'запрос') -> getSession () -> get (SecurityContext :: AUTHENTICATION_ERROR); это:

Я не знаю, в чем может быть проблема.
