注册后Symfony3自动登录

Question

当我手动完成日志登录并重定向时，我的错误是什么，但是我再次登录了 这是我的安全

security:
    encoders:
        AppBundle\Entity\User:

            iterations: 1

    oauth_authorize:
        pattern:    ^/oauth/v2/auth
        form_login:
            provider: user_provider

        fos_oauth:  true
        stateless:  true
        anonymous:  false

    secured_area: %secured_area%

注册控制器如下：

public function registrationAction($invitation, Request $request) {
    $providerKey = 'secured_area'; 

    $token = new UsernamePasswordToken($user, null, $providerKey, $user->getRoles());
    $this->get('security.token_storage')->setToken($token);
    $this->get('session')->set('_security_secured_area', serialize($token));

    $logueado = $this->container->get('security.token_storage')->getToken()->getUser();
    // If I print the log in, the user who has just registered will
    // return it and I am trying to login but still do not log me in

    $url = $this->generateUrl('dashboard');

    return $this->redirect($url);

}
