身份验证访问控制ROLES

使用symfony2.1和FOSFacebookBundle：

如果用户正在键入www.example.com，例如用户关闭了他的浏览器，如果他仍然经过身份验证，我想重定向到www.example.com/secured .

如果用户通过身份验证，我无法访问indexAction .

我的Security.yml：

security:
encoders:
    Symfony\Component\Security\Core\User\User: plaintext

role_hierarchy:
    ROLE_ADMIN:       ROLE_USER
    ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]

providers:
    in_memory:
        memory:
            users:
                user:  { password: userpass, roles: [ 'ROLE_USER' ] }
                admin: { password: adminpass, roles: [ 'ROLE_ADMIN' ] }
    my_fos_facebook_provider:
            id: my.facebook.user
                 //How can I add here a ROLE_USER?

firewalls:

     //standard thing from FosFacebookBundle

access_control:
    - { path: ^/, roles: [IS_AUTHENTICATED_ANONYMOUSLY]  }

我的indexAction：

if( $this->container->get('security.context')
    ->isGranted('IS_AUTHENTICATED_FULLY') ){
   echo 'asdf'; //this is working in the secured area www.example.com/secured/
}

My error message: 安全上下文不包含身份验证令牌 . 一个可能的原因可能是没有为此URL配置防火墙 .

在安全区域，用户没有任何角色 . 我该怎么改变它？

怎么了？

UPDATE
