如何同时在2个不同的symfony2防火墙上进行身份验证？

security:
    providers:
        main:
            entity:
                class: AppBundle:User
                property: username

security:
    firewalls:
        main:
            pattern: ^/
            form_login:
                login_path: login
                check_path: login_check
                default_target_path: home
                provider: main
                csrf_token_generator: security.csrf.token_manager

security:
    firewalls:
        main:
            pattern: ^/
            form_login:
                # ...
