Symfony2 Logged in but NOT Authenticated

Question

security.yml

security:

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

    encoders: 
        Karl\UserBundle\Entity\User: plaintext

    providers:
        main:
            entity:
                class: Karl\UserBundle\Entity\User
                property: email

    firewalls:

        secured_area:
            pattern: ^/
            anonymous: ~
            provider: main
            form_login:
                check_path: login_check
                login_path: login
                username_parameter: _email
            logout:
                path: logout
                target: /

        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false

If i put an access control for a certain page, the problem will go away but previously it did not need the acl and it will work fine, anyone know whats the problem or did i do something wrong with the firewall?

The user is logged in with ROLE_USER and the username is also detected but not authenticated.

Answer 1

Ok i found out what is the problem,

For the User Entity, i took out \\Serializable and it's working now. One question, how does taking it out make the user authenticated?

/**
 * User
 *
 * @ORM\Table(name="User")
 * @ORM\Entity
 * @UniqueEntity("email")
 */
class User implements UserInterface, \Serializable <--taken out and problem solved but why?
