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?
