FOS UserBundle Access Denied - symfony

Question

I'm trying to use FOS UserBundle to manage users on my project.
Here is my security.yml file :
security:
encoders:
Symfony\Component\Security\Core\User\User: plaintext
FOS\UserBundle\Model\UserInterface: sha512
role_hierarchy:
ROLE_ADMIN: ROLE_USER
ROLE_SUPER_ADMIN: ROLE_ADMIN
providers:
in_memory:
memory:
users:
user: { password: userpass, roles: [ 'ROLE_USER' ] }
admin: { password: adminpass, roles: [ 'ROLE_ADMIN' ] }
fos_userbundle:
id: fos_user.user_provider.username
firewalls:
main:
pattern: ^/
form_login:
provider: fos_userbundle
csrf_provider: form.csrf_provider
logout: true
anonymous: true
access_control:
#- { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY, requires_channel: https }
- { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/, role: ROLE_ADMIN }
I have manually set my user's rights in my controller like below :
public function testGroupsAction( UserInterface $user )
{
$user->addRole("ROLE_ADMIN");
$this->getDoctrine()->getManager()->persist($user);
$this->getDoctrine()->getManager()->flush();
echo "<pre>";
\Doctrine\Common\Util\Debug::dump($user->getRoles());
echo "</pre>";die;
}
the $user->getRoles() function returns me an array with all my user's roles :
array (size=3)
0 => string 'ROLE_SUPER_ADMIN' (length=16)
1 => string 'ROLE_ADMIN' (length=10)
2 => string 'ROLE_USER' (length=9)
(ROLE_SUPER_ADMIN has been added during my tests)
However when i try to reach a route like "/admin/my/route"n i've got a 403 access forbidden.
Any idea why Symfony doesn't want my user to access admin pages?
Edit :
When i look in the profiler, the user only has [ROLE_USER]...
Thank you.

I finally got it working.
Thanks to Zizoujab, I tried FOSUserBundle's commands to promote a user :
> php app/console fos:user:promote myUser
It worked perfectly well. However, as I have no ssh access nor any other command line tool on my server, i needed to do it via PHP code.
So i went to the Command code FOS\UserBundle\Command\PromoteUserCommand which uses the FOS\UserBundle\Util\UserManipulator to do actions on the user.
So if you want to modify your User directly in your controller, you can use it, but I don't know if it is the best way to do it. Just call it via your container like this :
/**
* #Route("/user/{id}", name="test_user")
* #ParamConverter("user" , class="MyBundle:User")
*/
public function testUserAction( UserInterface $user )
{
$userManipulator = $this->container->get("fos_user.util.user_manipulator");
$userManipulator->addRole($user,'ROLE_ADMIN');
return new Response();
}
Hope it helps.
