How to use the AccessDecisionManager in Symfony2 for authorization of arbitrary users?

Question

I\'d like to be able to verify whether or not attributes (roles) are granted to any arbitrary object implementing UserInterface in Symfony2. Is this possible?

Maybe you can instantiate a new securityContext instance and use it to check if user is granted :

$securityContext = new \Symfony\Component\Security\Core\SecurityContext($this->get('security.authentication.manager'), $this->get('security.access.decision_manager'));
$token           = new \Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken($user, null, $this->container->getParameter('fos_user.firewall_name'), $user->getRoles());
$securityContext->setToken($token);
if ($securityContext->isGranted('ROLE_ADMIN')) {
    // some stuff to do
}
