Generate Authentication token and authenticate as a user manually in a controller

Question

I am using Symfony2 and FOSUserBundle . I want to get a user with Doctrine ORM then logging in as it.

$user = $em->getRepository("InoUserBundle:User")->find(10);

// I want the security context as $user

Answer 1

like so:

$token = new UsernamePasswordToken($user, '12345', "admin", $user->getRolesAsArray());
$this->get('security.context')->setToken($token);

$event = new InteractiveLoginEvent($request, $token);
$this->get("event_dispatcher")->dispatch("security.interactive_login", $event);
