I am having some trouble with login and authentication in Symfony2. The exception is "$user must be an instanceof UserInterface, an object implementing a __toString method, or a primitive string."
Debugging my code I could notice that the user I am trying to log in my application can get authenticated successfully (app/log/dev.log) but the credentials var is null:
The user variable from AbstractToken has the user data from database.
I continue debugging in the ContextListener->refreshUser function and I get these values:
Everything has the value null and on the Symfony\Bridge\Doctrine\Security\User\EntityUserProvider->refreshUser function returns the variable $refreshedUser as null, so when the function $token->setUser($refreshedUser) on the ContextListener class fails and throws the exception.
I write down my security.yml and my entities I am using:

The UsuarioRepository where I implements the three functions loadUserByUsername, refreshUser and supportsClass:
class UsuarioRepository extends EntityRepository implements UserProviderInterface
{
public function loadUserByUsername($username)
{
$q = $this->createQueryBuilder('u')
->where('u.username = :username')
->setParameter('username', $username)
->getQuery();
try {
$user = $q->getSingleResult();
} catch (NoResultException $e) {
$message = sprintf('Unable to find an active Usuario object identified by %s', $username);
throw new UsernameNotFoundException($message, 0, $e);
}
return $user;
}
public function refreshUser(UserInterface $userInterface)
{
$class = get_class($userInterface);
if (! $this->supportsClass($class)) {
throw new UnsupportedUserException(sprintf('Instances of %s are not suppoted', $class));
}
}
public function supportsClass($class)
{
return $this->getEntityName() === $class || is_subclass_of($class, $this->getEntityName());
}
}
Thank you for your help.
Kind regards.
P.S: I am using Symfony 2.5.6
