Symfony Security rout admin

我想要受保护的url / admin /并且我使用symfony书但不能正常工作，我有用户不是用户捆绑只是实体用户和字段角色= ROLE_ADMIN或ROLE_USER，ROLE_FREELANCER . 我有标准完整的SecurityBundle . 现在，如果我与拥有ROLE_FREELNANCER的开发者一起进入，我会为此角色进行操作，但如果我通过url admin / tim / dashboard这个开发人员输入此URL，则此错误 . 请帮忙 . 这是我的安全：

和我的行动

class SecurityController extends Controller
{
  public function loginAction(Request $request)
  {

    $authenticationUtils = $this->get('security.authentication_utils');

    // get the login error if there is one
    $error = $authenticationUtils->getLastAuthenticationError();

    // last username entered by the user
    $lastUsername = $authenticationUtils->getLastUsername();

    return $this->render('ArtelProfileBundle:Security:login.html.twig',
        array(
            // last username entered by the user
            'last_username' => $lastUsername,
            'home_page' => $this->container->getParameter('home_page'),
            'phone_in_header' => $this->container->getParameter('phone_in_header'),
            'error'         => $error,
            'db_url' => $this->container->getParameter('db_url'),
            'api_url' => $this->container->getParameter('api_url'),
            'mauth_url' => $this->container->getParameter('mauth_url'),
            'gaID' => $this->container->getParameter('gaID'),
            'ymID' => $this->container->getParameter('ymID')
        )
    );
}

public function securityCheckAction()
{
    // Роут
}

public function indexAction()
{

    $securityContext = $this->container->get('security.context');

    if ( $securityContext->isGranted('IS_AUTHENTICATED_FULLY') == false ) {
        return $this->redirect($this->generateUrl('login_route'));
    }

    $role = $this->getUser()->getRoles();
    if($role[0] == 'ROLE_FREELANCER')
    {
        return $this->redirect($this->generateUrl('artel_profile_homepage', array('username' => $this->getUser()->getUsername())));
    }
    elseif($role[0] == 'ROLE_COMPANY')
    {
        return $this->redirect($this->generateUrl('artel_user_profile_homepage', array('username' => $this->getUser()->getUsername())));
    }

    if($role[0] == 'ROLE_ADMIN')
    {
        return $this->redirect($this->generateUrl('admin_tim_dashboard'));
    }
    else

    return $this->render('default/index.html.twig');
