php - Display authenticated users on non-secure (anonymous) routes -

i use php , silex build web app , implemented basic authentication via securityserviceprovider this:

$app->register(new silex\provider\securityserviceprovider(), array(     'security.firewalls' => array(         'private' => array(             'remember_me' => array(                 'key' => $config['secret_key'],                 'lifetime' => $config['remember_me_duration'],             ),             'pattern' => '^/admin',             'form' => array('login_path' => '/login', 'check_path' => '/admin/login_check'),             'logout' => array('logout_path' => '/admin/logout'),             'users' => $app->share(function () use ($app) {                 // ...             }),         ),         'public' => array(             'pattern' => '^/$',             'anonymous' => true,         ),         'login' => array(             'pattern' => '^/login$',             'anonymous' => true,         ),     ), )); 

as can see /admin paths secured, there can use $app['security']->gettoken()->getuser(); actual user authenticated , display logged in $username, if on /login or / routes user anon. if i'm authenticated.

how can authenticated user, if there one, otherwise anon. string, on / , /login routes in order display message like: logged in $username ?

i tried use is_granted('is_authenticated_fully' function in twig templates check if user authenticated, on /login , / returns false (even if i'm authenticated) since anonymous user takes precedence on authenticated ones, no success here.

everything must under same firewall , have use access control.
