Silex中的WebProfiler不显示用户

I've integrated silex/web-profiler in a Silex app:

"require-dev": {
    "silex/web-profiler": "^2.0"
}

and configured an example firewall with form authentication:

// Security
$app['security.firewalls'] = array(
    'main' => array(
        'pattern' => '^/',
        'anonymous' => true,
        'form' => array('login_path' => '/login', 'check_path' => '/login_check'),
        'users' => array(
            'admin' => array('ROLE_ADMIN', '$2y$10$3i9/lVd8UOFIJ6PAMFt8gu3/r5g0qeCJvoSlLCsvMTythye19F77a'),
        ),
    )
);
$app->register(new Silex\Provider\SecurityServiceProvider(), array());

// Profiler
if ($app['debug']) {
    $app->register(new Silex\Provider\ServiceControllerServiceProvider());
    $app->register(new Provider\WebProfilerServiceProvider(), array(
        'profiler.cache_dir' => __DIR__.'/../cache/profiler',
        'profiler.mount_prefix' => '/_profiler', // this is the default
    ));
}
$app->boot();

I'm able to login with the example admin account and access the user in a controller, but the WebProfiler doesn't show the user tab:

Should it be additionally configured?

It seems that in order to show the security panel with the user information in the web debug toolbar you need to install also the security bundle (where the SecurityDataCollector class resides).

So you just need to execute:

composer require --dev symfony/security-bundle

And that should be enough.
