Sonata Admin: isGranted() always returns true in Admin class, but correct boolean in template

I'm using SonataAdminBundle and SonataUserBundle in a Symfony 2 project. The installed packages are:

$ composer show | grep symfony

sonata-project/user-bundle               2.2.5              Symfony SonataUserBundle

The roles in the security.yml configuration file:

role_hierarchy:
    ROLE_ADMIN:       [ROLE_USER, ROLE_SONATA_ADMIN]
    ROLE_SUPER_ADMIN: [ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]

Logged in with a user that has ROLE_ADMIN only, the following dumps from my UserAdmin class:

dump($this->isGranted('ROLE_ALLOWED_TO_SWITCH'));
dump($this->isGranted('ROLE_BLA_BLA_BLA'));
dump($this->isGranted('ROLE_USER'));

print in Symfony toolbar (on dev environment)

true
true
true

While if I put the dumps in an overridden Sonata template like app/Resources/SonataAdminBundle/views/CRUD/[anytemplate].html.twig,

{{ dump(is_granted('ROLE_ALLOWED_TO_SWITCH')) }}
{{ dump(is_granted('ROLE_BLA_BLA_BLA')) }}
{{ dump(is_granted('ROLE_USER')) }}

the correct values are returned.

false
false
true

I got into this because this line here, in SonataUserBundle, had no effect: https://github.com/sonata-project/SonataUserBundle/blob/3.x/Admin/Model/UserAdmin.php#L95

The isGranted() usage is described here: http://symfony.com/doc/current/bundles/SonataAdminBundle/reference/security.html#usage

Am I doing something wrong or is this a bug?

Edit:

Thanks to @mickadoo's comment I noticed that I had the default handler sonata.admin.security.handler.noop, which is said to always return true, whatever that means. I set it up with sonata.admin.security.handler.role and created some roles (ROLE_SONATA_USER_ADMIN_USER_LIST and ROLE_SONATA_USER_ADMIN_USER_VIEW) and now it returns the correct value for $this->isGranted('LIST') or $this->isGranted('VIEW'), but always returns false for $this->isGranted('ROLE_USER') or $this->isGranted('ROLE_ALLOWED_TO_SWITCH').

How can I check this roles?

Generic, non-entity roles, like ROLE_USER, ROLE_ADMIN, ROLE_SUPER_ADMIN, ROLE_{CUSTOM_STRING} should be checked using the default Symfony security context.

In the Admin class:

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

if ($securityContext->isGranted('ROLE_USER')) {
    // Your PHP code here
}

In Twig template:

{% if is_granted('ROLE_USER') %}
    Your HTML/Twig content here.
{% endif %}

Entity actions roles like ROLE_SONATA_USER_ADMIN_USER_LIST, ROLE_SONATA_USER_ADMIN_USER_VIEW, ROLE_{CUSTOM_SONATA_ADMIN_SERVICE_NAME}_{ACTION} can be checked using the Sonata Admin helper or the Symfony security context.

In the Admin class:

// Using Symfony security context
$securityContext = $this->getConfigurationPool()->getContainer()->get('security.context');

if ($securityContext->isGranted('ROLE_SONATA_USER_ADMIN_USER_LIST')) {
    // your code here
}

// Using Sonata helper for shorter syntax
if ($this->isGranted('LIST')) {
    // your code here
}

In Twig template:

<!-- Using Symfony security context -->
{% if is_granted('ROLE_SONATA_USER_ADMIN_USER_LIST') %}
    Your HTML/Twig content here.
{% endif %}

<!-- Using Sonata helper -->
{% if admin.isGranted('LIST') %}
    Your HTML/Twig content here.
{% endif %}
