WebTestCase::loginAs() not working

Hello, I followed the guide to authenticate using WebTestCase::loginAs() but it's not working and it's redirecting me to the login page.

This is my config_test.yml:

imports:
    - { resource: config_dev.yml }

framework:
    test: ~
    session:
        # handler_id set to null will use default session handler from php.ini
        handler_id:  ~
        storage_id: session.storage.mock_file
        name: MOCKSESSID
    profiler:
        collect: false

web_profiler:
    toolbar: false
    intercept_redirects: false

swiftmailer:
    disable_delivery: true

liip_functional_test:
    cache_db:
        sqlite: liip_functional_test.services_database_backup.sqlite

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver:   pdo_sqlite
                path:     "%kernel.cache_dir%/test.db"
security:
    firewalls:
        main:
            http_basic: ~

And this is the test:

class DivisionControllerTest extends FixtureWebTestCase
{
    public function testDivisionList()
    {
        $this->loginAs($this->fixtures->getReference('admin-user'), 'main');
        $client = $this->makeClient();

        $crawler = $client->request('GET', '/teachers/divisions/list');

        // successful
        $this->isSuccessful($client->getResponse());

        // more than 1 division
        $this->assertGreaterThan(
            1,
            $crawler->filter('tr')->count()
        );
    }
}

And this is the log:

[2019-01-16 12:49:32] request.INFO: Matched route "teacher_division_list". {"route":"teacher_division_list","route_parameters":{"orderBy":"name","_controller":"AppBundle\\Controller\\DivisionController::listAction","_route":"teacher_division_list"},"request_uri":"http://localhost/teachers/divisions/list","method":"GET"} []

Hello, any news on this subject? Thanks!

No, sorry, is the problem still here with the 3.x branch?

Got same problem here .. We got 302 redirection (due to Access Denied)

Is it working for you if you follow the redirect?

$client->followRedirects();

I just got into the same issue. With auto-follow the client goes to the login page, gets authenticated and redirected back. So the tests succeeds, but this feels weird.
