Zend\Session\Container Session validation failed e

Question

I'm trying to use authentication and sessions in a ZF2 App. So far I have the follow code:

In my Module.php:

// (...) rest of code

public function getServiceConfig()
    {
        return array(
                'factories' => array(
                        // (...) Other factories

                        // Authentication Service
                        'AuthService' => function($sm) {
                            $dbAdapter           = $sm->get('Zend\Db\Adapter\Adapter');
                            $dbTableAuthAdapter  = new DbTable($dbAdapter,
                                'sec_user','login','password');

                            $authService = new AuthenticationService();
                            $authService->setAdapter($dbTableAuthAdapter);

                            return $authService;
                        },
                ),
        );
    }

// (...) rest of code

Then in my Controller Login action I have:

use Zend\Session\Container;

// (...) rest of code

    public function loginAction()
    {
       $this->getAuthService()->getAdapter()
                  ->setIdentity('testlogin')
                  ->setCredential('testpass');

        $auth_result = $this->getAuthService()->getAdapter()->authenticate();

        if ($auth_result->isValid()) {
            $session = new Container(); // Exception line
            $session->login = 'testlogin';

            // (...) other code
        }
    }
// (...) rest of code

The code works fine, validate the credentials successfully but when I try to save some value to SESSION with the simplest example I found in documentation, it fails. The line:

$session = new Container();

Is triggering this Exception:

Session validation failed

What else can I test? Any idea about what I'm doing wrong will be appreciated.

Bellow is the full trace:

Attaching an event listener to listen to all events triggered by all classes $sharedEvents->attach('*', '*', .. ) will cause this error message.

You have to be really careful what you attach listeners to, since some listeners are expecting a specific response (in this case a boolean indicating if session is valid). A listener that wasn't designed to handled the event, such as a log listener, will typically not return a response, which in this case is seen as a validation failure.
