Problem with session in security plugin

Hi, I have a problem with "remember me" function. When user click remember me during login then is setup cookie in that way:

$this->cookies->set('user_id', $user->user_id, time() + 15 * 86400);

ok, next if user close browser and open again, system correctly read cookie, set to session user object:

$this->session->set('user', $user);

and redirect to main page.

I also implemented SecurityPlugin like in Invo example:

if (!$this->session->user) { //redirect to login page }

I tried to dump session in SecurityPlugin and its empty.

My index.php define session nad security plugin in that way:

$di->setShared('session', function () {
    $session = new \Phalcon\Session\Adapter\Files(array(
        'uniqueId' => 'custom-service-id'
    ));
    $session->start();
    return $session;
});

  $di->set(
    'dispatcher',
    function() use ($di) {
        $eventsManager = $di->getShared('eventsManager');

        $eventsManager->attach(
            'dispatch:beforeException', new ErrorPlugin()
        );

        $eventsManager->attach(
            'dispatch:beforeDispatch', new SecurityPlugin()
        );

        $dispatcher = new Dispatcher();
        $dispatcher->setEventsManager($eventsManager);
        return $dispatcher;
    },
    true
);

And what happend? Infinity loop ;), user from login page is redirect to main page, from main page to login page, etc.

Any idea?
