Permanent login does't work

Hello!
I used sandbox and because I have only private part of system (only logged users can see pages), all presenters inherits from BaseSecuredPresenter:

	public function startup() {
		parent::startup();

		if (!$this->user->isLoggedIn() && $this->getName() !== "Sign" && $this->getAction() !== 'In') {
			$this->redirect("Sign:in");
		}
	}

SignPresenter is more or less from sandbox:

	public function signInFormSucceeded($form, $values)
	{
		if ($values->remember) {
			$this->getUser()->setExpiration('14 days', FALSE);
		} else {
			$this->getUser()->setExpiration('20 minutes', TRUE);
		}

		try {
			$this->getUser()->login($values->username, $values->password);
			$this->redirect('Viz:show');

		} catch (Nette\Security\AuthenticationException $e) {
			$form->addError($e->getMessage());
		}
	}

In config.neon is:

	session:
		expiration: 14 days

Problem is, that system kicks me out after more or less 30 minutes of inactivity. But ini_get('session.gc_maxlifetime') == 1209600, PHPSESSID cookie has expiration in 14 days and $this->user->getLogoutReason() == NULL. Working on Debian/apache on localhost.

Can someone tell me what I'm missing?

Thanks a lot!
