In version 3.03 (https://github.com/nette/security/releases/tag/v3.0.3) the identity and authenticated state are cached.
But it makes problem if you want to switch between namespaces.

For example in FrontModule\BasePresenter.php:
public function startup()
{
parent::startup();

$this->getUser()->getStorage()->setNamespace('admin');
$id = $this->getUser()->getId();

$this->getUser()->getStorage()->setNamespace('front');
$id = $this->getUser()->getId();

}

It always return ID from "admin" namespace.
