/**
* The AbstractAuthenticationListener is the preferred base class for all
* browser-/HTTP-based authentication requests.
*
* Subclasses likely have to implement the following:
* - an TokenInterface to hold authentication related data
* - an AuthenticationProvider to perform the actual authentication of the
* token, retrieve the UserInterface implementation from a database, and
* perform the specific account checks using the UserChecker
*
* By default, this listener only is active for a specific path, e.g.
* /login_check. If you want to change this behavior, you can overwrite the
* requiresAuthentication() method.
