/**
 * 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.
