Theory of operation

BaconAuthentication comes with an authentication service interface (BaconAuthentication\AuthenticationServiceInterface), which defines two methods. The first one being authenticate($request, $response), which tries to authenticate the current request. This method is used for both processing current input from the user (e.g. a login form), as well as retreiving the currently authenticated subject. The return value of this method will always be a result object.

The other method is resetCredentials(), which will simply remove all persisted information and thus make the authenticated subject anonymous again.
