public interface AuthenticationFailureHandler
 Typical behaviour might be to redirect the user to the authentication page (in the case of a form login) to
 allow them to try again. More sophisticated logic might be implemented depending on the type of the exception.
 For example, a CredentialsExpiredException might cause a redirect to a web controller which allowed the
 user to change their password.
