It won't show a login form if apache is correctly configured as there
should be no way to pass through apache if you are not authenticated.

As the auth code is shared with all the other authentication mechanisms,
and is already complex enough, there is nothing in the UI that manage that
case.
In that case of apache misconfiguration, it will just show the login form.
