[Zope] Redirect when not authenticated

Hi All, I have a secure directory (no Anon access) and when I access it, it will throw me to a login screen in the GUF folder in that dir. What I really want to happen is for the user to be thrown back up a level to the main login/news etc etc screen which is a better place to start. however I seem to be getting all sorts of security problems. Any ideas anyone? Many thanks Gresh
