Hello Gizmo,
The UBB-threads is a part of a website acting like a corporate intranet. Anonymous users can browse only a part of the site and they cannot view the forum. Only if you are autenticated on the site you can access the forum-link on the site navigation. So autenticated website users are non-authenticated viewers on the ubb-threads. So you need an extra login to post.
On the old server (running classic) this is done this way. If you go to the forum directly(lets say by bookmark), you will be presented with the websites log-in screen (the former programmer went away due to a quarel so i can't ask him how he did it)
I know this sounds complicated Gizmo, but due to sensitive content, this is the way want it. Ans so far it works for them....
Thanx
btw: i guess i can password-protect the forum directory, but thats not the way i like to do it, since the site is running it's own authenication module.
