Cumulative issues with Windows Authentication

Hello,

I just downloaded 8.06 and installed it and am having some fits with Windows Authentication.

I changed the statement to TRUE in the functions/functions_windows_authentication.asp and disabled Anonymous Authentication to the Forums directory and enabled Integrated Authentication.

I had the SQL DB on a SQL2005 box and am using the SA account for connection. I am able to create the db and run the config script. I open the admin.asp page with my domain admin account and log in with the administrator info from the documentation.

However, I cannot change the group membership of my domain account while logged in as the administrator.

Also, whenever I try accessing the site with another domain account, the account creating fails with a SQL error.

I decided to try using SQL2000 as the backend and the account creation seems to work. However, when you initially access the site, you get the Quick Login field at the upper right and when you enter your domain credentials it fails and loads another login page. Continuing to submit credentials does not work. However just hitting back to the main page, removes the Quick login field and the user is correctly logged in. This seems to be described in post: http://forums.webwiz.net/forum_posts.asp?TID=23389

With this current setup, seems like most of the functions work, but I still cannot edit user group memberships. I am getting an error like this person described: http://forums.webwiz.net/forum_posts.asp?TID=23468&KW=windows+authentication

In my searching I think someone mentioned a cookie issue? If anyone can shed some light on this it would be much appreciated.  Awww man... I thought I had part of it solved here: 

p.s. Also, I can't seem to find any more info regarding this post: http://forums.webwiz.net/forum_posts.asp?TID=22616&KW=email+address+info

I would definitely be interested in something that pulls more info from Active Directory.

Thanks in advance.
