We have configured our DNN 4.3.7 framework afresh in our Windows 2003 server. We haven't even done any change after the installation. We are trying to configure Single-signon with ADSI authentication. (We referred this URL: http://www.dotnetnuke.com/Community/ForumsDotNetNuke/tabid/795/forumid/89/threadid/73214/scope/posts/Default.aspx).

Now the sigle-signon seems to behave wierd. At times, it works - at times it is not.

What we want to achieve here is:
1. Allow the user in the AD domain to access the DNN portal with single-signon (no separate login for DNN portal).
2. Redirect the user to a different page based on certain conditions after the user logins.
3. Also we don't want to automatically create the user if the user is not registered in the DNN portal.

Kindly throw some light on how we can achieve these tasks.
