I followed the steps outlined in the sticky posts and have AD authentication working correctly if I enter my username/password in the username/password form.  However, if I browse directly to the WIndowsSIgnIn.aspx file (after removing anonyous access rights), the page just refreshes without logging me in or displaying an error message.

I have tried this with the DotNetNuke.HttpModules.AuthenticationModule both commented and uncommented.    I have tried putting the site in the trusted and intranet zones but since I am not getting an IE username/password window I don't think that is the problem.

Does anyone have any suggestions?

That was the problem.  When I changed it in the DB from domain\username to DOMAIN\username it started working so I have a couple of questions.

I saw in another post that a change was needed in the compare logic to be case insensitive.  Is that a change I can make or do I have to wait for a hotfix?

Looks like if users are created automatically, it isn't an issue so I can probably live with it.

Thanks for pointing me in the right direction,

Dan
