I've followed the instructions and I've poured through dozens of posts on here and I just can't seem to get AD Auth to work.  I've tried with and without using impersonation.  I'm using the Classic .NET AppPool.  I removed anonymous access on /desktopmodules/authenticationservices/activedirectory/windowssignin.aspx and turned on Windows Authentication, and when I hit it happily taking me to the portal, but it still has the "Register|Login" up in the corner like I'm not logged in.



When I try to manually login with the Windows Login option tells me Login Failed and passwords are case sensitive.



The only thing I'm seeing in the event error is a repeating error about being unable to delete some cache files due to locking.



Any help you guys could give me would be greatly appreciated.

Password is 9 characters.

If I go to the Windowssignin.aspx it forwards me to the portal but it still has "Register|Login" up in the corner like I'm not logged in.

I tried hitting windowssignin.aspx on a non-domain machine and it did pop up the windows login box and it took my credentials but the same deal once I got to the portal.

Thanks,
Isaac

I just double checked and can confirm that the site is running under the Classic .NET AppPool and that the managed pipeline for that app pool is Classic.
