I've got my Apache server running, and I have Kerberos configured to integrate with our primary domain controller (Windows 2003).

When I try to access my page, however, I get a login prompt... Which I shouldn't, since this is supposed to be a SSO...

When I manually enter my credentials, it works and takes me to the page. However, I'd like this to use Integrated Windows Authentication.

I had this working at one point, but it doesn't work anymore... :S

Here are my config files.

WHAT AM I MISSING!!! I'm this close to getting it, I can feel it! All I need is to make to login prompt disappear, and for the credentials to be passed automatically.

Thanks for your time.
