Will IE send a Kerberos ticket if not in a Domain?

http://serverfault.com – I'm trying to test a Kerberos-based SSO solution for our Java app. Unfortunately, I don't have a Windows domain at my disposal to do so. I read about the ability to integrate Windows with a standalone, non-Microsoft Kerberos KDC: http://technet.microsoft.com/en-us/library/bb742433.aspx#EDAA ...so I set up a Kerberos server on Ubuntu and integrated a couple of Windows boxes (one Win 7, one XP) with it using the ksetup.exe utility. I'm now able to log into the Kerberos realm on these PCs. However, when I connect to our web app, IE doesn't offer to send a Kerberos ticket to the server...only N (HowTos)
