Active Directory Kerberos Server and Windows MIT Tools Client

IIS and other Windows SSPI based applications will only use credentials
that are obtained via the Microsoft logon screen.
You cannot use MIT KfW to obtain a TGT for those applications.   In
other words, you must log onto the machine with the domain account and
not a local account if you wish to use IE.

Your other option is to start IE using "RunAs <domainAcct>" and issue
your username/password for the domain account each time you start IE.

Normally, with a standard Windows XP / Vista client (that is joined to the domain), when I login with a domain account I get a TGT for the AD domain / realm.  This TGT is then used to get tickets for various other services that require Kerberos.  When I run a klist from the MIT tools installed on this client, I show my ticket cache: MSLSA.

I added an AD DC for the Kerberos Server, but I left Domains that map to MYDOMAIN.COM empty (not sure what's supposed to go here).

If I run klist from c:\Program Files\MIT\Kerberos\Bin I get a klist: No credentials cache found (ticket cache API:myuser at MYDOMAIN.COM.  Also, If I try to run IE to hit an IIS web server requiring Kerberos, it still prompts me for my credentials.
> I think I'm almost there - but can someone help me connect the pieces?  Again, I would like to log in to a windows xp / vista computer, enter a username and password to obtain a tgt in the mslsa, so that IE can hit an IIS server that requires kerberos w/o typing in the password again.
