I don't think you want KfW at all. XP can get tickets from Heimdal without
KfW. There are two methods (neither of which I'm terribly familiar with
so ...). One is to join XP as a member of a workgroup. That would work
without Samba at all but there will be no LDAP server or RPC services so
there will be no SIDs or any access control to go with. But mod_auth_kerb
would work. The second method is to try to replace the DC with Samba so
that you get LDAP and RPC servers to supply the cental account database
and an experience generally more consistent will regular Windows
networks. In either case I don't think installing additional Kerberos
libs on clients would really do anything for you.
