Did you build Samba with MIT Kerberos support or use package so built? 
If not, then perhaps you have the wrong KDC started, just start Samba
and it will handle the rest.

If that isn't it, try re-building the AD DC without MIT Kerberos, we
have some reports of issues in this area, and it would provide a point
of comparison we can investigate.
