You could either use an administrative account which is not a member of 
so many groups (causing the "packet too big" error), or use a more 
recent version of samba.
In any version <= 3.0.22 the tcp fallback is not implemented during the 
kpasswd request. The krb5.conf kdc line is not taken into account at 
this place.
