I see a different solution here:
User authenticate to a Samba controled Domain, and because Samba has the
Kerberos password(=NTPassword hash) it could impersonate the user,
accting to the AFS/Coda cell on behalf of her/him. In this way Samba
could become a gateway between Windows clients and AFS/Coda servers.
Unfortunatelly I don't know how could be that implemented.
