[Samba] How do I disable kerberos?

[jimc]

HI.
I have been told that kerberos cannot be running while samba4 is. How do 
I do this? I seem to have missed this on the how-to and system requirements.

I have commented out every entry in /etc/services that seems even 
remotely kerberosish. I still get errors on kinit and host (from the 
how-to).

I have googled until my computers are laughing at me and have posted on 
every forum I can find.

Help? Please?
