[Samba] Is it EVER needed to set up kerberos manually if you use samba to join an ADS domain as a domain member?

Hence this is why I started this topic, because if you look on the net nine
tutorials out of ten (ok that was a blatant lie, but close to truth) state
that you have to manually set up kerberos.
I think that is ridiculous yet I have been told that I have to do it "in
case" and I say: IN CASE OF WHAT???? And I never get a straight answer, or
one thant I can disprove because no examples are given.

So I started this thread...

Please continue on!
