This will hit more than DHCP anyway, as samba_dnsupdate is essentially
doing the same thing. 

That BIND's nsupdate -g works against BIND itself is not supprising, but
there may be some small details we are getting wrong in the internal

So, what I'm suggesting is that someone needs to manaully kinit, and
then manually run nsupdate -g commands and show what bits fail, how they
fail and perhaps work out why they fail.
