Yep. That works. The more I looked at it, the more impossible it became.

I'm not sure if this file is distro specific. Your comment about
rewriting leads us to think it is. e.g. Ubuntu seems to do smbd, nmbd
and winbind all in the same script:

whereas openSUSE splits winbind off.

In any case, we think it would be pertinent to make a check to see if we
were joining to AD and disable nmbd there and then. If not, nmbd goes
crazy each time smbd is hit. I think this is because the cluster nodes
have the same netbios name.

Anyway, thanks. One step closer to production.
