[Samba] clustered samba registers all non CTDB addresses at WINS server

[Daniel Müller]

But the entry for your ctdb cluster manual in your windows2008 wins. I think
ctdb would be better in a dns ads then in a netbios wins
Environment.

nmbd and wins in the cluster setup is probably not the best tested
scenario...

I'd say that you are right and that we should _only_ register the "cluster
addresses" and not the other autodetected ones.
The problem is that in the cluster setup, samba needs to listen on the
wildcard interface and this defaults to registering all of the found
addresses with WINS.

I would consider the behaviour you describe a bug and think we should fix it
to only register "cluster addresses" if it is set.
