Then you need a variable in smb.conf called dns_domain.

I don't think that adding a value to /etc/hosts is a good way to do this.
/etc/hosts doesn't reflect the current network you're in. And I see e.g. the
problem if you have an entry in /etc/hosts like:
127.0.0.2 rupert.galaxy.site rupert
then it registered 127.0.0.2 as IP address too.

I think you got something wrong. If we can resolve the hostname via dns, then
I assume hostname = machine_name + lp_realm().
According to different Microsoft documents   the fqdn is the
computername and the dns domain. Both can be configured/changed (computer name
tab in system properties).
So I think that it would be the best, if you can't resolve it via DNS (or an
/etc/hosts entry, which will still work with the patch) lets fall back and try
hostname = machinename + realm or if preferred add a new config value "dns

Could you point me to this patch?
