I did some testing, but mostly with the Samba 3 codebase and
the 'net' utility. There were some issues related to which ports were
forwarded, but I'll have to do some more testing to be sure.
(Last time I checked the 'net start/stop' commands were not ported
to Samba4 and its sambatool, but that was a while ago.)
I will look into this!
