I downloaded UCS5 and tried to install it in a VM. The first attempt
failed when I tried to set up a DC, there is (apparently) no way to
change the dns and when it did finish the set up, there was no Samba!

Second attempt, I went for what it described as a join to Active
Directory, I ended up with what I call a Unix domain member, but with
what I would call a borked smb.conf, it was using the ldap backend for
the '*' domain and the nss backend for the 'DOMAIN' domain. There were
numerous other parameters that I wouldn't use.

All in all, I wouldn't recomend UCS5 to my worst enemy, but this is
just my personal opinion.
