[Samba] net ads join disable dns update

[David Roid]

Been there:
1. Compile Samba by yourself, remove WITH_DNS_UPDATE flag.
2. Disallow "allow insecure update" from DNS server.
3. Edit /etc/hosts, use shortname for your Samba server, then upon "net ads
join
" it will complain domain name not found hence will not update DNS.

Cheers
