[Samba] After joining domain, Samba uses the workgroup name, not the FQDN when running the net ads command

[Jonathan S. Fisher]

Rowland, I hear and understand you loud and clear. If you could point out
below what is the problem, because the client seems to be configured
correctly as you have asked:


root at freeradius:~# nslookup 192.168.127.131
Server: 192.168.127.131
Address: 192.168.127.131#53

Non-authoritative answer:
131.127.168.192.in-addr.arpa name = whiskey.windows.corp.XXX.com.

Authoritative answers can be found from:

root at freeradius:~# nslookup 192.168.112.4
Server: 192.168.127.131
Address: 192.168.127.131#53

Non-authoritative answer:
4.112.168.192.in-addr.arpa name = wine.windows.corp.XXX.com.

Authoritative answers can be found from:

root at freeradius:~# cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by
resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 192.168.127.131
nameserver 192.168.112.4
search windows.corp.XXX.com

Both of those are DCs, both of them resolve correctly forward and reverse,
and both of them are in resolv.conf... is this incorrect yes/no?
