[Samba] Using samba-tool to join a linux file server to the domain doesn't appear to work

[Patrick Goetz]

And ...

The old syntax however does work!

root at data2:/etc/samba# net ads join -U administrator
Enter administrator's password:
Using short domain name -- EA
Joined 'DATA2' to dns domain 'ea.linuxcs.com'


root at samba-dc:~# host data2
data2.ea.linuxcs.com has address 192.168.1.81

root at data2:/etc/samba# systemctl start winbind
root at data2:/etc/samba# systemctl status winbind
