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

[Patrick Goetz]

Looks like I need to re-architect the whole system to use an internal 
DHCP server, because setting a static IP on the host appears to be 
causing issues:

root at data2:/etc/samba# samba-tool domain join ea.linuxcs.com MEMBER -U 
administrator
Password for [EA\administrator]:
Joined domain EA (S-1-5-21-2398640129-655337111-1434392923)

However, the host isn't known to the samba DC:

root at samba-dc:~# host data2
root at samba-dc:~#


and the winbind service won't start:

root at data2:/etc/samba# systemctl start winbind
Job for winbind.service failed because the control process exited with 
error code.
See "systemctl status winbind.service" and "journalctl -xe" for details.
