samba - Nov 2021 - Using samba-tool to join a linux file server to the domain doesn't appear to work

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.

What version of Samba are you using ?
Your join method only works with Samba >= 4.15.0

Rowland

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
