Greeting,
I'm trying to figure out how to use GPOs in my samba AD. There's an
awful
lot that I don't know. But along the way of learning I found this:
https://wiki.samba.org/index.php/GPO_Backup_and_Restore
And I decided to try the "samba-tool gpo listall" command that I found
there to confirm that samba thinks it has the GPOs that I think it does.
But I get this error:
root at ad2:~# samba-tool gpo listall
ERROR(runtime): uncaught exception - ('Could not find a DC for domain',
NTSTATUSError(3221225524, 'The object name is not found.'))
File "/usr/lib/python3/dist-packages/samba/netcmd/__init__.py", line
186,
in _run
return self.run(*args, **kwargs)
File "/usr/lib/python3/dist-packages/samba/netcmd/gpo.py", line 464,
in
run
self.url = dc_url(self.lp, self.creds, H)
File "/usr/lib/python3/dist-packages/samba/netcmd/gpo.py", line 128,

dc_url
raise RuntimeError("Could not find a DC for domain", e)
I'm using Louis' packages...
root at ad2:~# smbstatus
Samba version 4.11.13-Debian

I've upgraded to 4.11.16 and the problem remains:

root at ad2:~# smbstatus
Samba version 4.11.16-Debian
I thought it might be DNS, but ping works:
root at ad2:~# ping ad2
PING AD2.samdom.com (192.168.1.12) 56(84) bytes of data.
64 bytes from AD2.samdom.com (192.168.1.12): icmp_seq=1 ttl=64 time=0.067 ms
Where should I look next?
Thanks,

Does the DC point to itself as the first nameserver in /etc/resolv.conf ? Rowland
More problems... So cat /etc/resolv.conf yields nothing. root at ad2:~# ll /etc/resolv.conf lrwxrwxrwx 1 root root 39 Jun 17 2018 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf Shows a broken link. Since this is Ubuntu 18.04 with systemd and the stub-resolv.conf missing, I'm lost. I'll test my google fu to try to figure this out, but if someone can point me in the right direction, I'd be most grateful. I presume that the python code gets its info from /etc/resolv.conf rather than a DNS query? (Since ping works...)
