[Samba] samba-tool gpo listall error

Mon Nov 16 19:36:07 UTC 2020

Hi Louis,

Took me a bit to get around to this. That solves the problem. Now the
samba-tool gpo listall works.

Now can you explain how to make this work with systemd-resolved? The main
reason that I want to do this is because Ubuntu (and many other
distributions) have moved toward this. That way system updates and upgrades
are less likely to break the installation.

Thanks,
Jonathan Kreider
