[Samba] Fwd: Samba AD DC tries to start and fails on reboot

Fri Sep 18 16:24:45 UTC 2020

Hi Louis,

It _is_ now working. I can stop and restart the container and samba comes
up.

However, I've not changed anything to my knowledge. The only thing that
I've done is disabled and enabled the samba-ad-dc.service once or twice in
fiddling around with this.

Perhaps that was enough to get systemd to realize that it really did need
to wait until the network was up before trying to start samba. As I said
before, once the system is up, I can start samba with no problems.

As to dhcp, I suspect that I'm using dhcp on ipv6 b/c I've certainly not
set up any static settings. IPV6 is there, but I've not figured out how to
bend it to my will (or even what my will is) yet.

Thanks,
Jonathan Kreider
