samba - Jul 2019 - samba-tool domain backup online && --configfile

On
https://wiki.samba.org/index.php/Back_up_and_Restoring_a_Samba_AD_DC#Online_DC_backup
there is a comment ?you may want to specify a --configfile option so that the
correct smb.conf settings get included in the backup.?
Why does samba-tool not pick up the one it (or other parts of Samba) is compiled
with automatically? Like `smbd -b | grep "CONFIGFILE" | sed -n -E
's/CONFIGFILE:(.*)/\1/p' | xargs` ?

The important point is the prefix to that sentence: "This command can be
run locally on the DC or remotely. If running the command remotely, you
may want to specify a |--configfile| option".

You can run the online backup on any machine with samba installed, as
long as you provide the admin credentials. You do not *have* to run it
on the DC itself. If you run the command remotely, the smb.conf file
might not exist on that machine, or it might be the vanilla/default
smb.conf, rather than the one used for your domain.

The point is the backup might still succeed in this case, but the tool
won't be able to magically guess all your smb.conf settings correctly.

Hi Tim,
then I believe there is a bug. I did not specify the option and it used
/etc/smb.conf rather than the correct /etc/samba/smb.conf. I was running a local
backup on DC with Louis build 4.10.6 on ubuntu 18.04.2.
Shall I open a ticket?
Best Regards, Joachim
