[Samba] samba-tool domain backup online && --configfile

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

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.
