Thank you, I didn't realize the version of Samba was so old, in the Ubuntu
18 repos. I found a different PPA and upgraded to 4.10.8. After restarting
the service, it created the folder.

I use Webmin to manage DNS, so one thing I'm confused about is, will Samba
be adding the zones so they will be manageable by bind and Webmin or will I
have to use samba-tool to manage the local AD's DNS? Samba isn't creating
zone files, like Bind, they don't show up in Bind's Webmin module and I
can't find any files that are being created by Samba that look like Bind's
zone files.
