What version of Samba are you using ?
Your join method only works with Samba >= 4.15.0

Good catch. I've been configuring too many systems and somehow forgot to 
add Louis' PPA to /etc/apt/sources.list.d  <:(

Ugh, I'm an idiot. Can I just upgrade Samba in place, already joined to 
the domain, or is it safer to unjoin, update Samba, and then rejoin?

If the latter, how do I unjoin a linux host?  With Windows you just 
switch the configuration back to WORKGROUP. I've already tested this. 
The DC seems to remember the W10 host for a while after I leave, but 
then forgets about it at some point.
