I guess I will do some more reading.

Unless QNAP has their own utility similar to sssd, I can absolutely *mount*
a share AND *login* into the NAS device using my AD credentials. That is
The mount command I printed above is the exact line I'm using and I specify
"user=" and "domain=" options parameters.

Honestly, you should have both IMO. This is even true in the Windows world
and a lot of filers (NetApp for instance creates it's own domain so the
administrator account is technically NETAPP/admin or something of that ilk).

Well it's a bit more complicated then that. They have an AD wizard you go
through that joins the NAS device to your domain (that worked after a
change on my end).

Not according to their extensive doc. These filers are suppose to work as
bona fide CIFS file servers connected to AD (and are heavy users of samba).
Antyway, Rowland, don't get upset at me. I did actually Google A LOT before
asking all of the above.
So it seems that to get samba to know who is mounting what I need to add a
few lines to tell it about my domain.
