Yes to the latter.

Can you list the shares with:

smbclient -L //smb_srv-ip_address -U doug

Can you log into doug's home share with:

smbclient //smb_srv-ip_address/doug -U doug

AFAIK, you need machine accounts when you set "domain logons = yes"
because the samba server acts as a DC; and you have both "domain
logons = yes" and the "server role = classic primary domain
controller" set.

What's the output of "pdbedit -L" on 14.04 and 16.04? Are machine
accounts (ending with "$") listed?

You have "add machine script = ..." in your smb.conf to create a unix
machine account automatically if it already has a samba machine
account so you must (?) have some.
