You are logging into a domain joined machine as a local user and then 
wonder why you are having problems ?

Unless the user is root, there is a line like this in the smb.conf 
'username map = /etc/samba/user.map' and the 'user.map' contains '!root 
= DOMAIN\Administrator', where 'DOMAIN' is your netbios domain.

It should work on 16.04, try sorting the above problem out first.
