The version of samba that comes with Ubuntu 16.04 is very old (4.3.11) and
the offline login feature for winbind simply doesn't work. I'm not sure if
it's fixed in newer versions or not as I'm still on Ubuntu 18.04 (samba
4.7.6) which also doesn't work. If you are only using it to authenticate
to an AD controller, you should switch to using sssd. I have multiple
clients that can be offline from a server for months at a time, and sssd
has never let me down. Winbind unfortunately isn't up to that task (at
least not with older versions).
