[Samba] Upgraded to 4.8 - forced to use winbindd - retro how to missing?

[Richard Bollinger]

We recently upgraded a test server to samba-4.8.3.... but wonder how to
reproduce the legacy behavior with winbind now forced into the picture for
better or worse.

We specifically do not want any of the whiz-bang capabilities of winbind,
just the old familiar mapping of windows usernames to unix usernames.

It seems not sufficient to omit winbind settings in smb.conf; i.e., the
defaults force the "new and improved" behavior.

Thanks much for your advice.
