samba - Jan 2017 - Upgrade from 3.6.9 to 3.6.23 - Lost authentication

After attempting to upgrade to version 3.6.23 I discovered
that I was unable to authenticare against another Samba server
running as a PDC and using winbind.

Due to time constraints, I erased the samba setup and
reinstalled version 3.6.9.  Everything went back to normal.

Is this a bug or did something on the configuration side
change?

There may have been configuration changes, you would have to read the
release notes, see here:

If it is a bug, you have no chance of getting it fixed, 3.6.x went EOL
in 2015, see here:
