Peter,

I've been asking the same basic question periodically for the last two 
weeks and have not gotten any replies that make things work.  No one has 
volunteered that their Samba NT4 domain works with the new versions.

You could start by looking at the "Winbindd/Netlogon improvements" 
section here: https://www.samba.org/samba/history/samba-4.2.0.html

None of these parameters made any difference for me, but your luck may 
be better than mine.  Additionally, you will face the challenges brought 
on by the security fixes.  It's not looking good for Samba NT4 domains.
