I had the same issue yesterday when I upgraded a NAS on a small branch 
office from samba3 member server to samba4 in order to have on site 
authentication in case or internet failure.

I didn't found anyway to reproduce the same behavior of rid/uid mapping 
of winbind 3.6 with samba4. I gave up quickly as it was not a big deal 
to have different sid/uid mapping on that site. However I'd be glad to 
hear from you if you have found a solution.
