Today's security patches for Samba 4.4.2 and 4.3.8 break logins from Mac clients when the server is running in security = ads mode. The same smb.conf in 4.3.6 allows logins just fine.
Mac client is OSX 10.10.5
Server is Samba 4.4.2 and 4.3.8
AD domain is 2008-R2
Log for an affected client is attached.
I'm also receiving reports from another admin here that Windows server 2008-R2 is affected as a Samba client.

You need to run winbindd on your Samba server.
Running winbindd seems to fix the issue. Thank you.
