[Samba] No logon servers avaialbe

We applied latest MS security patches on our Windows 2008 R2 domain 
controllers.  That had unexpected consequence of breaking all our Samba 
servers.  They no longer can authenticate with our domain controllers.  
Looking into this we think it has to do with the BADLOCK security patch.

We tried installing the latest Samba, version 4.4.5 which is supposed to 
be patched for the BADLOCK, but it is still unable to authenticate with 
AD.  Error on windows is "no logon servers found".

So just checking if anyone else has run into this and found a solution?


     workgroup = ENGR_DOM
     server string = Web Server
     security = DOMAIN
     passdb backend = smbpasswd
     map untrusted to domain = Yes
     log level = 1
     log file = /var/log/samba/logs/log.%m
     name resolve order = host bcast
     unix extensions = No
     keepalive = 0
     max open files = 10000
     socket options = TCP_NODELAY SO_KEEPALIVE
     load printers = No
     dns proxy = No
     lock spin time = 3
     idmap config * : range =
     idmap config * : backend = tdb
     strict locking = No
