QAS: Problems after upgrading to Samba 3.6 and subsequently Samba 4.2

Hello,

I have a CentOS 6.7 box that was recently upgraded to run Samba 3.6 ( I know, I know, we're behind the ball).  After the upgrade, the shares on the server no longer worked.  

I ended up upgrading to samba 4.2.10.  After running the vas-samba-config, I am closer to succeeding.  However, it looks like there is an issue with the quest LDAP server.  The error I am getting is:

winbindd[xxxx]: failed to bind to server ldap://localhost/ with dn="[Anonymous bind]" Error: Can't contact LDAP server

Unfortunately, this is a system that doesn't touch the internet, so logs are hard to come by. 

I'm not sure where or why it is trying to make an anonymous bind.  I specified the ldap admin dn = CN=VasIdmapAdmin line in the smb.conf file.

Any help would be greatly appreciated.
