I am the IT administrator for a group of researchers at a university. I have a non-production SAMBA server that I am suddenly needing to press into  production temporarily

 I have a CentOS6 machine running  winbindd and samba 3.6.23-30.el6_7. User Account Configuration is NIS and Authentication is Kerberos password. I manage my NIS servers but the Kerberos and Active Directory Domain controllers are managed by the University IT organization. My production samba servers are running samba 4.2.10 but the problems there are the subject of a different thread.
I have used the same smb.conf file for years across several versions of RHEL and CentOS and it has worked fine until now.

All users can log in and mount home shares and shares that do not have the "valid users = @group” parameter.  Shares that do have the "valid users = @group” get the following error when trying to mount/map.
"The share does not exist on the server. Please check the share name, and then try again."

Any suggestions on where to go from here?

Here is a sample from the smb.conf file with some info redacted.
