One difference I ran into with samba authentication is in cent 5 /etc/pam.d/system-auth-ac is the file to change but in cent 6 its /etc/pam.d/password-auth-ac. I found that changes I made only to system-auth-ac in 5 had to be made to both system-auth-ac and password-auth-ac in 6. This was to have authentication work for things like ssh and sudo in centos 6.
