Samba 3 Problem with NT Users

I have installed Fedora RC2 with all of the updates and Samba Version 3.0.6-2.fc2.  Below is a copy of my smb.conf file.  I was able to add the computer to the domain with out problem.  When I issue a wbinfo -u or -g I get all of the expected output.  The strange thing is when I try to use getent passwd some users(NT Users) get the expected output other users do not get anything returned.  For the users that I do get information back with using the wbinfo I am able to chown files/directories to their user name and NT user groups and they show up properly when browsing the "Network".  Hope someone can shed some light on this for me.

Thanks
