Its sounds like your entry point is missing the following pam line:

session    required     pam_loginuid.so

This sets the loginuid which is inherited by each process the user creates. 
So, if they get in by gdm, it needs to be in gdm's pam stack. If they get in 
by sshd, it needs to be there. Etc.
