Can you show us the pam.d files? They are still the most likely culprit.

If anything has setlogmask your log output might be dropped. (I don't 
know if gdm does this.)

BTW: You should not call openlog/closelog in a pam_module. The calling 
process may have called openlog itself and that choice should prevail.
