Nothing there that I can see (/var/log/secure in fc17).

It does not look like it is a problem in gdm alone, I just decided to 
give up on gdm and tried kdm, but it exhibits the same behavior (open 
session script gets called, close session script is ignored).

I did some find/grep in the source of gdm yesterday and did not find pam 
stuff. It does not look like gdm itself is dealing with pam directly. 
How does the "chain of command" work these days?
