Thanks for the advice, sounds like the right solution[*]. I managed
to get pam_script going. Right now it is at the end of postlogin in
/etc/pam.d/ (after several earlier choices) and it works. Half of
the time. Literally. The open session script triggers with a gdm
login into a gnome session, but the close session script does not
trigger with a logout.
But both scripts trigger on ssh logins and logouts. Systemd seems to
to be happy (at least I see messages in dbus-monitor). But pam,
somehow, does not get the right push when I logout of a gnome-shell
session (this is all in fc17).
So, who is missing a message? (or whatever) Pam? Gnome-shell?
Systemd? Another obscure little piece of the puzzle that I can't yet
see?
Hmm, so if the PAM sessoin end hooks are not called then this would be a
bug in gdm. Did you check auth.log whether the session logout hooks log
anything there?
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?
