# pam-hooks - PAM module to execute login/logout actions

Yesterday I've finally [[published|hacking/software/pam-hooks]] a PAM module I
wrote a while ago to implement an apparently trivial need which I haven't found
implemented elsewhere.  What I wanted to do was simply to be able to execute
hook scripts upon an user is entering or leaving a PAM session. Actually, my use
case is to clean the home directory of a user upon its GDM logout (and to be
sure also just after he logs in) as such a user is a "dummy" one, reused by
several people in a stripped down kiosk-like environment.

When I did my googling about this I was able to find only Enrique Ocaña's [PAM
preprofile](http://community.igalia.com/twiki/bin/view/Corunix/InstallPamPreprofile_1_0)
which can force script execution at authentication time, but nothing for the
logout.  So I wrote my own toy module, generalizing a bit the API so that
invoked scripts are informed about whether a login or logout is in process.

The result is [[hacking/software/pam-hooks]]. It is not in Debian since I do not
know how many people can be interested in such a thing; in case you are just let
me know.

Dear lazyweb, comments, code auditing, and pointers to similar stuff I've
overlooked are really welcome.
