Hmm, so there are multiple ways to achieve this, but it really depends
on what you are trying to do here. May I ask what kind of script you
want to run for a user logging in? Also do you want this to run
prviliged or unprivieleged?

One possible way is probably to hook this into the PAM session
setup/shutdown so that you can catch all types of logins with this. If
you need to run a script rather than write a PAM script a quick google
search reveals that pam-hooks might be the way to go?

Anyway, I can make a better recommendation with a few hints on the
intended usecases
