Know the username of a user trying to logged

Question

I've a debian system, when a user try to login, a pam module exec a bash script as root. I need this script to know who is trying to login.

But the user isn't already connected so basic command as users/w/who ... doesn't work here.

So is there a possibility to retrieve the username of a user trying to get logged ?

Thank you. Cyrbil

You can also use /etc/profile or /etc/bashrc to grab the user logging in, I typically have a small script that gets executed via /etc/bashrc that gives me details about the user (who it is, connecting from what IP address etc).
