[Mailman-Developers] Reusing mailman login/pass or cookie ?

I've developped a few php scripts for the users of some of my lists, what I need is to have only users effectively subscribed and authenticated to the lists to be able to use the scripts.

I also need to know what is the user's login in the php scripts.

Is there a way to do that , either by reproducing the mailman auth process in php or by reusing the mailman cookie ?

Anyone has already done that or knows of a way to do that ?

thanks
