pam -- how to handle reply attributes

Hi,I wrote my PAM module (to authenticate a user against Sun AM) for freeRadius and that part is working fine. Now, the PAM module will receive few response attributes from the authenticating application for each user, for whom the authentication is success.How to receive this kind of application specific attributes and how to insert them in Radius-Accept packet? This is an urgent requirement for me.Appreciating your helpThanks,Sri.
