802.1x post Authentication and Authorization user processing

Hi, In my system freeradius 1.1.15 is configured (and working) for performing authentication and authorization of wireless and wired clients through 802.1x. But I need to perform an additional task and I wanted to know what would be the best approach to do it: - After the authentication and authorization process succeeds I need to pass the authenticated/authorized username and mac address to my firewall system in order to "authenticate" the client in my firewall. If you people have any ideas of one possible good solution, please let me know. Thanks in advance nelson
