RE: exec external script on successful proxy authentication

Is there a way to execute a script with the original request attributes at the time of successul receipt of authentication reply from a home server when FreeRADIUS is used as a proxy? We require to execute an auxilary action on successful authentication, but currently have only found ways to do this at the time of request.

Have you looked at the post-proxy and/or post-auth stages in radiusd.conf? You could call a perl script during those stages. The request and reply attributes are available in hashes within the perl script.
