Hi, I am new to this AAA freeradius area, I need to configure the AAA radius server for following mentioned attributes according to the message, Access-req, Access-Accept, and Access-Challenge, and Access-Reject (pls see below). Also, I looked at the configuration files at radius server like clients.conf, users, radiusd.conf - I am not sure where this attributes to configure. Could any body help me getting started with this that would be highly appreciated. Also, please comment on the VSA attribute below - I am tryign to understand on section 5.26, RFC 2865 - but not sure where to start. Your help would be highly appreciated.
