Hi all, Here is a small piece of log from the radius auth module that i wrote. Just by curiosity, i patched mod_sofia to handle incoming registration requests with radius.I used freeradius-client library like the mod_radius_cdr module.Almost all the client configuration is in radiusclient.conf.xml. I hope i am not duplicating someone else's work.I am planning to release it after adding a few more features..If someone has a better idea, some thoughts about a cool feature or anything, i will be happy to hear that..
