[Users] radius authentication

Ciao!

I'm trying to authenticate using Radius. I've installed radiusclient-ng 0.5.2 i've configured radiusclient.conf with the IP address of the radius server. I've configured SER with: ... modparam("auth_radius", "radius_config", "/etc/radiusclient-ng/radiusclient.conf") ... if (method=="REGISTER") { if (!radius_www_authorize("example.it")) { www_challenge("example.it", "0"); exit; } save("location"); }

but it doesn't work: there seem to be a problem in the client because there is no IP Packet that goes out directed to the radius server... in the log of SER i have no errors...

thank you for any help, Stefano
