OK.. so first time I am working with free radius (or any kind of radius server) .. so please bear with me. I have a ubuntu based system on which I have installed freeradius 2.1.8 I have created my own new module called grid which is intended to only provide an authentication function I have the code compiled and the .so installed to the lib directory I have modified the radiusd.conf file to include the new module I have updated the sites-available/default file to include the new authentication type. In fact since all i am interested in is authentication, i have removed entries from all the other sections. So my default file looks like ========================= authorize {} authenticate { Auth-Type GRID { grid } } preacct {} accounting {} session {} post-auth {} pre-proxy {} post-proxy {} =========================== I start up radius in debug mode and send in the following test request 'radtest abc 123 127.0.0.1 10 testing123' and I get the No Auth -Type specified error.. Attached below is the output from radius. Could somebody please tell me what I am doing wrong ?
