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 ?
