hey all, 

I am trying to setup a test script using radauth, but when I do it I get
a return of :

radtest : error: sendto: Invalid argument
Authentication failed. Reply code 0


and the username and password I use are 100% correct.

the command I use is :
/usr/local/sbin/radauth user password

GNU radius 1.5 is the version I use.
Strange thing is on our version 1.1 it is working with the same command.

Anyone who has any idea's?
