You send a packet that does not contain any MS-CHAP attributes. Because of 
that, the server is not doing MS-CHAP:

>   modcall[authorize]: module "mschap" returns noop for request 0

As this line tells you.

Send a MS-CHAP request, and look what happens then.

Hi ,

Now i send a mschap request (EAP/PEAP with WindowsXP) and that is the output of my radiusd:

rad_recv: Access-Request packet from host 10.187.0.15:1645, id=229, length=137

Finished request 0
Going to the next request
 

Again the   
modcall[authorize]: module "mschap" returns noop for request 0
You said, this mean i do not send a mschap request.

What else can i do ?

Many thanks in Advance
Robert
