radclient from xtradius always fail?

[Stephane Bortzmeyer]

I configured a FreeRadius server and tested it with FreeRadius'
radclient. It works.

However, when I try the radclient from xtradius, I always get an
access denied. I think that FreeRadius is supposed to work with other
Radius implementations :-) so there is something strange.

With FreeRadius's radclient:

% echo "User-Name = bortzmeyer\nUser-Password = theuserpassword" | radclient jezabel auth mysharedsecret
Received response ID 181, code 2, length = 44
        Service-Type = Framed-User
        Framed-Protocol = PPP
...

With xtradius' radclient, same client machine:

% echo "User-Name = bortzmeyer\nUser-Password = theuserpassword" | radclient jezabel auth mysharedsecret
Sending request to server jezabel, port 1812.
Warning: Received invalid reply digest from server
radrecv: Packet from host 10.1.82.2 code=3, id=13, length=20
Access denied.

And, on the FreeRadius server, when it fails:

rad_recv: Access-Request packet from host 10.1.82.1:32774, id=13, length=50
