[Help-gnu-radius] User-Password doesn't seem to be computed

[address@hidden]

Hello,
I am trying to use gnu-radius but my first tests fail as I cannot check if 
gnu-radius properly decode an incoming authentication request.
I am using a radius client to send an auth request to gnu-radius.
I have specified the shared secret in the 'clients' file.
The User-Password is not what has been sent and I have difficulties to find 
out what is wrong.

how can i check what shared secret is really used ?

I have tried to play with the logging options in order to check what 
User-Password is obtained but I ddin't succeed (they are very complex... 
certainly very powerful but complex).
As a workaround I used exec_program-wait with %C{User-Password} to be able 
to log this and I always see a crypted password.

There is also an option allowing to get a log of each incoming packet. Here 
is what I get :

Thu Apr  8 11:46:02 2004
        User-Name = 2123193906
        Acct-Session-Id = adeolis-1965
        NAS-Identifier = adeolis-1
        NAS-IP-Address = 192.168.2.10
        Timestamp = 1081417562
        Request-Authenticator = None


The User-Password is missing and there is also a "Request-Authenticator = 
None" message which I don't understand. The request authenticator is a 16 
random number for Access-Request and is present in my packet...


Does anyone know how i could perform this first level checking ?
Many thank's.
