Hi all,


Sorry, but I'm confused about HMAC-MD5 method.

I'm working on Radius Proxy Implementation.



The scenario is the following


RADIUS Client -> Radius Proxy -> Radius Server.



Radius Client sends a Radius Packet towards Radius Proxy
(Message-Authenticator not used).


Radius Proxy sends the Radius Packet towards Radius Server using
HMAC-MD5 method. How to configure RADIUS Proxy? Should I add
MD5-Password Attribute? MD5-Password is identical to Shared Secret
between Radius Proxy and Radius Server? 


Thanks in advance
