Hi,

I am working on Authentication module in NSIS protocol suite (http://user.informatik.uni-goettingen.de/~nsis/).
The scenario is as follows:
User A-------- NSIS server---------Radius server

User A sends the NSIS request with its keyed hash (generated using User A's key) appended to it to the NSIS server. Now the NSIS server needs to authenticate that request with a Radius server.

Is there a way to do this i.e. how to generate a AAA message with the information available i.e. a string, its keyed hash and User A's id ? Assuming that the Radius server has keys of all legitimate users.

Regards,
Prateek
