I am trying to write some functionality of SMB server.
From my code, I am sending a AUTH_CRAP message to winbindd daemon.
That is successful and sending back the response.
In this response, I have the user session key.
Now, I have to use this to find the "Signing Session Key".
I am doing hmac_md5 twice on this "User Session Key".
But, the result that I am getting is wrong.
So, can somebody tell me, the correct way to calculate "Signing
Session Key" from "User Session Key" given out by winbindd?
