[jcifs] getting the password after successful NTLM HTTP Filter

Thanks for the response, it was what I thought.
I am therefore going to have the web app generate a temporary, pseudo
random, timestamped password, store it and pass it to the application.
The application will then check if it was stored (and within a timeout
period) and delete it (to avoid repeat attacks).
Does this make sense to you? Is there an easier way that I'm missing?
Where do you think would be the best place to store the temporary

The hashes are not really available to JCifs, just the responses
(formulated from the hash and the challenge sent by the server). In
the Windows world the hash is a password-equivalent. So the server
sends a challenge which the client combines with the password hash to
get the response; the server does the same calculation to verify they
know the password.
Unfortunately the response will be different for each challenge, so
there's not really a way to store the hash and use that in your app.
