> DigestAuthenticator currently generates nonces as a hash of the client's remote ip, the current time at generation time, and an internal server key.  With high concurrent load in a scenario where many clients show a single ip (such as behind a loadbalancer/proxy), then it is very easy for DigestAuthenticator to give out duplicate nonces when they are generated at the same time.
> This then leads to authentication failues as counts for the duplicate nonces get out of whack.
