Uh, pardon this dumb question, but you *did* remember to set
it when you authenticated your user, correct? Something like:

request.getRemoteAddr() );

Or, if you prefer a host name instead of an IP address, use


Maybe you thought that the Authenticator.login() method would
do that for you, but it doesn't.

Now, if on the other hand, you are setting it, you will have to give us
a bit more details...ideally a short code snippet that shows us what
you are doing.
