NTLM authentication with GWT but getThreadRequest() is null

Question

Hello,

I am trying to get NTLM authentication to work with GWT. Unfortunately the getThreadRequest doesn't seem to be returning anything useful.

I am doing this: http://www.jroller.com/paul/entry/using_ntlm_windows_login_and

I have a suspicion that it won't work if I am testing locally? Will IE still send NTLM headers if I am testing locally?
