Ship it!




Looks good to me. Ideally I'd like Dawit to take a look, but if he doesn't, feel free to push.
Especially since the release is tomorrow, and I guess you'd like this in ;)

> Some IIS servers seem to be configured to reject NTLMv1 authentication by refusing to reply to a NTLM stage 1 if the NTLMv2 flag is not set. If such a thing happens try to send another stage 1 message with the NTLMv2 flag set and if the server accepts this continue with NTLMv2.
