I use Mozilla to NTLM authentication, I found that when mozilla need to send
type-3 message, it sent a wrong NTLM challenger. The webserver asked for
Domain's NTLM challenger, the browser sent my box's NTLM challenger.

Reproducible: Sometimes

Steps to Reproduce:
1. Login a company's domain.
2. install ethereal. Monitor your host's network traffic.
3. access a webserver which require NTLM authentication. You can compare the
traffic with IE's result. I found that the type-1-message is different as well.
The type-3-message is picked from local box's NTLM challenger rather than the
domain's NTLM challenger ( as required by webserver).

Expected Results:  
When webserver ask for NTLM challenger for a domain, the browser should send
request to Domain COntroller to get the NTLM challenger. Then send this
challenger to webserver in type-3-message.

hmm... mozilla is simply using microsoft APIs to generate the NTLM authorization
headers.  reporter: can you describe further the problem?
