Looks like a Windows domain user. That site likely uses the NTLM authentication scheme. See the mailing list archives for more examples on the nastiness of that protocol. Interestingly enough, Microsoft recommends NOT to use it over the Internet (and has been doing so for the last 10 years). You should write the webmaster of that site and ask him to move to a standard authentication scheme such as Digest or Basic over HTTPS. Kinkie
