    Without a standard, I guess we can't do interop testing, anyway, though
    there is a proposal at

    http://hex.tamu.edu/drafts/draft-smith-http-third-party-authentication-00.txt

    Is there a "de facto" standard documented somewhere?

    Correct - there is no standard for Kerberizing HTTP. MS have added a new
    authentiation scheme that triggers a GSSAPI/SPNEGO interaction. This does
    either
    Kerberos or NTLM depending on whether or not the client is capable of
    Kerberos.
    Throw in a bit of Base64 encoding and you're done.

    Hmm... I wasn't aware of a standard for Kerberos HTTP authentication,
    either, although there has been some recent discussion on the http-wg list
    about "ticket based authentication" (see
    http://www.ics.uci.edu/pub/ietf/http/hypermail/2000/0165.html). How does
    W2K implement this?

    IE5 on Windows 2000, and hence the MS IPP client on Windows 2000, does
    Kerberos
    authentication. IPP just rides on the back of whatever HTTP authentication
    happens to be available.

    Peter-

    I see Kerberos listed under Authentication and Security. I didn't know IPP
    had Kerberos authentication. I'm interested in finding out more about
    this. Kerberos has a lot of advantages in a distributed environment, e.g.,
    single sign on and centralized administration.
