Hi Paul and Carl,

Apropos - in the SNMPv3 WG they are now moving
forward an alternate standard security model
(instead of RFC 2574) - Kerberos 5.

Cheers,
- Ira McDonald

PS - If your HTTP layer is doing Kerberos or other
magic that provides strong security and integrity
then sending a meaningful user name in the 
"requesting-user-name" attribute becomes suitable
in some applications (as opposed to looking for
the ephemeral 'most authenticated user name').

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.
