It's at least different than your definition. Irregardless, my point
still stands - Digest without message body authentication is still
susceptable to attack and can't be considered "secure" by any stretch
of the imagination. *More* secure than Basic, but definitely not

Apache is just one example, and I'm sure there are a lot of servers
out there that have similar limitations. The point is, MOST IPP
implementations will rely on an existing server (one that the vendor
has already implemented or licensed), so we have to be careful about
requiring too much too soon (otherwise IPP will not be accepted by
the industry at-large and we'll have yet another useless "standard"
that no one uses!)

Unless absolutely required by the IETF, I'd be very much against any
such wording. This whole discussion should be proof enough that one
person's "secure" solution can be seen as inadequate or unsecure by
Let the implementers decide what options are necessary and
appropriate, and if stronger language is requested by the IETF add it
as a recommendation and not a requirement.
