Hi all,

I have been pondering about whether we are trying to make life a little too
difficult for ourselves when we look for a solution to this issue. Here is a
totally different proposal.

Considering that:

- ALL IPP/1.0 and 1.1 clients AND printers MUST support Basic and Digest
Authentication (see the IPP Encoding & Transport drafts).
- the Basic Authentication is being deprecated in the new HTTP/1.1 Draft
Standard, and might disappear from future HTTP products.

Why don't we mandate in IPP/1.1 that IPP printers ALWAYS send a challenge
for Digest Authentication?
This would make it unnecessary for the IPP client to ever need to request a
challenge.

A possible drawback might be that the user may have to fill in extra
security information for each print request, but maybe this can be cached in
a user profile. I expect that people who have designed real clients have
already solved that problem.

Comments?
