Smith,
Sorry, my confusion continues. Your new Authorization example may be valid, but it seems odd to me that someone would have an account in a printer but not have authority to print at all. Conditional authority, restricting use to certain times or restricting color, or quantity, etc. would be more realistic, but that is at the IPP level and does not appear to be addressed in this specification.
The title is Authentication Methods, and although I may have missed it, I do not think that it does much with authorization (at least not by the printer), which would occur after successful Authentication. Perhaps the Authorization use case should be put in the out of scope section?
Thanks, Bill W.

Thanks for the feedback Chris! I also received this feedback from Canon's Rick Yardumian (CC'ed). In my LCRC draft, I've resolved this issue by rewriting 3.3.2 to more meaningfully describe an authorization failure.
Here's the rewrite. Any objections or suggestions?
Harry is also visiting Andy's office and wants to print from his laptop. He uses his laptop to discover available printers, and selects one listed. The printer is configured to limit access to only authorized users.
The printer challenges the laptop for authentication, and the laptop presents an authentication dialog to Harry. Harry has an account, and enters the account's username and password. The printer accepts these credentials, but that account is not authorized to access that printer. Harry's laptop shows a notification dialog expressing this to Harry. Harry clicks “OK” and looks for a pencil.

Just curious, but section 3.3 Exceptions of this document has sections 3.3.1 and 3.3.2 which are pretty much exact duplicates of each other, exception being Lisa vs. Harry. Was this intentional?
Thanks,
