Set allowed users makes printer invisible

[John A. Murdie]

Here's an odd problem - which I haven't perhaps characterised enough to report as a bug. When one sets an 'Allow these users to print' list (e.g. "john at SITE.AC.UK,lucy at SITE.AC.UK") for a printer in CUPS 1.3.7 operated with 'AuthType Negotiate', with patches for bugs 2748, 2749, 2782 and 2783, the printer is lost from the web list of printers. It is reported as non-existent for printing, though it is recorded in printers.conf with the above users each given an "AllowUser" line.

To fix the problem, I edited out the permission lines and restarted cupsd. The problem is reproduceable. I have the cupsd with LogLevel set to Info (it is our production server) and haven't yet tried this somewhere I can reasonably set debug/debug2, and there is no apparently applicable error message in error_log.

Has anyone else seen this?
