libcups asks for password when its not needed

[glance]

Binary package hint: cups

We have a cups-setup that allows remote printing when authenticated, and accepts local printing from a "trusted" network without authentication.

The Location bock looks like this:

<Location />
  # allow either authorized of remote users
  Satisfy any
  Order deny,allow
  # remote access needs to be authed.
  AuthType Default
  Require valid-user
  # local access is always allowed.
  Allow from 127.0.0.1
  Allow from a.b.c.d/255.255.255.0
  Deny from all
</Location>

When using cmd-line utils, like lpr, lpq, lprm and so on, it doesn't ask for a password, but when using GUI-programs that uses libcups they see the CUPS_PRINTER_AUTHENTICATED-flag on the printer and asks for username/password without needing to.

Reported upstream: http://www.cups.org/str.php?L3862

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Ryan Lovett (ryan-spacecoaster)]

This affects 12.04.

cupsd running on the client enumerates the Type field with CUPS_PRINTER_AUTHENTICATED (0x400000).

CUPS no longer has a public bug tracker. I found the following (regarding old CUPS bug #3862) at http://comments.gmane.org/gmane.comp.printing.cups.devel/4814:

  [STR Closed w/o Resolution]

  This is being done by the GUI apps, not by CUPS...

Ryan, which GUI tools are you using?
