Description Bryan Mason 2021-09-22 18:58:56 UTC

Description of problem:

  If an administrator wants to allow unfettered access to allow
  unauthenticated users to perform administration functions, they can do
  this by removing Require user entries from cupsd.conf.  This works for
  everything but the "Move Job" operation in the "Jobs" page. Because
  cgiMoveJob() returns 401 when REMOTE_USER is not supplied, it is
  impossible to move the job using the Web UI.

Version-Release number of selected component (if applicable):

  cups-2.2.6-38.el8

How reproducible:

  100%

Steps to Reproduce:

 1. Remove all "Require user" entries in cupsd.conf
 
 2. Submit a print job "lp -d test -H Hold /etc/fstab"
 
 3. Go to https://localhost/jobs and press the "Move Job" button
    to move the print job.

Actual results:

  Unauthorized

  Enter your username and password or the root username and password to
  access this page. If you are using Kerberos authentication, make sure
  you have a valid Kerberos ticket.

Expected results:

  The unauthenticated user should be able to move the job.

  I'll work up a test package shortly.
