# The policy below is added by SUSE during build of our cups package.
# The policy 'allowallforanybody' is totally open and insecure and therefore
# it can only be used within an internal network where only trused users exist
# and where the cupsd is not accessible at all from any external host, see
# http://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings
# Have in mind that any user who is allowed to do printer admin tasks
# can change the print queues as he likes - e.g. send copies of confidental
# print jobs from an internal network to any external destination, see
# http://en.opensuse.org/SDB:CUPS_in_a_Nutshell
# For documentation regarding 'Managing Operation Policies' see
# http://www.cups.org/documentation.php/doc-1.7/policies.html
<Policy allowallforanybody>
  # Allow anybody to access job's private values:
  JobPrivateAccess all
  # Make none of the job values to be private:
  JobPrivateValues none
  # Allow anybody to access subscription's private values:
  SubscriptionPrivateAccess all
  # Make none of the subscription values to be private:
  SubscriptionPrivateValues none
  # Allow anybody to do all IPP operations:
  # Currently the IPP operations Validate-Job Cancel-Jobs Cancel-My-Jobs Close-Job CUPS-Get-Document
  # must be additionally exlicitly specified because those IPP operations are not included
  # in the "All" wildcard value - otherwise cupsd prints error messages of the form
  # "No limit for Validate-Job defined in policy allowallforanybody and no suitable template found."

  # Since CUPS > 1.5.4 the "All" wildcard value must be specified separately,
  # otherwise clients like "lpstat -p" just hang up,
