I have a SuSE 10.0 client, without a cups server running and a CUPS
server, Version 1.2.2, compiled from source.

I´m accessing the CUPS server on the https port, but Port 631 shows the
same problems.

Using konqueror for accessing the server via a web interface and trying
to cancel a job results in a popup for authentication.
Using the shell command results in a prompt for authentication.
In both cases, the jobs can be cancelled if the right credentials are given.

Using kprinter results in a access denied popup, no matter which
username and password I use in the System Options.

The server section for canceling jobs is like this:

     77   # Only the owner or an administrator can cancel or
authenticate a job...
     78   <Limit Cancel-Job CUPS-Authenticate-Job>
     79     AuthType Basic
     80     Require user @OWNER @SYSTEM
     81     Order deny,allow
     82   </Limit>

The error log shows the following: (I put a larger part in the mail)
