About the authentication problem, there was a problem introduced
with CUPS-1.1.20 that changes its behavior. Previously, CUPS used to
cache the password given by the user, such that it wasn't requested
upon subsequent actions. This is not the case anymore. This resulted
in the KDE print manager in the user being requested the admin pwd
4 times when creating a print queue (because it consists of 4 different
operations).
Try to enter admin user/pwd 4 or 5 times, then it should finally
succeed. If not, please tell me.

Michael.
