Authentication to CUPS from kprinter

I did this, but after it failed, I tried to set a password by hand...

It looks like this now, but with no other result...
The error messages seems to be the same:

To me it looks like that the credentials are not delivered to CUPS or
not in the right way. Could this be tested? (Maybe without using ethereal)

What I do not understand, what would cause kprinter to show an
authentication popup, like the one for konqueror, and is kprinter able
to do so?
