Cancel Cups jobs from another machine

[Deniz Yavuz]

Sers Cups Forum,

i have a problem with my current cups server and my two cups clients.

I configured the cups server with not many problems, both clients can connect to the server, and if they are going to the administration site, the authentification comes immediatly, well done.

Now i've got the question/problem:
Sometimes, if my printer is out of paper, or there is something to do on the hardware (don't know the word in english, sry) and there are print jobs, somebody must be cancel these jobs. I wanted that so, that the clients cancel's there jobs themselves. ok, on client B it's not the problem, but on client C came's every time a request about authentification and i don't know why.

here my cupsd.conf
