windows 11 IPP class driver basic auth support

Question

Does anyone know if windows 11 built in IPP class driver supports basic auth at all?

I'm trying to add an IPP printer shared from a Linux cups, the printer installs on the system but nothing can be printed - I'm looking at the communication with wireshark and looking in the cups logs - you can see that windows sends Validate-Job, Create-Job requests - cups in response sends a 401 basic auth challenge - I would expect windows to then show a window where I can enter a username/password, but nothing like that happens. The submitted printout sits in the queue, windows keeps trying to send it to cups but never succeeds. I tried to find some username/password settings in the IPP port assigned to this printer - but the only thing that can be changed there is the ip address.... There is no option to set username/password? After all, this is one of the most important feature that IPP gives?

Answer 1

The built-in IPP class driver in Windows driver has limited support for authentication, and unfortunately, it does not natively support prompting for credentials or basic authentication.

To resolve this issue consider installing a third-party IPP driver, such as the one provided by CUPS itself or another manufacturer.
