Bug Description
We have a CUPS server configured to allow printing over IPP w/ TLS. Printing requires the user to authenticate using basic authentication.
When printers are set up in Ubuntu 11.04 and lower, the user is prompted to enter their username and password when they attempt to print.
However, on upgrading to 11.04 (or doing a fresh install), the user no longer gets a prompt and the job does not go through.
The error logs show some TLS errors, however printing proceeds normally if authentication is removed.
Here is a relevant chunk from the error_log on the server (running 1.4.3, but this was tested and duplicated on an ubuntu 11.10 server):

Are you using the Unity or the GNOME shell (classic) desktop? If you are using the latter, can you switch to Unity and see whether printing works correctky there for you?
Can you check whether a system- config- printer- applet process is running on your system?
