This involves some smaller steps:\n<ul>\n<li>CUPS needs an <a href=\"http:\/\/cups.org\/str.php?L2750\">auth-info-required bug<\/a> fixed, so that when a print job requires authentication details from the user, it is possible to find out what sort of details are needed.<\/li>\n<li>The pycups Python bindings for libcups need to have an authenticateJob() function added.<\/li>\n<li>The system-config-printer applet needs to display a window for the user to fill in credentials when a job requires it, and use authenticateJob() to let it continue processing.<\/li>\n<li><small>UPDATED:<\/small> Oh, and the samba CUPS backend needs to use the auth-info mechanism when the URI does not contain the information.<\/li>\n<\/ul>\n<\/li>\n<li>The current SMB browsing code in system-config-printer needs to be replaced with something based on libsmbclient.
