Comment 20 for bug 653132

The fix in python-cups only prevents an infinite loop of the login/password pop-up, so that it does not appear again when clicking "Cancel". So you are at least able to close the add-printer wizard. But note that you are still not able to actually log in using user name and password of an authorized user (user in "lpadmin" group, first user set up). This requires also the update of system-config-printer.

With both updates all works correctly:

- No prompt 'Password for "root" at localhost', No pre-filled "root" in user name field
- Canceling the login/password dialog closes it without it popping up again.
- Entering nothing, invalid credentials, wrong password, or unauthorized user and then clicking OK, gives "Not authorized" error pop-up and afterwards the login/password dialog appears again.
- Entering correct credentials allows the current administrative operation and all further administrative operations until closing system-config-printer, without any further login/password dialog.

Please test also this as soon as the update for system-config-printer gets approved.
