Comment 7 for bug 735297

OK I now see what is happening. I commented out the "AuthInfoRequired" line but I still get the problem. The issue is that the follow me line still has the old password and it will not update it automatically after prompted even when I click the "Remember Password" option.

That explains why it works when deleted. All entries are erased and recreated when the new printer is created. But for whatever reason it cannot update the password to an existing printer.

I think this is a serious bug that could affect the use of Ubuntu in enterprise environments.
