Comment 19 for bug 445333

I have the same problem. I'm using Karma (9.10) and I'm printing to a Samba shared printer. I open the printer configuration dialog (system-config-printer), double-click on my printer, and click on "Change..." next to the device URI. After waiting some time while it's searching for printers (why is this necessary, by the way?), I select "Set authentication details now", enter my username and password and click on the "Apply" button. This has no effect whatsoever. When I reopen the dialog by clicking on "Change..." again, it has forgotten my username and password.

Indeed when I try printing from Document Viewer, it keeps asking me for my username and password every time.
