Comment 55 for bug 283811

I had all the symptoms described when I set up a printer
on Ubuntu 9.04 using the normal
Administration->Printing->
New->Select Device-> Network Printer->
Windows Printer via SAMBA->Browsing for the smb shared printer
and Having "Prompt user if authentication is required" checked.

The same setup but having "Set authentication details now" checked
with Username & Password correctly entered for the smb share
works flawlessly.

There is no line in printers.conf stating
AuthInfoRequired username,password
