Comment 32 for bug 209520

Confirmed on Hardy Heron 8.04, with additional information:

If you attempt to connect to an authenticated SMB share, you get a blank window in Nautilus.

BUT:

If you append to the server name string, one of the available shared directories, you're asked if you want to allow access to the keyring. If you allow access, the directory mounts!

e.g.:

Places/Connect to Server/
Select SMB
Enter Server name

Nautilus window comes up, no subdirectories shown

append the name of one subdirectory to the "smb://servername/" in the location bar

"Allow access to keyring" box pops up, and, when "Allow" is clicked,

Contents of the specified shared directory appear, and it is shown as mounted in the "Tree" pane on the left.
