Comment 1 for bug 1264139

I get the same error and behavior. on top of that. When i close the configuration dialog and re-open it, the username and password fields are blank.

I enabled debugging for CIFS, and dmesg shows a lot of output, but it only seems to ever try logging in as "Anonymous" or "Guest". Obviously that won't work.

I connect to a folder that doesn't require authentication, then everything works as expected.
