When attempting to mount an NFS system with outdated metadata Dolphin will return an error 'Authorization required'. This 'Authorization required' is misleading as the actual problem is not permission related and the proper solution/fix is to run `exportfs` on the server. STEPS TO REPRODUCE 1. Run an NFS system on a host machine, allowing clients to mount 2. Mount the remote NFS folder on the client machine 3. Unmount the system on the host machine to force a stale file handle situation 4. Unmount and remount the folder on the client WHAT HAPPENED Dolphin says 'Authorization required to enter this folder' WHAT EXPECTED Dolphin returns the proper issue
