Accessing the root folder of a file mount is not possible for non-admins
The change "[!!!][TASK] Driver API has too many crosscutting concerns" f83eddd5027b74d7f4d28a845521bff3b2dd603d breaks filemounts for non-admins (or changes the configuration needed?). After this change, a non-admin cannot access the root folder of a filemount. Sub-folders of a filemount work.
The error message is: "You are not allowed to access the given folder."
