Non-administrator users cannot view contents within a dokan filesystem.

```
Non-administrator users can mount an iphone with iphile, which depends on 
dokan, but they cannot view the dokan filesystem's contents. The related 
privilege seems required to export to a user group, in order to allow 
Non-administrator users to join in.
