Step 4: Set Advanced Folder Permissions

There is one additional trick that you must use to complete the shared folder permissions. When Fedora Linux creates a user account, it assigns each user to a unique group (which happens to be the same as the username). Unfortunately, this causes problems in a shared folder environment.

Even though your users are all members of the same group, their primary Linux group is still their unique group name. When a user creates a new file in the shared folder, it belongs to the user’s primary group, not your newly created group.
