> The Get Filesystem Properties operation requires Read permission to the
> Filesystem. Read permission to the Filesystem can only be granted thru RBAC,
> Shared Key, or SAS. This prevents giving low privilege users access to
> specific files or directories within the filesystem. An administrator should
> be able to set an ACL on a file granting read permission to a user, without
> giving them read permission to the entire Filesystem.
> Fortunately there is another way to determine if HNS is enabled. The Get
> Path Access Control (getAclStatus) operation only requires traversal access,
> and for the root folder / all authenticated users have traversal access.
