Description

The existing permission checks are skipped under the following conditions:

• dfs.permissions.enabled is set to false. (There are several exceptions stated in the documentation.)
• The user is the super-user.
• The user is a member of the super-user group.
  Add tests verifying that ACL enforcement is also skipped for all of these cases.
