      Description

      The documentation states:
      New in 3.2: Enables a ZooKeeper ensemble administrator to access the znode hierarchy as a "super" user. In particular no ACL checking occurs for a user authenticated as super.

      However, if a super user does something like:
      zk.setACL("/", Ids.READ_ACL_UNSAFE, -1);

      the super user is now bound by read-only ACL. This is not what I would expect to see given the documentation. It can be fixed by moving the chec for the "super" authId in PrepRequestProcessor.checkACL to before the for(ACL a : acl) loop.
