I believe that code is broken, Mohammad. There were assumptions that use to hold true that didn't make the transition from a redirect filter to a handler which happened quite a while back. I also think that it is broken that we need admin and knoxsso topologies. That needs to be triaged and fixed.
In the meantime, you can add an authorization provider config that denies access to everyone if that is a problem. Feel free to file JIRAs.
