I'm happy to review suggested text.

I think you'd need to:

1) Explain how I figure out which entity I'm using for my RADIUS server

2) Explain how I validate the RADIUS server I'm talking to

3) Explain how the RADIUS server I'm talking to validates me.

Consider this especially in a case where you're retrieving metadata
dynamically rather than just having all the metadata in the world.
