This defines the shared secret that is used with messages exchanged with this client. You must define a shared secret for each Client, and it must match the secret configured into the client RADIUS software. EncryptedSecret is in encrypted format and is preferred over Secret. See Section 3.14.1. Secret for more about RADIUS shared secrets.

EncryptedSecret is currently experimental and will be documented later.
