This defines the shared secret that is used to decrypt RADIUS
messages that are received from 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.
EncryptedSecret is currently experimental and
will be documented later.
# This better agree with the client at
