Hi,

I've got a query regarding a use case:

1. Client with self-issued JWT bearer assertion grant
2. No explicit client auth, i.e. authentication is done via the
presented JWT grant

What value should then the *token_endpoint_auth_method* reg parameter
for the client have?

"none" is apparently reserved for public clients:
http://tools.ietf.org/html/rfc7591#section-2

Empty value perhaps?

Thanks,

Vladimir
