Re: [keycloak-dev] token exchange
'aud' is broken:
https://issues.jboss.org/browse/KEYCLOAK-1201
Big question is how do you control what the list of "clients" in the aud
should be? Manually? Based on scope (what about full scope and loads of
clients, what about when there are no client roles)?

When Client A gets token to invoke Service B, how the "aud" claim in the
token looks like for you ? Is it referencing Service B ?
Asking because I noticed that our access tokens are being issued using the
authenticated client in "aud" claim where it should contain (or in addition
to other audiences) the target service. A typical scenario for bearer token
authentication. Also, our BearerTokenRequestAuthenticator does not seem
to validate audience.
Considering the flow you described, Client A would need a token with
Service B as a valid audience in order to be able to start the flow.
