Client Id and Secret support?

[jonesir]

Hi I am using the approach with Client Id and Secret and was able to retrieve access_token with username and password, however, when passing this to the backend, I got:
WARN [Keycloak] Cannot validate access token: Error: Grant validation failed. Reason: failed to load public key to verify token. Reason: Expected "jwk" to be an Object

Which means the kid in this access_token does not exist in the /certs response.

Any plan to support the Client Id and Secret way for a client or am I missing some settings or so? I was not able to fine a way sofar(as a newbie to keycloak) to add the mentioned kid into the list of kids returned by /certs.

Thanks in advance.
