I am using OpenAm 13, testing a realam with oauth and openid already configured.
When I do a POST with grant_type=password, scope=openid and the credentials (body) of a demo user, I get an id_token.
But when I do a POST with grant_type=client_credentials, scope=openid and the credentials (basic) of a client, I get:
“error_description”: “User must be authenticated to issue ID tokens.”
If I ask for an other scope I get it successfully.
Why is client credentials not working with openid?
