Use Google as OAuth 2.0 server

Google is not supported

The main reason is because it does not issue JWT access tokens but opaque access tokens. To support opaque access tokens, RabbitMQ would have to issue an external HTTP request to convert the opaque access token into a JWT access token.

Under the /conf/google folder you can find the configuration used to connect the RabbitMQ management UI with Google OAuth 2.0 endpoints. With this configuration, you can get to a point where the user is authenticated by Google, and eventually you get the error message in the RabbitMQ Management UI "Not Authorized".

The reason is because RabbitMQ cannot validate the access token because it is invalid.
