RPBroker

This authenticator delegates the authentication to a trusted (internal or external) OIDC OP. It authenticates by sending an authentication request to that OP and then validating the id_token. This authenticator currently only supports Authorization Code Flow. 

Configuring the authenticator

Before enabling the authenticator ensure that phenix-oidc-discovery module is enabled and that the right OIDC OP has been configured for discovery. This is important and required even if the target OP is internal.

Requirements

The pipe executed MUST respond with one item. The phenix-oidc-discovery module must be enabled so that the OIDC OP's endpoints can be saved and used for the authentication. This is required even if the target OP is internal.
