This implements a method for configuring authenticator reference values for Keycloak authenticator executions and a protocol mapper for populating the AMR claim in the resulting OIDC tokens.
This implementation adds a default configuration item to each authenticator execution, allowing administrators to configure an authenticator reference value. Upon successful completion of an authenticator during an authentication flow, Keycloak tracks the execution ID in a user session note.
The protocol mapper pulls the list of completed authenticators from the user session notes and loads the associated configurations for each authenticator execution. It then captures the list of authenticator references from these configs and sets it in the AMR claim of the resulting tokens.
