I want to integrate IRIS with Keycloak OAuth2 provider to use delegated authentication everywhere and to secure everything - sys*/Portal applications, REST services, FHIR server and so on. If an unathenticated user tries to access any IRIS URL - he or she should be redirected to Keycloak. After the user has successfully authenticated, i would like to access his requistes (username, email, roles, scopes) extracted from the JWT token, programmatically. What should be done to achieve that?
