Configuring Keycloak for GeoNetwork: Role-Based Access Control, Sub-Portal Management

[sq1ea]

Hello. I am looking for specific documentation on configuring Keycloak for GeoNetwork, particularly regarding role groups and sub-portals. Is there any detailed guide or best practices on how to set up role-based access control (RBAC) and manage multiple sub-portals within GeoNetwork using Keycloak?

Additionally, is it possible to automatically redirect a user to their assigned sub-portal after login based on their group or role in Keycloak? If so, how can this be configured?

Any references or recommendations would be greatly appreciated.
