Steps to migrate from current system to keycloak API with multiple roles, organisations

Scripts for keycloak

  3. Add mapper -> By configuration -> User Attribute
  4. Name, User Attribute and Token Claim Name: enter all these fields with roles
  5. All switches are true except for Add to lightweight acces token.
  • Repeat these steps for the groups attribute
