[keycloak-dev] SCIM v2 support

Hello, in a customer project we use keycloak and need a SCIM (System for Cross-domain Identity Management) API. Currently we write a wrapper API and a custom endpoint providing the SCIM functionality. We wrote a extension of the UserEntity, UserModel and an extension of the JpaUserProvider. This strategy seems not ideal and the nicest way is to add this extensions to Keycloak. This is already suggested in https://issues.jboss.org/browse/KEYCLOAK-2537 Is anybody out there who can guide me, what coding would be necessary to contribute the SCIM functionality? Currently I think we have to: - extend the UserEntity with all SCIM attributes. This will result in additional tables/entities for complex attributes e.g. Address, Name, Email - extend the UserModel to povide the additional attributes - implement the new SCIM endpoint /Users - make the additional attributes available via Admin REST API /users - extend views to be able to edit SCIM user attributes using the web ui - … - All the above again for the Groups endpoint… This also seem to be major changes. To big for one Pull Request. How do you like to handle this? Best regards, Sebastian
