[keycloak-user] Ability for user to have multiple IDP's of the same type per user

Just wondering if anyone else would find this functionality useful. I have a custom IDP (not Google but similar, let's call it Acme IDP) that allows a single email to have multiple identities. For example me(a)acme.com could login as an ADMINISTRATOR or a PURCHASER with the only difference being what Keycloak calls the federated_user_id returned from ACME. Currently this isn't supported in Keycloak because of the foreign key constraint on federated_identity table (identity_provider, user_id). If this constraint is changed to (identity_provider, federated_user_id, user_id) and the FederatedIdentityEntity.java class is changed to represent the new constraint then voila I can support multiple IDP's of the same type per user. Just wondering if this has ever come up for anyone else before. Regards, Ben
