Hi, I am checking Keycloak user federation with openldap sourcce. It worked fine & synced users but some users are not synced as they hace same email id as already sunced users. I see this constraint in Keycloak postgresql user_entity table: CONSTRAINT uk_dykn684sl8up1crfei6eckhd7 UNIQUE (realm_id, email_constraint) But we need only uid (userName in Keycloak) unique. Is there anyway to configure that email can be duplicated?
