[keycloak-user] Two realms; one LDAP; one namespace?

Just configured two different realms pointing to the same LDAP directory. Logged into master via LDAP the first time. The second time, logged into another realm with the same user and got an error “Email already exists.” Shouldn’t the realms be independent of one another? It seems like there is a universal namespace for users that crosses realms. Is that intended? What is the “Keycloak way” to handle this situation if it’s by design? -Jason
