[keycloak-user] association of application user an keycloak user

Hello, Is there any concept or standard way on how to link/associate users residing in an applications own DB to the users registered in the keycloak database (residing in keycloaks USRR_ENTITY table), e.g. something like the good old JDBC-realm?
