Hi. If every of your apps has separate users db what do you want to have in ideal circumstances? Do you databases include equal users? For example if you want to have "merged" user storage you could implement custom user storage for every db, so when user would be redirected to keycloak for login, keycloak will consecutively try to extract user data from this user storages. And you will have opportunity to set priorities of this storages in keycloak admin console. As for examples you should check examples from git repo and also carefully read tutorial in docs. Also your implementations could have ability to create users in keycloak itself on the fly while extracting users from user storages (so later you will have merged user db in keycloak). Dee details in docs (Server development -> User Storage Spi -> Import Implementation Strategy). 19.04.2017 11:35, rohit chaudhary пишет:
