All my users are in KC. Not federated.
My app has a “people” table, which duplicate some user properties, like first and last name.
When a user updates his profile in KC, I want this change to be reflected in my app too.
I first thought of creating an event listener, which would then do a REST call to my app on the user update event. But the REST url, credentials etc would be hard coded in de listener, as AFAIK there is no way to make an event listener configurable from the admin interface.
Then I tried to implement a UserLookupProvider and UserStorageProvider, but this interface only has read methods, no update methods.
I also tried implementing a UserFederatedStorageProvider but this one doesnt even show up in the provider list in KC (deployment in KC succeeeds though.
