[keycloak-user] JPA Authentication Provider

Hi guys, Wondering if it would be possible to create a JPA authentication provider? What I am trying to do is share the hibernate user model between keycloak authentication provider and my application. I've got as far as extracting the models into their own project so they can be used as dependency between my application / authentication provider. Still wrapping my head around JavaEE architecture so forgive me if this next sentence doesn't make any sense... The properties authentication adapter in beta1 examples is a jar which can't really declare it's own data sources. So wondering how I would implement a provider that defines its own datasource? Thanks, Josh
