[keycloak-user] Additional jpaConnectionProvider for UserFederation via database

[Stian Thorgersen]

Are you deploying it as a module or by dropping it into
standalone/configuration/providers? The latter will pick up the
persistence.xml from Keycloak classloader so that's probably why it doesn't
work. Try deploying as a module instead as that's the only way you can get
full control of the classpath
