Hi Marek,
using an application managed EntityManagerFactory appear to be working. I
created a UserStorageProviderFactory that is managing a entity manager
factory and when I use the entity manager in the UserStorageProvider the
transaction is managed by the container transaction manager that also
manages the Keycloak transactions. Why am I certain about that? Had a few
errors in the beginning about 2 datasources trying to enroll as last resort.
The main ingredients in this gist.

The trick is to tell hibernate

where to get the JTA platform transaction manager from.
Does that look about right? I have a feeling it could be simplified with
some CDI magic ...
Cheers Niels

Yes studied that one before asking the question, its close but not
close
enough. I think I will get away with creating an application managed
persistence context with container managed transaction. Then in the
provider factory I will read the DataSource name from config and create the
entity transaction manager. Am just not too sure if it'll work with the
things you do in Keycloak to access these provider EJBs. I kinda need 1
stateful session bean for each provider instance added to the realm and
that needs its on EntityManagerFactory which enrolls the entity manager in
the JTA from Keycloak. Will report back if I can get something working.
Thanks Niels
