Hello everyone. I have been tasked to implement Keycloak with custom Storage SPI. Thanks to this beautiful video [KEYCLOAK Implementing Custom User Storage Provider (in-depth) | Niko Köbler (@dasniko)](https://www.youtube.com/watch?v=1UklqPPjcRY&ab_channel=NikoK%C3%B6bler%28%40dasniko%29), I was able to implement and get it to work without any issue.

But the problem is, I need to implement a database connection using Hibernate (or Spring Data) and I tried many times with different configurations, but can’t get it to work.  
I even tried [Multiple persistence units (Quarkus)](https://quarkus.io/guides/hibernate-orm#multiple-persistence-units) and EJB Persistence to get it to work, but it won’t work.

Has anyone tried and made it work? If so, I really appreciate it if you could help me.  
By the way: I am using Keycloak 19.0.1
