Hey, I have a requirement for building a cross-user multi-tenant application (i.e. users can be shared across tenants if needed).  
Since the same user can be shard across more than 1 tenant, implementing multi-tenancy using 1 realm per tenant is not an option.  
I was curious about whether it’s possible to map specific users to specific clients, restricting access to client they’re not mapped to.

There are new features related to multi-tenancy [1] in version 25. It’s still in preview, and there are many points on the roadmap to address [2], but you can review it and check if it helps you.
