[keycloak-dev] Users and Realms

[Stian Thorgersen]

For the new store I was actually thinking that we could completely detach
users from the realm. Rather than have a user store as part of the realm we
would just have an optional Keycloak user store that could be attached to a
realm in the same was as any other user store.

We shouldn't make any such big changes to the current store though and
rather reserve that to the next store.
