The separate database does not make lot of sense to me, why not using the Stage
User tree when it's there, ready for you? I would like to know what is the
motivation and reasoning for using completely separate DB. Besides others, I
think Stage Users area for example checks for login name or UID/GID collisions.
The Selfservice just needs to operate under an identity that has a Stage User
Administrator privilege or we can create more contained privilege that could
just add the staged users and not modify/remove them.
