I understand your idea, but it's useful only when another root-privileged
process is able to update the cache contents (like parent process ?).
Otherwise, only per-user cache makes sense when it comes to being useful.

Look above. The other question is what do we expect non-privileged account
to be able to do with samba daemons ?
