idmapd is used to convert client usernames/IDs into server
usernames/IDs. This allows things like a user with UID 100 on one
client to map to the same user with UID 200 on another client. It's
not, strictly speaking, necessary; but it's very nice to have,
especially in large environments with diverse clients.
NFSv4 will work without it.
