We're using Kerberos to authenticate the NFSv4 shares, which seems to work fine. The usernames of the clients need to exist on the server though (but doesn't have to have the same uid as on the client) - you can probably set up a centralized user database with ldap, sssd, ipa or something like that - we havn't done that yet though.
