My NFS4 mounts are not using any true NFS4 features, however. My problem isn't a permissions issue -- it's the fact that the mount on the client is read-only. And NFS4 doesn't rely on numerical UID/GID matching anymore. It uses the username string (via rpc.idmapd). In any case, both the usernames and UIDs/GIDs match on these two systems. -- Joshua Baker-LePain QB3 Shared Cluster Sysadmin UCSF
