You need to learn about "uid", "gid", and file system permissions.
"The user" and "the groupo" that own a file are stored, on the NFS
serrver's file system, as numbers. Those numbers are tied to group and
owner as far as the login name and login user's groups by
"/etc/passwd", "/etc/group", and lots of different network tools that
can also do that.

If the user name on the client *has the same uid and group gid
memberships* as the server expects, then they'lll typically have
permission to write to those directories. This is much like file
ownership on a local directory. If someone else owns the directory,
*and did not allow write access to others*, others will not be able to
write there.

In this case, I would do "ls -al /data" and see who owns it. Then I'd
look up the man pages for "chown" and "chgrp" and "chmod" to get a
handle on what you want to allow and prevent.
