I have two servers running RHEL6. I have **root** access to both. The main server, which I will refer to as `server`, is a database server. The application server, which I will refer to as `client`, mounts a directory from `server` via NFS.

There is a user, `appuser`, on both `client` and `server`. However, `appuser`'s UID on `client` is `502`. `appuser`'s UID on `server` is `506`.

Both users need read and write capability on the NFS share. To facilitate this, I made the share owned by `appuser` on `server`.

Running `id appuser` on each yields: `uid=506(appuser)`.

Of course, `client` does not recognize that ownership, since `appuser` has a different id on `client`. So I did the following:

* Changed UID of user in /etc/passwd on `client` to be 506.
* Changed ownership of `appuser`'s $HOME on `client` to be `appuser` again so that I could log in.

Now, when I go to look at the NFS share from the `client` side, I see that it is owned by `502`. `502` is the OLD id for `appuser` on client. I can't change ownership of the NFS share from `client`, since that is a volume that physically resides on `server`.

I need to make sure that the NFS share shows ownership of `appuser` from both `server` and `client`.

What step have I missed since changing the `appuser` id on client?

**NOTE**: I have not rebooted `client` (or anything else.)
