nfs mount permission issues

Hello,
We have some new application requirements that require us to use nfs mounts from aix 5.3 and mount to Oracle Linux 5.6.

Do you know why when on the destination ( linux ) box, the root user cannot access directories made by other users in the nfs mounted filesystem ?

I read that there needs to be an option in the /etc/exports file for the source, called -maproot=root.
I tried that, but am not sure of a clean way to have the client read the exports file again to take the new parameter.

Any ideas would be appreciated.

Thanks,
floyd

Never mind, I figured it out.
If i put the option "root=client" in the exportfs file, it works.
