NFS - mount: permission denied

[Clodoaldo Pinto]

I can't mount an exported fc5t3 server nfs share from a fc4 client. It
was working when the server was fc3.

[root at dkt ~]# mount -t nfs4 s0:/home /mnt/s0
mount: permission denied

The server is fc5t3 and the client fc4. SELinux is disabled in both.

Server fc5t3 config:
