I can try to play around with the idmapd.conf and set the fsid=0 option. What bugs me, though, is that neither option is enabled on the SL6/RHES6 server and I am able to mount via nfs4:

(Of course, it could be that SL6 did things a little differently with their distro's implementation of NFS4, but I doubt it).
