Uncomment this lines for a more much more verbose logging in /etc/sysconfig/nfs:

d. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: do you have a keytab entry for nfs/<your.host>@<YOUR.REALM> in /etc/krb5.keytab?
Double check your /etc/krb5.keytab. On the server it must have the nfs/server.exemple.net key and on the client it must have nfs/client.exemple.net.
In idmapd.conf, leave it as the default: [General]
Verbosity = 0 Pipefs-Directory = /var/lib/nfs/rpc_pipefs Domain = localdomain
[Mapping]
Nobody-User = nobody Nobody-Group = nobody
[Translation] Method = nsswitch
Believe me, I've tried to understand[1] why Domain must be "localdomain" but I've no been lucky.

I made the requested changes and when I start the nfs services (/etc/init.d/nfs start) I get the same error messages. I made sure that I have used kinit nfs/nfs.example.net -k -t /etc/krb5.keytab and verified that the principle was loaded by using klist. I have disabled SELINUX & iptables to make sure that neither are interfering with this. Thanks again for the help!
