Problem with Linux >= 3.3 as NFSv4 server

[Norbert Aschendorff]

I already had a problem with this, but this is fixed: 1. The hostnames
are correct 2. in the debian /etc/idmapd.conf, the right domain name is
specified 3. The names are transmitted correctly -- tested with
Wireshark. If the problem was wrong domain names, I had found it because
I always take a look at the traffic if I have a problem with network
stuff. And (as mentioned), I already had the name problem and therefore
the knowledge how to detect and fix it.

Nevertheless, thank you for your answer.
