CentOS - Jan 2015 - nfs-server in centos 7 - no error message from chown/chmod commands on clients

Hi,

we are using centos 7 as an nfs-server.

Chown / chmod on all linux clients (RH5,6, Ubuntu 14.04) don't get any
errors from unallowed chown/chmod commands. Return-code is 0.

e.g.
ls -al test.txt
-rwxrwxr-x 1 sanderso users 0 26. Jan 15:09 test.txt
chown otheruser test.txt
echo $?
0
ls -al test.txt
-rwxrwxr-x 1 sanderso users 0 26. Jan 15:09 test.txt

last posting here describes the error.

Can anybody help with that?
I don't find much information regarding this topic and can't believe.
Are there so few people who still use nfs services?
