We had password-less broken after nfs. The issue was identified was identified and fixed.
The issue was that we did not configure the workers to start the rpcidmapd on boot. Also we didn't configure the /etc/idmapd.conf file on workers to change their domain. Both of these contributed to changing the owner of all the mounted file(/home) to 'nobody'. The way to fix it is to do the following on both the workers.
#Make the rpcidmapd start on boot
sudo chkconfig rpcidmapd on
#Edit the idmapd.conf
sudo vim /etc/idmapd.conf
#Uncomment and change the domain param to cluster8.unl.edu
Similarly, edit the idmapd.conf on head node.
Restart nfs and password-less should start working.
