Hi,
I am growing weary of some error messages in my syslog - its showing:

Jul 3 15:16:38 web rpc.idmapd[14535]: nss_getpwnam: name 'nobody' does not map into domain 'mydomain.com'

I have check, my hostname is correct as mydomain.com and I even added a valid entry in /etc/hostname . I have edited my /etc/idmapd.conf to reflect this domain name, this error message log every 10minutes and its becoming frustrating, I do not know why or whats causing it, the nfs server is working ok, with correct entries and now message in the log.

I am using centos6

-- Ofcoure, i have substituted mydomain.com with my real domain

A process is probably trying to perform some action as the user 'nobody'. Does that account exist on the system?

Yes, I have the nobody user, it runs Nginx, and php-fpm among other things.

The 'nobody' mapping message is logged every 10 minutes, I have checked my crons and dont seem to find anything that runs every 10 minutes,how can I find out what process is causing the error, and most importantly, how do i map nobody to mydomain.com?
