NTPD - cap_set_proc() failed to drop root privileges: Operation not permitted

Problem description
NTPD doesn't start on a virtual machine:
service ntpd status
ntpd dead but pid file exists
service ntpd restart
Shutting down ntpd: [FAILED]
Starting ntpd: [ OK ]
tail /var/log/messages
... cap_set_proc() failed to drop root privileges: Operation not permitted
Resolution
vi /etc/sysconfig/ntpd
locate the following line and comment it out:
# OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid -g"
Now the restart will work:
service ntpd start
