[CentOS] sssd run level get turned off automagically

CentOS 6.5 (AMD64)
LDAP DS:  via SSSD

When I did the OS installation (client site), I had turned the service
ON with 'chkconfig sssd on'  and 'chkconfig sssd --list' showed that
it was ON

However, whenever the server has been 'hard' rebooted, 'service sssd
status' shows that it is not running.    'chkconfig sssd --list' shows
it is OFF!

I don't understand how it is automagically turned off.  Any ideas what
could be the problem.
