Did you also enable signed sockset support in ntp.conf?

ntpsigndsocket /var/lib/samba/ntp_signd/

I note that's a rather old version of Samba.  What version of ntpd are you 
running?  If it's too old (<4.2.6), it might not even have signing 
support.  Also if you are using distro packages, you may want to download 
the source package and make sure it was compiled with signing support.  I 
know at least some older 4.2.6 distro packages on RHEL/CentOS 6 were not 
(though the current ones are).
