Thank you again.  Is it correct to infer from these lines from the
provided reference that the __ ntpsigndsocket __ setting is supported
in /etc/ntp.conf?


1415 	/* Path to sign daemon rendezvous socket */
1416 	#define NTP_SIGND_PATH "/var/run/ntp_signd"

I previously set this in /etc/ntp.conf without error, but that does
not mean that it is recognised:

# grep ntpsigndsocket /etc/ntp.conf
ntpsigndsocket  /usr/local/samba/var/lib/ntp_signd/
