NTP Authentication

Along the lines of NTP. I am wondering if I can get authenticated as well as
unauthenticated time from the same time source. In other words, can I have
some client who use authentication against NTP server updates and other
client that don't? It seems to me that I remember if the server has a key,
all the clients will need the key.

I am asking because we have a situation where we do not use NTP
authentication for our devices but it appears the IDS sensor (4210) requires
authentication if your going to use NTP as a time source. I was thinking
either of a configuration that would allow some clients authenticated and
some not OR a master that synchs with the current master but provides
authentication to those clients who require it (the sensors).

Thoughts, comments possabilities?
