Joe,

I seriously dooubt anything autokey works properly in the p5 
(production) version. That version has been on a different maintainence 
track than the p127 (development) version for well over a year. The p5 
protocol and crypto modules date from December 2006 and the keygen 
module from August of this year. The configuration and key management 
procedures did change in the summer of 2007 to both simplify the 
procedures and provide nested, separately keyed secure groups. This is 
documented on the current web and in the development version.

I dispair that the production version lags so far behind the development 
version and especially when production maintenance results in 
incompatible module matches. My advice is to use the development 
version, which is in rather good shape.

By the way, I did verify the -H option does work in p127. The discussion 
on the Authentication Options and ntp-keygen pages has been rewritten 
and clarified. You should find things much simpler, more straightforward 
and with consistent defaults.
