Simon, the problem is that if I enable authentication on the
server side, the clients still connect whether I specify
authentication on the client or not. I debug ntp auth and see
NOTHING. I debug ntp packets and see the same whether I have
authentication on or not.
I'm thinking that if I enable authentication on the server then
none of the clients should be able to sync without authentication.
Like OSPF or RIP2.
I have searched CCO and TAC database for any complete NTP
authentication configs and have found none. I find that curious. I
can't find any, not even partial using NTP authentication.

A common problem is using the "ntp server x.x.x.x" command without
the "key"
e.g
ntp authenticate
ntp trusted-key 1
ntp authentication-key 1 md5 cisco
ntp server x.x.x.x key 1

Can you show us what configuration you are using?

I have 6 routers, one as NTP Master 1 and the others as NTP

I have no problem getting the other 5 to pull time from the master
and clocks all synch up.
However, I cannot get authentication to work. The clients synch
to the master regardless of whether authentication is on or not. I
can't find any good examples of NTP authentication configuration.
I'm sure I'm implementing wrong. Any help?
Thanks!
