Thanks, Could you add bbh7rqj@socrates.bell-atl.com to the list? This is 
not me, but a colleague (Chris Davies), who is monitoring NTp more closely.

Will do.

We use the current authentication scheme available with NTP, and realize 
that the notion of the security of the  time service relying on the 
security of the security service which relies on the security of the 
time service is troubling! However, in the absence of any name/time/security
services designed together in a secure fashion, we feel it is probably 
easier (administratively speaking) to have a single security mechanism (in 
this case Kerberos).

Thanks,
