[ntpwg] Problem with Symmetric Key in both NTPv4 and Autokey drafts

[Danny Mayer]

I have been reading the autokey draft and it mentions the symmetric key 
authentication referencing the NTPv3 RFC 1305. See P7 Section 3 item 1. 
However that RFC is obsoleted by both the NTPv4 draft and the autokey 
draft (though I'm not sure an Informational RFC can obsolete a standards 
track RFC). The NTPv4 draft mentions in Section 7.3 (P.17) that 
symmetric key it is described in the draft when it does not. It looks 
like we need to pull parts of RFC 1305 Appendix C into the NTPv4 draft 
if that's what needs to be copied. I missed this yesterday when going 
through the document.

Sorry to hold things up, but that's an important piece of the NTPv4 
protocol.
