FW: padata-type ?

Title: FW: padata-type ?

Scott,

I asked on IETF kerberos WG about referencing rfc1510. The concensus is that we should not since RFC number will change fairly soon when IESG approve the Kerberos 5, Specification 2 (aka clarifications).

I just got your email which suggests you have chosen to refer to it as Kerberos anyway, so this email is just FYI.

Tim.

That is correct.  RFC's are immutable; once published, an RFC never changes 

(the rfc-editor does maintain a list of errata in published RFC's at 

http://www.rfc-editor.org/errata.html, but the originial documents are 

never modified).

RFC1510 describes Kerberos V, Specification 1.

Once approved, kerberos-clarifications will be published as a new RFC; this 

will obsolete RFC1510 and (in combination with the crypto and AES 

documents) will describe Kerberos V, Specification 2.

In most cases it is desirable in a standards context for normative 

references to be to a particular version of the specification.  For IETF 

standards, you can do this by referring to a particular RFC.  In a few 

cases, you actually want a reference to "the current version", whatever 

that happens to be.  The IETF way to do this is to refer to an STD number; 

however, these numbers are currently assigned only to full Internet 

standards.
