Yup. id-kp-serverAuth is always the server working group, not the S/MIME group.
I’d actually like to split id-kp-serverAuth into id-kp-serverAuth-browser and id-kp-serverAuth-noBrowsersInvolved. It would make life much simpler. -Tim From: Public [mailto:[email protected]] On Behalf Of Ryan Sleevi via Public Sent: Thursday, May 17, 2018 10:18 PM To: Phillip <[email protected]> Cc: CA/Browser Forum Public Discussion List <[email protected]> Subject: Re: [cabfpub] For Discussion: S/MIME Working Group Charter On Thu, May 17, 2018 at 9:53 PM, Phillip <[email protected] <mailto:[email protected]> > wrote: We seem to have a terminology issue here. What is a server? This is obvious in HTTP but far from obvious in the context of email because there is an inbound and an outbound ‘server’ and it acts as a client and a server at different times. I'm afraid that discussion misses an important word in the discussion - server *certificate*. That word helps us clarify that we're speaking about certificates and their capabilities, not about the different flows in different protocols. If I use an id-kp-serverAuth certificate with a SAN of "www.google.com <http://www.google.com> ", this does not somehow mean I exempt from the BRs or the existing scope of the server certificate working group. So I think we can avoid such discussions about the terminology of servers, and instead focus on the certificates and the existing charted working group, which handles such certificates, regardless of the service context or the role within the protocol. I agree that certificates used to authenticate Mail Transport Agents are properly part of what the Server WG is specifying. But they may be used by a host acting as a TLS ‘server’ or ‘client’. Another little oddity is that we are assuming that the entity a CA validates and issues certificates to in the S/MIME world is properly the end user rather than the organization. That might not be the right approach. If what the CA is effectively validating is ‘example.com <http://example.com> ’, and not ‘alice@’, maybe it is better to perform validation on the organization. I think that's something that could be discussed by the S/MIME WG - with a refined charter scoped to S/MIME BRs. That discussion does not seem to conflict with such a charter scoped simply to the BRs, as what you're discussing is validation methods, which would be rather premature to discuss in the absence of such a chartered group.
