Thanks Evan. This seems like a good start and I'll plan to work to incorporate the proposal in some/similar form into the next revision of the document. Comments, clarifications, etc. from the WG are also always welcome too in the meantime. Or from the AD, who also suggested allowing for the use o

I have taken a stab at some text that will open the door for SAN-based subject identity support. Some minor modifications in section 2.1, and additional metadata parameters in section 2.1.2. Please find that text below. > I scanned through the SPIFFE docs but didn’t any mentioning of OAuth (just

Hi Evan, I scanned through the SPIFFE docs but didn’t any mentioning of OAuth (just plain X.509). What’s your plan for introducing OAuth and mtls? kind regards, Torsten. > Am 13.11.2018 um 00:59 schrieb Evan Gilman : > > Thank you everyone for the feedback. > > I am currently working on the

Sure, I think they could be treated as different different client_auth_methods. But there is a lot more commonality than differences to the point where I think it makes sense to keep it all in a single document and under a single client auth method with just the variation on which name is being use

Thanks for referring us to this spec. How I read it, every way to represent an application identity may require specific verification rules (including typ specific syntactical rules). In my interpretation this means we must explicitly manage expected type and value of the identifier used to ma

Would it make sense for these to be a different client_auth_method entirely? Much the same way that we have private_key_jwt and client_secret_jwt today, both of which use the JWT assertion framework but have very different keying and security assumptions. In the same way, here you’re still valid

Thanks Evan for bringing this to the WG's attention. More or less the same question/issue was raised yesterday in the area director's review of the document as well.

Hello everyone. Very excited to see this draft. It helps tremendously in addressing use cases around oauth client management in machine-to-machine scenarios. Particularly, the PKI authentication method. In reviewing the document, I noticed that the only supported method for identifying a client u
