Hi Astrid, When you say draft-chin-radext-identifier-attr requires all proxies to explicitly support this and test all the software; what do you think of draft-dekok-radext-request-authticator would do to the proxy servers? the connection is hop by hop, each hop has to support the new mechanism in order to have nas-proxy-home_server working with the extended-id in all the mechanisms. Just because the draft-dekok-radext-request-authticator does not explain how to do that, does not mean it can have the original software working unchanged:-) We are talking about the feeling of half-baked;-) Cheers, - Naiming > On Nov 28, 2017, at 12:18 PM, Astrid Smith <AE.Smith@f5.com> wrote: > > Hello, > > I prefer the option laid out in > draft-dekok-radext-request-authenticator-02, due to deficiencies in > the other proposal (draft-chen-radext-identifier-attr-02). > > I'm concerned about the extended Code field it defines: How should > implementations treat messages where this Code differs from the Code > in the RADIUS header?
