I don't think the term "authorized" makes the situation any clearer. Let's take a concrete example: an IMAP client attempting to connect to and use the IMAP service at "example.com". It needs to lookup the "_imap._tcp.example.com." DNS SRV record to figure out which servers and ports to connect to. And in the presented certificate, it needs to expect to find an SRVName identifier with "_imap.example.com" as its contents, where the _Service and Name components were the same ones it used in the SRV query. There is no need to figure out who authorized what. -- Shumon Huque University of Pennsylvania. _______________________________________________ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf
