Hello, I have worked on an extension proposal for HTTP with SASL, and will be presenting the work in IETF next Friday. This is an online presentation where I will try to convince the audience of its usefulness, without getting into all the details. You are of course welcome to join in. Meeting info, https://datatracker.ietf.org/meeting/107/session/secdispatch Slides, https://datatracker.ietf.org/doc/slides-107-secdispatch-http-sasl/ Draft, https://datatracker.ietf.org/doc/draft-vanrein-httpauth-sasl/ FYI, this could be combined with other work to support Realm Crossover through SASL, https://tools.ietf.org/html/draft-vanrein-diameter-sasl Cheers, -Rick
