How can I authenticate MQTT with OAuth?

[ofgirichardsonb]

Thanks for the updated article, but I’m still not having any joy… I am trying to run the perfsdk_c utility the blog article refers to, but a) it’s not clear which of id_token or access_token are required, and b) neither of them work anyway. I still see nothing in the stats, except that there are tokens received that apparently drop in a black hole; they do not report any error, nor do they report success. How can I see some kind of indication what the broker is doing with those tokens? Does no one have a working .NET code sample? Preferably MQTT/OAuth2, but even SMF OAuth2 would be fine.
