All the examples I've seen using Microsoft's OWIN OpenID Connect Middleware (i.e. the app.UseOpenIdConnectAuthentication) use either the Authorization Code, Implicit Flow or Hybrids Flows.
Does this middle ware also support the Resource Owner flow and if so are there an examples?
OpenID Connect specification itself doesn't support the Resource Owner flow. Therefore I don't expect any vendor to implement this. http://openid.net/specs/openid-connect-core-1_0.html
