Passing parameters on login with OWIN

Hi There,

I’m using Microsoft.Owin version 4.1.0 in my Webforms Asp.Net (.net 4.7.2) web application.

I found lots of examples for MVC (most of them can be used in my application) but not so many for webforms. I’ve managed to authenticate my application with Auth0 but I bumped into an obstacle. I want to pass parameters on logon and get back it on successful authentication. I found some examples but at the moment none of those are working for me.

Here is what am I using:

var properties = new AuthenticationProperties() { RedirectUri = ConfigurationManager.AppSettings["redirectURI"] };

properties.Dictionary.Add("someparameter", "some_data_to_pass"));

Context.GetOwinContext().Authentication.Challenge(properties, "Auth0");

also, I’m trying to access this dictionary on RedirectToIdentityProvider and try to pass it to the middleware

if (notification.ProtocolMessage.RequestType == OpenIdConnectRequestType.Authentication)
                        notification.ProtocolMessage.SetParameter("audience", apiAudience);
                        notification.ProtocolMessage.SetParameter("test", "testparam"); // here I try to pass the previously set param from the properties.Dictionary but don't know how so I just pass the 'test' param

After successful authentication, I’m looking for the parameters in here

var data = HttpContext.Current.GetOwinContext();

Not sure if I’m on the right track or I’m completely wrong.

I would greatly appreciate any help.
