Trying to implement OKTA in one of the existing ASP.Net Webforms. This was successful in a test application when I followed the instructions in the link https://developer.okta.com/blog/2018/08/29/secure-webforms-with-openidconnect-okta
I have implemented the same in our application and I could see the redirection is happening without any issue. But Request.IsAuthenticated is always coming as false, also not seeing any claim information in Thread.CurrentPrincipal.
What should be the authentication tag in the web.config when implementing okta ? I currently has this as Forms authentication.
This blog post series goes into a lot of detail on how to migrate a Web Forms project that uses Forms Authentication to OWIN. You may have already done these steps, but if not it is worth reviewing
