ArgumentNullException in RewriteModule when callback from openid authentication
For 6 R2 you will be out of luck. Best option is to upgrade Epi. You can setup a bridge concept like this: http://krompaco.nu/2014/10/owin-authentication-on-older-episerver-sites/

I have a site running EPiServer CMS 6 R2. They wanted SSO from Azure AD.
I went with the solution with openid and owin.
When pressing the login in with azure button, i get redirected to the microsoft login screen and authenticate myself. And after that i get redirected to a static page on the site. Where the purpose is to add additional user information and create the user in our db.
But when I get redirected to the site I get an error in th URLRewriteModule.

I have no idea why I get this. The information from the authorization is stored in form data of the request, could it be this that's creating the issue. Because i can navigate to the page without this.
I have tried using a handler(ashx) as well and still get the error.
