Why Azure AD v2.0 display this error message: AADSTS50011: The reply url specified in the request does not match the reply URLsconfigured for the application?

The root cause of this error is that you forgot the add the "redirect_uri" in your authentication request to Application ID settings on Azure AD.

For example, if http://fyicenter.com/openID_receiver.php was not added to your "OpenID Test" application ID setting as a "Reply URL", and you are using it in your authentication request as the "redirect_uri" parameter, you will get the following error:

Request Id: db18f633-e264-472d-8591-6e5369760f13
Correlation Id: db18f633-e264-472d-8591-6e5369760f13
