How to configure wsHttpBinding with Windows Authentication:


Here is a simple service configured on IIS with windows authentication. When using wsHttpBinding, the security mode must be “Transport” for Windows Authentication on IIS to be used. Also the website needs to have a server certificate configured.


If you use any other security mode you will receive the following error message.

Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service.


If you are receiving the following error message, make sure the website bindings are configured for https.

Could not find a base address that matches scheme https for the endpoint with binding WSHttpBinding. Registered base address schemes are [http].
