Umbraco 8 Back Office Single Sign-On using OpenID Connect

An example customization of Umbraco 8 using OpenID Connect to implement single-sign on for the back office. In this example, the OpenID Connect server is assumed to be https://github.com/auroris/OpenIddict-WindowsAuth.

Rationale

I wanted to have active directory single sign-on without having to set up a service account or use active directory membership providers. This example is geared for my OpenID Connect server, but can be easily generalized for any OpenID Connect server.

Customizations to the default Umbraco 8 installation

The following files were added to App_Start:

• OpenIDAuthConnectExtension.cs
• UmbracoCustomOwinStartup.cs

Web.config was modified as follows:

• appSetting\owin:appStartup was modified from UmbracoDefaultOwinStartup to UmbracoCustomOwinStartup.
