# SharePoint 2010 automatic sign-in with mixed authentication
SharePoint 2010 comes with Claims based authentication and the option to have multiple authentication providers for the same url. Unfortunately this setup breaks transparent authentication in an intranet environment. This project aims to solve this issue.

When using Windows Authentication for an intranet environment this brings back transparent authentication based on the Windows credentials.

## Background
SharePoint 2010 comes with a nice new feature that aims to solve this problem: Mixed Authentication. It allows for the configuration of multiple authentication providers (Windows authentication, forms authentication, trusted Identity providers) together using the same url, without having to extend the web application. Both external and internal users would access the web site on https://intranet.company.com for example.

By default the user has to choose the authentication method when upon logging in.
While this is very nice, and a great improvement over the previous version, the downside is that there is no more transparent authentication in an intranet environment.

With the correct browser settings is it possible to log on automatically when using windows authentication.
In Internet Explorer it can be configured in the security settings of the Local Intranet zone. These settings can also be pushed through group policies.
If the intranet is configured correctly, or “detected automatically”, all login attempts will transparently use the windows identity.

Each time a user tries to access the intranet, each time he tries to open a document stored on the intranet, he gets the same login popup.

## Special thanks
This project is based on sample project created by (Bryan Porter)[https://blogs.msdn.microsoft.com/brporter/]. Full credits to him for developing this great solution. We had to extend it relatively little to make work in a live environment. The original sample and the blog post about it can be found (here)[https://blogs.msdn.microsoft.com/brporter/2010/05/10/multiple-authentication-methods-in-sharepoint-2010/].
