Integrated Windows Authentication with Claims Based Authentication in SharePoint 2010 error (IE)

Hi

In case you have a problem "signing as a different user" in SharePoint 2010 Web Application that uses "Claims Based Authentication" you will need to turn off the "Integrated Windows Authentication" option in Internet Explorer (As shown below). Without doing this, you wont be able to sign is as a different user.

This does not apply to other browsers and it is an IE issue.

Geneva now supports SharePoint 2007

Geneva Team released beta 2 of the server and the framework. In the list of new features is supporting SharePoint 2007. This means that SharePoint 2007 could potentially connect to a STS server and be a Claim Based application.

SP2 for MOSS was released a while ago, and in the enhancements was a better integration between client applications and FBA for SharePoint.
