Federated Identity Authentication with ADFS

That just sounds cool... But it appears that it might work really cool too! Take a look at Keith Brown's article Single Sign-On -- A Developer's Introduction To Active Directory Federation Services. This is more of a business to business idea but I think it could work internal to a company as well. I'm always looking for ways to leverage single sign-on capabilities. Everyone hates typing their password in 20 times a day which is about how often I do. I'm glad people continue to innovate in this area.
