Multiple Authentication Providers in SharePoint 2010, Part II
The folks over at Orbit One Internet Solutions took my blog posting regarding automatic selection of authentication providers in SharePoint 2010 and really ran with it. They've posted what looks to be a fine solution adding and extending all the things that I pointed out would be needed in order to turn my original sample into a full solution - read all about it over at the OrbitOne Blog (https://www.orbitone.com/en/blog/archive/2010/06/23/sharepoint-2010-mixed-authentication-automatic-login.aspx).
Great job, guys!
