A year and a half ago I posted the Visual guide to Windows Live ID authentication with SharePoint 2010 series, a post that got a tremendously amount of hits (and still gets) and tons of comments (and new ones still coming in). It showed quite a cumbersome way to Live ID enable your SharePoint 2010 Web Applications using the Microsoft Service Manager, MSM, (which works some times and some times not). Although it did/do work it is not the best way to enable Live ID authentication to your SharePoint 2010 web site. The MSM required you to first test in their INT environment and get approval before putting it into production, and you had to follow a set of guidelines on how to use Live ID logos etc etc, not mentioning all the manual configuration.
