The Authentication package that comes with the ASP.NET in VS 2012 is excellent!  It saves a lot of effort for everyone.  Now we can have Live Id, Google, Facebook and Twitter authentication without a single line of code!  Previously I had to sweat just to roll out a Live Id one.
Unfortunately I now have a my web site that can access data via web services only.  The server is cordoned off and only port 80 is opened to the organization's internal network.  How can I extend Microsoft.AspNet.Membership.OpenAuth to use web services instead of direct SQL Server access?  Or is the source code available?
Thanks.
