title: Implementing a membership system using OpenID
body: <p>I'm looking to implement a membership system using OpenID for my ASP.NET application, similar to the system used here on StackOverflow. I'm aware that the OpenAuth library is generally recognized as the way to go, but I'm having trouble figuring out how to implement it.</p>
  
  <p>I use NHibernate to persist my domain objects. I have a Users table with a username column, email column, etc. I'm not sure how to integrate OpenID with my own users table, and I haven't found any good tutorials on this. Does anyone have any experience with this? What is the best way to go about doing it?</p>
