title: Integrating openID and oauth as website login, signin and authentication system
body: <p>First of all let me start by saying that this question is not about different openID and oAuth implementations. There are many classes about these.</p>
  
  <p>My question is what to do after authenticating a user:</p>
  
  <ul>
  <li>How to add this user to the user table in the database? </li>
  <li>How to handle different logins for the same user? <em>(Remy Sharp's <a href="http://remysharp.com/2007/12/21/how-to-integrate-openid-as-your-login-system/" rel="noreferrer">example</a> suggests
  something for openID)</em> </li>
  <li>How to combine oAuth and openID in the database?</li>
  </ul>
  
  <p>Any ideas?</p>
