title: What should I set REALM to, using LightOpenID, for Google url's to remain consistent, for storage in my database?
body: <p>Recently, I noticed that when storing the resulting identity in my database, Google would sometimes return a different identity for the same user, resulting in two database entries for a single user.  </p>
  
  <p>After a little research, I figured out that Google uses $openid->realm along with the username to create the identity.  And by default the realm becomes the URL of your website.  Using LightOpenID, what should I set $openid->realm to for the resulting Google identities to remain consistent, so that I can store them in my database?  Can I just set 'realm' to whatever I like?  Or does it have to relate to my URL?</p>
