<a name="line-39"></a>The OpenId authentication scheme works as follows:
<a name="line-40"></a>
<a name="line-41"></a> - the user tells us which OpenId provider they want to use
<a name="line-42"></a> - we call 'getForwardUrl' to construct a url for that provider
<a name="line-43"></a> - the user is redirected to that 'url' -- typically a 3rd party site
<a name="line-44"></a> - the user interacts with site to confirm the login
<a name="line-45"></a> - that site redirects the user back to a url at our site with some 'claims' in the query string
<a name="line-46"></a> - we then talk to the user's OpenId server and verify those claims
<a name="line-47"></a> - we know have a verified OpenId identifier for the user
