The demo conatains two different solutions, one uses the spring namespace, the other configures explicilty Spring security filters and providers.

The main issue to solve is how store the OpenID attributes returned from the OpenID provider to the Sprin UserDetails object.

Spring Security Name Space OpenID Setup

Through the element <openid-login/> Spring  auto-configures an OpenIDAuthenticationFilter and an OpenIDAuthenticationProvider. The element <attribute-exchange/> contains all the  OpenId attribute element to ask to the provider.

<security:http>
 <security:anonymous enabled="false" />
 <security:logout />
 <security:openid -login authentication-success-handler-ref="authenticationSuccessHandler" login-page="/login" authentication-failure-url="/?login_error=true" >
 <security:attribute -exchange>
 <security:openid -attribute name="email" type="http://schema.openid.net/contact/email" required="true" />
 <security:openid -attribute name="firstName" type="http://axschema.org/namePerson/first" required="true" />
 <security:openid -attribute name="lastName" type="http://axschema.org/namePerson/last" required="true" />
 <security:openid -attribute name="language" type="http://axschema.org/pref/language" required="true" />
 </security:attribute>
 </security:openid>
 <security:remember -me key="alessandro-vincelli-openid" />
</security:http>

I didn’t like 4.0 and 4.1, too many bugs and low level of usability, but the 4.2 rocks.

I installed the 4.2 on Kubuntu 8.10 without problems.

You can explore KDE 4.2 also watching some nice Video Guide.

Thanks to the KDE communty for this very good product.

Segnalo inoltre la lettera del Presidente Napolitano che firma il sostegno all’inizia e al mondo del Software Libero. Personalmente ho gradito molto.
