Richard Thomas has posted another Solar framework short today. This time it's about OpenID and how you cn easily create a custom adapter that integrates directly into the framework to support it.

Solar makes heavy use of Adapter based classes, Solar_Auth is one of these. This makes adding additional methods pretty easy and allows you to borrow from other Frameworks without having to Hack in a third party auth setup, You can use the basics provided by Solar.

He includes a code example showing how to extend the Solar_Auth_Adapter component to create an OpenID adapter you can use as a part of your authentication process. His Solar component encourages code reuse too by using the Zend Framework native OpenID implementation as its authetication functionality.
