http://framework.zend.com/manual/en/zend.auth.html details the Zend-Auth mechanism. As Magento is based on Zend, it is believed that Magento can authenticate through the Zend-Auth system to backend authentication schemes such as Central Authentication System (CAS) http://www.ja-sig.org/products/cas/
CAS is supported by many other platforms such as TikiWiki.
Magento uses Zend as a platform. It is assumed that if something can authenticate with Zend then it will be able to also authenticate to Magento.
To investigate we will begin by looking for authentication information stored in Magento.
