While concrete5 can support multiple authentication methods, and has built-in support for OpenID (in addition to the core concrete5 authentication method), there's no framework for building these authentication methods, making their settings available to administrators in the dashboard, grouping them on a login page or managing which authentication methods are available or how they are displayed. The Authentication Framework will change that.
The complete goal for the Authentication Framework is to normalize built-in authentication and OpenID, and make it easy to add and manage third party authentication methods like LDAP, Facebook Login, Twitter login, and more.
