The open source edu.yale.som.auth .NET solution:

• Combines different authentication and authorization providers, e.g. Yale University Central Authentication Service (CAS), Forms Based Authentication (FBA) and Active Directory (AD) into a single login page for SharePoint 2007 (MOSS) and ASP.NET web sites.
• Integrates MOSS or standard ASP.NET web applications with a CAS authentication method implementation to allow users to authenticate via CAS and authorize against FBA Roles.
• Exposes a consistent login experience for users across all your MOSS and ASP.NET web applications
• Can display multiple authentication methods or can be configured to always default to a single method, e.g. CAS.
• Utilizes a plug in interface design that allows you to implement additional authentication and authorization classes to extend the login functionality.
• Provides user processing for FBA Membership, Profile and Roles dynamically during login and/or through batch process via custom FBA administration web parts.
• Allows you to map your existing AD group memberships to FBA Roles for authorization against those Roles in MOSS or standard ASP.NET web applications
• Simplifies MOSS site design, deployment and management by allowing you to expose multiple authentication and authorization methods in a single MOSS web site Zone.
