Windows SharePoint Services (WSS) V3 contains several new features around authentication and authorization that make it easier to develop and deploy solutions in Internet facing environments, especially extranets.

WSS V3 is built upon the ASP.NET 2.0 Framework, which allows the use of forms-based authentication (FBA) to authenticate users into the system. By riding on top of ASP.NET 2.0’s pluggable authentication provider model, you can now support users stored in Active Directory as well as SQL Server, an LDAP directory, or any other directory that has an ASP.NET 2.0 Membership provider.
