Active Directory Federation Services (ADFS)
Applies To: Windows Server 2003 R2
Active Directory Federation Services (ADFS) is based on the emerging, industry-supported Web Services Architecture, which is defined in WS-* specifications. ADFS helps you use single sign-on (SS0) to authenticate users to multiple, related Web applications over the life of a single online session. ADFS accomplishes this by securely sharing digital identity and entitlement rights across security and enterprise boundaries.
