Single Sign-On
• Identity management is an emerging challenge at
many institutions

authorization

solutions
• Smaller institutions may not have a need
Blackboard Authentication Framework
®

• Internal database
• Custom authentication mechanism
– Built by clients and by Blackboard Consulting
Services(sm)

Introduction to AutoSignon
• Allows users who are authenticated by a trusted
system to access the Blackboard platform without
needing to log in again (Inbound SSO)
• Based on the WebCT CE/Vista Automatic Signon
Protocol
• Uses a MAC (Message Authentication Code)
generated by request parameters and shared
secret to validate incoming SSO requests before
processing
