Administering : Authentication in Focal Point : Authenticating by using Web Single Sign-On
  
Authenticating by using Web Single Sign-On
If you are logged in to a corporate network, you can automatically log in to the Focal Point server by using Web Single Sign-On (SSO). Web SSO eliminates the need to administer and remember a separate password.
The user name is sent to Focal Point by using three HTTP headers. When you are authenticated, you are directed to either a list of workspaces or a specific workspace, depending on your settings. If you are not authenticated, you are directed to the Login page.
