Single Sign-On Across Multiple Domains

Without single sign-on, users are often required to log on and enter their credentials multiple times as they access different applications and resources on separate servers in different cookie domains. The ability to pass single sign-on information across multiple cookie domains enables a user to authenticate at a site in one cookie domain, and then go to a site in another cookie domain without being rechallenged for credentials. For the user, this seamless navigation makes related sites easier to use.
