How can one develop a "single sign on" component similar to Yahoo.com where you can log-in to one service (email) and use other services (greetings, calendar etc) w/o logging on again. My guess is cookies with JSP/Servlets, am I right? Are there any other ways? Can someone elaborate in details a bit? TIA, - Manish
If you're going to develop a robust SSO model from scratch, you're going to spend the kind of money Yahoo spent to do it. Take a look at the products out there that offer them. The key element is a properly schematized data store, unless you only want session-based SSO. A couple of products that do this work: Netegrity's SiteMinder and Sun ONE Identity Server. Novell has one too.
