This article describes what is SSO and the top five benefits of Using Single Sign-On to Enhance Internal User Experience.
SSO
Today's Internet world, urges Single Sign On for multiple web applications as an inevitable requirement. It's not an easy task to implement SSO (Single Sign On), if the web applications are developed on different platforms. User authentication and maintenance of user's "logged in session" on web applications, is completely dependent on HTTP cookies. No web browsers allow to read cross domain cookies, as if it allows, it's a security issue then. I.e; Two web applications cannot share a single cookie, if they are deployed in different domains.
