Portlet Authentication and SSO

Abstract

In this section, we will introduce a few important details relevant to the authentication process and Single Sign On (SSO) implementation. The SSO is a popular feature that was established in the portal standard JSP 168 as a mandatory feature. This functionality enables the user to authenticate only once to all Web services and back-end applications to which he or she requires access. The authentication code is propagated to all services for which the user has access permissions. This means that users can log on only once and be known to the various parts of the portal server with the same user credentials.
