I am working on porting a web application to the JBoss Portal. The web application has a login screen which provide authentification. I have successfully created a portlet which displays this authentification jsp and it works. We are planning to refactor the web application into separate portlets and I am wondering how to implement the concept of single sign-on. What does this mean and how is it generally implemented?
