Single sign-on is becoming an important issue for corporations and Java developers. Corporations require applications to be secure. Users demand applications to be easy to use. Usually, the more secure an application is, the more difficult it is to use. For example, users are inundated with remembering multiple logins to different systems. Part 1 of this article (JDJ, Vol. 6, issue 11) provided readers with a conceptual understanding of single sign-on (SSO). In Part 2 we explain the programming and setup issues related to SSO for Web and standalone applications. With this knowledge, you'll be able to implement SSO solutions for your applications. Balancing Security with Easy Usage It was noted that more than 45% of calls to corporate help desks involve user ID or password-related issues. To avoid memorizing multiple logins users put their passwords in insecure locat... (more)

Security for J2EE Applications

Most developers build J2EE applications using their own security mechanism. This causes problems when other applications are introduced, because more logons have to be remembered and users have to physically log on multiple times to use different Web applications. A single sign-on allows a user to logon once and have transparent access to all the applications within a domain. In Part 1 we explain what a single sign-on is and how it works, enabling you to implement a single sign-on solution. In Part 2, we'll implement a single sign-on solution for standalone and Web-based applica... (more)
