Abstract
Single sign-on, or simply SSO, is an emerging technology that is widely popular. It has the ability to log in once, and be authenticated to access all the applications and resources of the organization. With a growth in demand for a variety of e-business applications, they are becoming more and more sophisticated, with complex functional and technical requirements. Although new trends in e-business application development have made the development simple, the issues of integrating the applications with other applications or the existing e-business infrastructure are not trivial. The ideal and efficient solution to address these issues is an effective SSO strategy. Single sign-on is imperative to any organization that has a variety of disparate applications and resources. Organizations implementing single sign-on have realized the benefits, in terms of improved user productivity and simplified administration resulting in reduction of administrative costs. Although, a coherent a single sign-on framework has far reaching benefits, it can be difficult, time-consuming and expensive to retrofit to existing applications. Moreover, with security being non-negotiable, the emphasis on a robust single sign-on strategy has increased.

This white paper describes a single sign-on framework WebIntelligence®. The paper addresses the Integration of an ebusiness application that is built on a tool like WebIntelligence with other applications or the existing e-business infrastructure posing various technical challenges and issues. Although the single sign-on solution discussed in the paper has single signon for WebIntelligence as the central theme, the solution is generic in terms of single sign-on. The paper can serve as a guideline for any SSO implementation. The paper describes the best practices, including the issues and challenges that single sign-on implementation brings to organizations with distributed, diverse applications and technologies.
