Abstract: Provide an electronic-business-to-electronic-business portal that organizes the access to extended business applications. A method allows end users to access a server using standard Web browsers, and then view their own customized menu of applications. Enhanced security and administrative tools allow this portal to be shared throughout enterprises and across supply chains, providing secure access to collaborative applications by business partners and suppliers. Access to specific applications is granted to authorized users and teams, within and outside of a company. Real-time, on-line registration of users allows for rapid changes in teams and projects. Users can be added, deleted, or have access levels altered to reflect changes in the makeup of teams. Provide a common infrastructure for application administration, security management, and directory use, which can help reduce information technology (IT) costs and speed solution deployment.
