The Design And Implementation Of A Unified Identity Authentication System For A Manufacturing Enterprise's Multi-application System

In recent years,China has proposed a new development strategy,which is named integration of informatization and industrialization,it requires the informationization to drive the industrialization,to promote the informatization of industrialization and to take the new road of industrialization.With the Country's policies and the rapid development of information technology,the information-based business application system is significantly increased,which promotes the product development and productivity of the enterprise.On the one hand,these information-based business application systems have improved the product development and manufacturing efficiency of enterprises;on the other hand,they have put forward more challenges for information system administrators,such as increasement of business application systems,independence of systems,heterogeneous system,isolated islands of information and etc.,these are all obstacles to the development of the integration of informatization and industrialization,which shall be resolved for the development.Focusing on resolve problems of a large manufacturing enterprise as various types of systems,isolated information,and different resources,The research of this thesis combines large manufacturing enterprise work model and the design of process scenarios according to business logic,enterprise application system management and user management,to build up a complete set of unified identity authentication system with assistant of open source or enterprise software.The thesis first analyzes the functional,non-functional and integrative aspects of the system and then sets up logical modules through software,so as to build up a complete system with cooperation between each modules.The units designed and accomplished in this paper mainly include: unified directory,identity management,unified authentication and access control,single sign-on and other modules,and achieve the goal of unified user management by summarizing common processes within the enterprise and the whole life cycle management of user accounts.Based on unifiedidentity authentication system design,three different types of examples as the Portal system,OA system,human resources system with respective representativeness,are proposed in this thesis,to achieve reunification for the source of user,synchronization of user information and application of the system to access single sign-on effect,in order to resolve issues exist in the enterprise,such as inconsistent resources,limited efficiency and etc,reduces the cost of application system management and improves the operation efficiency of the enterprise.
