| The network technology is developped rapidly nowdays, under such backgrand, the campus information technology is developing very fast. The improvement of various campus systems provides the platform for the students and the teaching staff to quickly access of knowledge and to enhance the learning efficiency. However, due to the different system achitechture and different system setup time during campus network construction, each application system has their own user management system, which results in not only cannot users’information be exchanged, but also an ineffective way to management. Thus the teaching staff and students are required to enter login account and password according to the system they are using. The massive login accounts and passwords may be forgotten and confusion. Meanwhile, the administrator must maintain great number of users information in different system, in order to ensure the consistency of the data and the users of the system. An error will be increased accordingly, security will also be reduced when the number of user is increasing. For this reason, achieving a unified, efficient, stable, and secure and Unified Authentication platform has become a important issues in campus networking construction. Campus Network Unified Authentication system is to resolve user login issues, network management, information security issues, as well as how to structure application system problems in communication.This thesis based on the research and implement of LDAP WebServices unified authentication system, combined with campus web application environment, establish Shaanxi vocational and technical college campus unified identity certification system. The mainly technologies used in this thesis are including text application with LDAP Lightweight Directory Access Protocol, a single sign-on technology, Webservices technology, and so on. First Unified Identity of development internal and external is explored. Secondly discussed the identity relevant points; At last established the unified authentication system of campus network based on Java platform with the theoretical knowledge guidance, In the authentication system, the user information are recorded in LDAP server. The authencation system is designed and developed in J 2 EE architechture and use some popular development techniques, such as spring, sturts 2, hibernate, as part of the Unified Authentication Center portal. The portal interact with all application systems by webservices interface and achieve a unified authentication single sign-on feature, you can log in to all of the authorized the application only by one indetification.Finally, the system is tested and the LDAP server security and webservice interface of the Security are improved in order to ensure that Shaanxi technical college campus unified identity certification system is safe and effective for the teachers and students.The main work is the research and implement of unified authentication system based on the LDAP and webServices. Leveraging the system, the decentralization of the user information in campus network is able to be centralized effectively. Thereby improve the campus network management level, as well as the efficiency. |
