Realized The Unification Identity Authentication Research And Application Using Portal And Ldap In The Digital Campus

With the rapid development of Digitalized Campus, various applications are used in Digitalized Campus and the services increase gradually, the drawbacks of the independent authentication have appeared. Therefore, it is an important measure in the information safe system to set up a unified identity system, with which to manage the network users in unison and unifying authentication and authorize.There are many different kinds of servers, platforms of software and hardware, network services, user account etc in Digitalized Campus network system. It is a great challenge to unified manage all of the complicated information. This paper studies the resolution of uniform identity authentication system by the heart of directory service and a simulative environment under Linux has been built. It unifies authentication for different application servers, and implements secure transmission between directory server and other application servers.At first, the paper introduces the LDAP directory protocol is researched all round, and also themodels of the LDAP, the availability of the LDAP directory is analyzed. And then the Kerberos is introduced, particularly the certification process of the Kerberos. The following discussion center on our main jobs based on the design of unified identity authentication of LDAP and implementation of prototype under Linux, From the viewpoint of of network management, it puts forward the principle of design on directory information database and explains the design and implementation about access control and connection pool. With the unified identity authentication system being perfected, it will play an important role among the information safe system of campus network.
