Design And User Control Implementation On Directory Service

Along with the explosively increased information services on Internet, people need to deal with the distributed resources more and more. The quick orientation of these resources and the obtaining of useful information will be a key problem, which need to be solved efficiently.LDAP(Lightweight Directory Access Protocol) offers a standard for users to search and orientate the resources as quickly as they can. Based on the project application, this dissertation is mainly research on the optimisation of the control to realize LDAP directory services for enterprises. Firstly, this dissertation introduces the concepts and the stages of directory services and LDAP directory services and its design. And it also focus on the optimisation of designing of network and the planning of directory services for enterprises. According to the problems of controlling of directory service by application procedure this dissertation offers a 4-layers solution to realize the directory services With analysing the SDK(Software Develop Kit) code, the middle inter-layer is implemented by using of Delphi tool. This middle inter-layer avoids the repeating , time-consuming and low efficiency adjustment procedure between customer-layer and SDK-layer. And it also provides a reusable directory service visit platform. It simplifies the development of directory service by application procedure under Windows environment. The foundation of directory service for the application in enterprises is built up.At last, this dissertation takes a customer management module for university campus network so as to figure out the integration of middle inter-layer and directory service under Windows environment.
