摘 要
隨著企業(yè)信息化程度越來越高，企業(yè)內(nèi)的應用系統(tǒng)也越來越多。但是這些企業(yè)系統(tǒng)的孤立也引發(fā)了大量的問題：信息共享困難，數(shù)據(jù)一致性，安全漏洞，昂貴的人工維護成本等等。統(tǒng)一用戶管理的目標就是要改變以往的松散、孤立的管理方式，創(chuàng)建統(tǒng)一并可重用的用戶管理體系，并且逐步使之成為企業(yè)信息化中重要的基礎(chǔ)性構(gòu)件。同時現(xiàn)在許多企業(yè)都將已開始利用門戶技術(shù)整合應用系統(tǒng)，而統(tǒng)一用戶管理系統(tǒng)可以做為門戶的后臺管理。
本文首先分析了目前企業(yè)信息化建設(shè)現(xiàn)狀，提出統(tǒng)一用戶管理存在的意義。接下來分析了統(tǒng)一用戶管理系統(tǒng)的系統(tǒng)需求，模塊設(shè)計和系統(tǒng)架構(gòu)。統(tǒng)一用戶管理系統(tǒng)提供了一個通用的用戶－組織-崗位模型，并為這套模型進行了科學編碼，來為信息共享，系統(tǒng)交互做好準備。同時，統(tǒng)一用戶管理系統(tǒng)也是門戶平臺的后臺支持：基于LDAP目錄樹，管理門戶平臺用戶信息和授權(quán)信息；對門戶的單點登陸實現(xiàn)提供支持；管理整合到門戶平臺的應用系統(tǒng)。本文將重點介紹統(tǒng)一用戶管理系統(tǒng)如何管理門戶目錄樹和對單點登陸提供支持的設(shè)計。統(tǒng)一用戶管理系統(tǒng)還有一個作用就是加強了企業(yè)系統(tǒng)管理，在眾多應用系統(tǒng)之間架起了一座橋梁，解決了目前系統(tǒng)孤立所引起的許多問題。

Unified user management system and its application in portal
Abstract
As the information level of enterprise is higher, the application of enterprise is getting more and more. But these isolated enterprise systems have also led to a lot of problems: difficulties in sharing information, data consistency, security loopholes, Artificial expensive maintenance costs.Unified user management goal is to change the loose, isolated management, create reusable user management system, and gradually bring it into enterprise basic component. Now while many companies have begun to use portal technology to integrate applications, and unified user management system can serve as a gateway to the management background.
First, this paper analyzes the current information construction status and significance of unified user management exists. Next analysis of a unified user management system of demand, modular design and system architecture. Unified user management system to provide a common user-organization - post model and this model of scientific coding preparing for information sharing, interactive system. Meanwhile, unified user management system is used to manager portal platform : Based on LDAP directory tree, manager portal platform management information and user authorization information; support portal’s SSO; Management Integration Platform gateway to the application. This paper focuses on unified user management system for the management of portal directory tree and single-point landing support design. Unified user management system is also an enhanced role in the enterprise systems management, In many applications served by a bridge to solve the problems caused isolation systems.

Key words:　Portal, Directory tree, SSO, Enterprise information, System isolation
