摘 要
隨著企業(yè)信息化程度越來(lái)越高，企業(yè)內(nèi)的應(yīng)用系統(tǒng)也越來(lái)越多。但是這些企業(yè)系統(tǒng)的孤立也引發(fā)了大量的問(wèn)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(hù)成本等等。統(tǒng)一用戶管理的目標(biāo)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(shí)現(xiàn)在許多企業(yè)都將已開(kāi)始利用門戶技術(shù)整合應(yīng)用系統(tǒng)，而統(tǒng)一用戶管理系統(tǒng)可以做為門戶的后臺(tái)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(lái)分析了統(tǒng)一用戶管理系統(tǒng)的系統(tǒng)需求，模塊設(shè)計(jì)和系統(tǒng)架構(gòu)。統(tǒng)一用戶管理系統(tǒng)提供了一個(gè)通用的用戶－組織-崗位模型，并為這套模型進(jìn)行了科學(xué)編碼，來(lái)為信息共享，系統(tǒng)交互做好準(zhǔn)備。同時(shí)，統(tǒng)一用戶管理系統(tǒng)也是門戶平臺(tái)的后臺(tái)支持：基于LDAP目錄樹，管理門戶平臺(tái)用戶信息和授權(quán)信息；對(duì)門戶的單點(diǎn)登陸實(shí)現(xiàn)提供支持；管理整合到門戶平臺(tái)的應(yīng)用系統(tǒng)。本文將重點(diǎn)介紹統(tǒng)一用戶管理系統(tǒng)如何管理門戶目錄樹和對(duì)單點(diǎn)登陸提供支持的設(shè)計(jì)。統(tǒng)一用戶管理系統(tǒng)還有一個(gè)作用就是加強(qiáng)了企業(yè)系統(tǒng)管理，在眾多應(yīng)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(wèn)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
