摘 要
随着企业信息化程度越来越高，企业内的应用系统也越来越多。但是这些企业系统的孤立也引发了大量的问题：信息共享困难，数据一致性，安全漏洞，昂贵的人工维护成本等等。统一用户管理的目标就是要改变以往的松散、孤立的管理方式，创建统一并可重用的用户管理体系，并且逐步使之成为企业信息化中重要的基础性构件。同时现在许多企业都将已开始利用门户技术整合应用系统，而统一用户管理系统可以做为门户的后台管理。
本文首先分析了目前企业信息化建设现状，提出统一用户管理存在的意义。接下来分析了统一用户管理系统的系统需求，模块设计和系统架构。统一用户管理系统提供了一个通用的用户－组织-岗位模型，并为这套模型进行了科学编码，来为信息共享，系统交互做好准备。同时，统一用户管理系统也是门户平台的后台支持：基于LDAP目录树，管理门户平台用户信息和授权信息；对门户的单点登陆实现提供支持；管理整合到门户平台的应用系统。本文将重点介绍统一用户管理系统如何管理门户目录树和对单点登陆提供支持的设计。统一用户管理系统还有一个作用就是加强了企业系统管理，在众多应用系统之间架起了一座桥梁，解决了目前系统孤立所引起的许多问题。

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
