Apache Directory Server使用指南

本教程是在笔者学习JNDI过程中，由于没有合适的免费服务器做为实验，给Sun的JNDI 教程的LDAP服务器使用的又是Sun的服务器，OpenLDAP又没有找到Windows的版本，所以就决定使用Apache的开源LDAP服务器---Apache Directory Server。下面是Apache 网站对Apache Directory Project的介绍：

The Apache Directory Project provides directory solutions entirely written in Java. These include a directory server, which has been certified as LDAP v3 compliant by the Open Group (Apache Directory Server), and Eclipse-based directory tools (Apache Directory Studio).

Apache Directory项目提供了用纯Java编写的目录解决方案，其中包含ApacheDS，即Apache Directory Server，它是一个被授权的LDAP v3的服务器。同时还包含基于Eclipse 的目录工具，即Apache Directory Studio。

ApacheDS基本用户参考指南，主要介绍了如何安装ApacheDS 1.0，通过不同的图形化客户端连接服务器，当然主要还是需要通过JNDI编程来实现服务器的连接，这部分内容在JNDI教程中进行介绍。同时介绍了如何操作目录服务中的数据以及将ApacheDS和其它软件进行集成。

Apache Directory Server简介

ApacheDS 1.0是一个由纯Java语言编写的开源LDAP服务器。ApacheDS具有可嵌入、可扩展、标准的遵守LDAP协议等特性，同时支持其他的网络协议，例如NTP和Kerberos。但是ApacheDS是一个LDAP服务器是最基本的。各个特性介绍如下：

Embeddable means that it is possible to configure, start and stop ApacheDS from other Java components, especially application servers, and the server runs within the same VM. The solution has already been successfully embedded in Apache Geronimo, JBoss, and others. The fact that the server is embeddable is quite interesting, nevertheless you also have the deployment option to run the server standalone, for instance as a Windows service. Perhaps you know this situation from other LDAP servers

open source (like OpenLDAP) as well as commercial ones (like Sun Java System Directory Server). This guide is dedicated to people that are new to ApacheDS. The guide concentrates on installing, configuring and running ApacheDS in a standalone configuration.

Extendable means that the modern architecture of the solution provides many extension points. Write your own partitions to store directory data, interceptors to add functionality,(通过编写自定义分区来存储目录数据，编写自定义拦截器来增加功能。这些都

是通过使用Spring来实现特定的接口来完成的。) etc. by implementing certain interfaces and plugging them in using Spring.

Standard compliant means that ApacheDS 1.0 adheres to all RFCs relevant to LDAPv3. Please note that the server has been successfully certified by the Open Group in September 2006 ("LDAP certified"). Thus LDAP clients may rightly expect that ApacheDS behaves like they expect.

Modern means that ApacheDS aims modernize the LDAP territory, as well as it favors standards compliance. New rich integration tier constructs like LDAP Stored Procedures and Triggers are being built on top of existing standards.

Entirely written in Java means that the software compiles and runs on a huge number of hardware and software platforms. Native installers are available for Windows, MacOS and Solaris (both SPARC and intel platform), but in fact the set of possible targets is by far more extensive.(用Java写的有点就是可移植性好)
