修改属性
验证密码

[一]、概述

jldap 官网：http://www.openldap.org/jldap/

可以从官网下载源编译生成jar包，如果项目是用maven构建的，在pom.xml中增加如下内容即可：

    <dependency>

     <groupId>com.novell.ldap</groupId>

     <artifactId>jldap</artifactId>

     <version>4.3</version>

     <type>jar</type>

     <scope>compile</scope>

    </dependency>

[二]、基本操作

为了演示基本的操作，需要搭建个LDAP服务，有关openLDAP在windows上的安装配置可参见：http://www.micmiu.com/enterprise-app/sso/openldap-windows-config/ ，我配置好演示用的LDAP基本信息可见客户端截图：

1.查询
