ubuntu在安装LDAP服务器,在windows客户端下查看,并使用java操作LDAP

1.在ubuntu上安装LDAP服务器

sudo apt-get install slapd ldap-utils

输入admin密码: admin

重新配置:

sudo dpkg-reconfigure slapd

Omit OpenLDAP server configuration? No
DNS domain name?

这将会创建基本的目录树结构
理论上是可以随便填的，如果你有域名可以用域名
这里使用 chenjr.cc
Organization name? 也是随便填，这里使用 zju
Administrator password?
Database backend to use? HDB
Remove the database when slapd is purged? No
Move old database? Yes
Allow LDAPv2 protocol? No

2.windows客户端连接服务器

下载LDAP admin软件,打开之后配置连接信息即可

玩玩的就变成这样的:

3.编写代码

打开eclipse:

1、Java客户端API（UnboundID LDAP SDK for Java） 
下载地址 http://sourceforge.net/projects/ldap-sdk/files/ 

2、LDAP客户端（Apache Directory Studio） 
下载地址 http://directory.apache.org/studio/ 

配置一下连接如下:

编写代码开始:

目录结构:

代码如下:
