一、LDAP概念

LDAP的全称为Lightweight Directory Access Protocol(轻量级目录访问协议), 基于X.500标准, 支持 TCP/IP。

LDAP目录为数据库,通过LDAP服务器(相当于DBMS)处理查询和更新, 以树状的层次结构来存储数据,相对关系型数据库, LDAP主要是优化数据读取的性能,适用于比较少改变、跨平台的信息。

 

二、Softerra LDAP Administrator

         下载安装软件,并配置LDAP

DN:Distinguished Name 唯一标识一条记录的路径,Base DN为基准DN,指定LDAP search的起始DN,即从哪个DN下开始搜索,RDN为叶子结点本身的名字。

DC:Domain Component 一条记录所属区域

OU:Organization Unit 组织单元

CN/UID:一条记录的名字/ID

 

三、在JAVA中应用LDAP

         1、配置文件

         <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">

                   <property name="dataSource" ref="dataSource"/>

         </bean>

         <bean id="ldapcontextSource" class="org.springframework.ldap.core.support.LdapContextSource">

                   <property name="url" value="${LdapConnHost}" /> <!—例: LdapConnHost=ldap://10.190.123.123 -->

                   <property name="userDn" value="${LdapConnUser}" /><!—例: LdapConnUser=cn=root -->

                   <property name="password" value="${LdapConnPwd}" /><!—例: LdapConnPwd=111111 -->

                   <property name="base" value="${LdapBaseDn}" /> <!—Base DN 例: LdapBaseDn=DC=FJTIC -->

                   <property name="pooled" value="false" />

         </bean>
