JAVA查询 LDAP 数据 （Java query data from LDAP server）

 刚刚完成的代码，不敢独享。

 

花了3天时间研究LDAP+ JAVA LDAP.

 

测试环境： OpenLdap -- test server

                WIN XP 系统

 

首先把 LDIF 文件给粘贴出来

 

Init.ldif

dn: dc=perficient,dc=com objectClass: top objectClass: dcObject objectClass: organization dc: perficient o: perficient.com description: perficient.com ldap dn: cn=Manager,dc=perficient,dc=com objectClass: organizationalRole cn: Manager description: Directory Manager dn: ou=Individual,dc=perficient,dc=com ou: Individual objectClass: organizationalUnit dn: ou=Manager,dc=perficient,dc=com ou: Manager objectClass: or

 

User.ldif

 

dn: uid=HE199,ou=Individual,dc=perficient,dc=com uid: HE199 cn: Prince Zhang sn: Prince userPassword: 123456 objectClass: inetOrgPerson dn: uid=HE178,ou=Individual,dc=perficient,dc=com uid: HE178 cn: Jensen Zhu sn: Jensen userPassword: 123456 objectClass: inetOrgPerson dn: uid=HE001,ou=Manager,dc=perficient,dc=com uid: HE001 cn: Peter Liu sn: Peter userPassword: 123456 objectClass: inetOrgPerson

 

Java 连接以及 查询代码

输出数据：

 

Authentication Successful
The Password:[B@1ffb8dc|[B@1c184f4|[B@1ffbd68
