我正在尝试使用spring ldap 1.3.1.RELEASE连接到windows server 2008上的ldap 活动目录 ，ldap 配置如下：

  • ldap 网址是：ldap://dc.fabrikam.com
  • 用户名：管理员
  • 密码：123456

- spring ldap配置如下：

    <bean id="contextSource" 
    class="org.springframework.ldap.core.support.LdapContextSource">
    <property name="url" value="ldap://dc.fabrikam.com" />
    <property name="base" value="dc=fabrikam,dc=com" />     
    <property name="userDn" value="CN=administrator,CN=Users,DC=fabrikam,DC=com" />     
    <property name="password" value="123456" />


    <property name="baseEnvironmentProperties">
    <map>
        <entry key="java.naming.referral">
            <value>follow</value>
        </entry>
    </map>
    </property>

</bean>

<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
    <constructor-arg ref="contextSource" />
</bean>

  • LDAPContactDAO：

    @Service
public class LDAPContactDAO implements ContactDAO {

@Autowired
private LdapTemplate ldapTemplate;

public List getAllContactNames() {
    return ldapTemplate.search("", "(objectclass=person)",
            new AttributesMapper() {
                public Object mapFromAttributes(Attributes attrs)
                        throws NamingException {
                    return attrs.get("cn").get();
                }
            });
}

}

- 异常前的调试：

请指教。

更新：

我设法使用以下配置使用jxplorer连接到活动目录：

  1. 主持人： dc.fabrikam.com
  2. 端口： 389
  3. 基础 DN： dc=fabrikam,dc=com
  4. 用户 DN： CN=administrator,CN=Users,DC=fabrikam,DC=com
  5. 密码：秘密

但我仍然通过spring ldap连接超时。

更新2：

现在问题已缩小到 spring ldap，因为我尝试使用 JNDI 进行上述配置，并且与 ldap 的连接工作正常，如此处所述：

ldap 搜索很慢

我认为推荐属性可能是问题所在。

我们发现此问题是由于 DNS 中不存在域控制器造成的。如果您使用的是域名而不是 IP，请执行 NSLOOKUP 以显示该域指向的所有 IP：

NSLOOKUP fabrikam.com

确保来自 NSLOOKUP 的所有 IP 在端口 389 上都可以访问：

Test-NetConnection 172.30.2.1 -port 389

连接到远程资源时，可能会出现一千件事。要缩小原因范围，请执行以下操作：

  • 检查 Windows 日志（使用事件查看器）
  • 如果启用，请禁用 dc.fabrikam.com 上的 Windows 防火墙（然后确保端口 389 已打开）
  • 尝试从您手动运行 Java 应用程序的主机连接到 LDAP，例如telnet dc.fabrikam.com 389
  • 如果可能的话，将您的 Java 应用程序部署在同一主机 dc.fabrikam.com 上以排除连接问题

要解决这个问题，您需要在您的计算机上添加一个LDAP DNS 配置，以允许与 LDAP 服务器建立弹簧 连接。

  • Linux：/etc/hosts

  • Windows：C:\Windows\System32\drivers\etc\hosts

打开 cmd使用NSLOOKUP命令查看LDAP地址，然后将 ldap 服务器地址添加到 windows hosts 文件中：<server IP> <server host name>

例子：

192.168.1.123 ldap.atlassian.com

您遇到的问题是您只需将这些 aumetnar 渗入基础的连接进行分组，例如您的配置是：

<property name="base" value="dc=fabrikam,dc=com" />

改成：

<property name="base" value="ou=grupo,dc=fabrikam,dc=com" />
