使用 java JNDI 更新信息活动目录数据？

Question

我想使用 java JNDI 来更新/插入 Active Directory 中可用或不可用的用户信息。我创建了一个允许 Active Directory 用户获取他们的信息的应用程序，并且我能够从 Active Directory 中提取数据，但我不知道如何使用用户想要更新的 jndi Java 将数据保存在 Active Directory 中.

Answer 1

ctx.modifyAttributes(unique_name,iteam); 

使用此方法您可以更新活动目录中的记录。 name 表示 searchbase 和 search filter 的组合，使数据在 ldap 活动目录中唯一。

ModificationItem[] iteam = new ModificationItem[number_of_attribute_you_want_to_update];

iteam 是您要进行的更改的数组。

Attribute name = new BasicAttribute("displayName",userDetail.getName());
// replacing the value
    item[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, name);

设置值
