我已经实现了在 AD 中启用、创建和禁用用户的功能。我还需要确保我可以使用 Java 删除 AD 中的用户。 下面是一些相关的代码，谁能告诉我如何删除AD中的用户？ 我更喜欢使用原始 java 代码来实现这一点。

谢谢。

最佳答案

要从上下文中删除用户，您基本上需要使用 javax.naming.Context#unbind 功能。

所以你的方法应该如下所示:

/**
 * Remove the account
 * 
 * @param ctx
 * @param dn
 * @throws NamingException
 */
public static void removeUser(LdapContext ctx, String dn) throws NamingException {
    ctx.unbind(dn); //that's all
}
