想删除ldap节点并删除它下面的所有子树节点

Question

我想删除ldap节点并删除它下面的所有子树节点。 例如，我想删除 ou=F115630019 及其子节点，即快照中显示的 cn =xxxxx 和 ou=115630019。

在运行以下代码时，我遇到了以下错误。请告诉我如何解决此问题。

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -1
    at java.lang.String.substring(String.java:1911)
    at deleteorg.deleteDN(deleteorg.java:28)

只有叶节点可以从 ldap 中删除。您需要按照以下步骤操作。

1. 遍历subtre，找到最后一个元素
2. 以相反的顺序删除此节点并向上移动直到到达目标/突出显示的节点
