Question

我正在连接到LDAP，这工作正常。但是，我需要更改一个属性的值。我能够读取当前值，但我无法修改该值。这是我的代码：

我在互联网上尝试过很多东西，但都是因为一个错误：

  [Root exception is java.net.ConnectException: Connection refused: connect] (It's always in the "executing" line of code).

这就是我试过的 - 我做错了什么？请给我一些建议。

 Attribute mod0 = new BasicAttribute("attribute", "AAA");
 mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, mod0); 
 authContext.modifyAttributes("correctDn", mods);

后来，我尝试了这个：

 Attribute acl = new BasicAttribute( "attribute", "asdf");
 authContext.modify( entryDN, new LDAPModification(LDAPModification.ADD, acl));

已编辑这是在处理推荐时拒绝连接。您正在与已向您发送到主服务器的LDAP从服务器进行通信，并且您无法连接到主服务器，因为从服务器配置已向您提供错误的引用信息或者因为存在防火墙主LDAP服务器。

连接拒绝LDAP（Java）
