Question

我对这个领域全新，对java也没有多少经验。我被分配了这个任务，我可以作为管理员和检索信息以简单模式连接，但无法重置密码。我在许多网站上发现我必须使用ssl，但是当我得到一个

时无法成功

＆＃34;简单绑定失败＆＃34;

错误我在下面发布了我的代码以及我注释掉的代码（我之前尝试过）。请帮忙。我无法从我收到的任何来源解决问题。我使用从服务器复制到我的密钥库的证书。这是使用它的正确方法吗？如果我删除了ssl部分

 env.put(Context.SECURITY_PROTOCOL,"ssl");

我得到握手异常

Problem with TLS: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: signature check failed

您的活动目录没有有效证书。

可能是这种情况，因为根证书未在Java中导入。
