JAVA修改AD域密码_免证书认证

更改用户账户密码，必须要使用ssl方式登录到AD。

网上大部分教程使用TrustStore的方式连接， 

        Hashtable env = new Hashtable();
        System.setProperty("javax.net.ssl.trustStore", KEYSTORE);
        System.setProperty("javax.net.ssl.trustStorePassword", KEYSTORE_PWD);
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, ADMIN_NAME);
        env.put(Context.SECURITY_CREDENTIALS, ADMIN_PASSWORD);
        env.put(Context.SECURITY_PROTOCOL, "ssl");
        env.put(Context.PROVIDER_URL, LDAP_SSL_URL);
try {
            ctx =  new InitialLdapContext(env, null);//new InitialDirContext(HashEnv);// 初始化上下文
        } catch (AuthenticationException e) {
            System.out.println("身份验证失败!"+e.toString());
            e.printStackTrace();
        } catch (CommunicationException e) {
            System.out.println("AD域连接失败!"+e.toString());
            e.printStackTrace();
        } catch (Exception e) {
            System.out.println("身份验证未知异常!"+e.toString());
            e.printStackTrace();
        } finally{
            return ctx;
        }

最后ssl连接失败，报如下错误：javax.naming.CommunicationException: simple bind failed: xxxx:636 [Root exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target]。

也有部分教程提到了绕过ssl的方式，但是都只有部分代码，直到遇到了这段代码

重要备注：虽然该方式可以避免使用TrustStore认证的方式，但是ad域控服务器仍然需要添加信任证书，如下

 且该证书对应的域名必须和AD域控所管理的域保持一致（也可能是AD域对应的证书服务器颁发的证书，我们的域控恰好是对应的证书服务器），域控处于dccn.com, 则证书不能使用例如abc.test.com,否则会报DNS异常如下：

javax.naming.CommunicationException: simple bind failed: cdt.xxx.cn:636 [Root exception is javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative DNS name matching cdstest.huanghongbo.cn found.]
