Question

我正在唱Java并且要更改AD中的密码。我已将证书导入服务器，但证书中出现错误。

导入有效：

keytool -import -keystore "C:\Program Files\Java\jre6\lib\security\cacerts" -trustcacerts -alias openldap -file "C:\certnew.cer"

列表有效：

keytool -list -keystore "C:\Program Files\Java\jre6\lib\security\cacerts"

我的代码：

public class PassChange
{
    public static void main (String[] args) {

    Hashtable env = new Hashtable();
    String userName = "CN=optimus,DC=ad,DC=euclid,DC=com";

    String oldPassword = "euclid!23";
    String newPassword = "kcube!23";

    //Could also do this via command line java -Djavax.net.ssl.trustStore....

    String keystore = "C:\\Program Files\\Java\\jre6\\lib\\security\\cacerts";

    // 1    String keystore = "C:\\Program Files\\Java\\jre6\\lib\\security\\cacerts";
    // 2    String keystore = "C:\\Program Files\\Java\\jre6\\lib\\security\\cacerts.jks";
    // 3    String keystore = "c:\\";
    // 1,2,3 all error

    System.setProperty("javax.net.ssl.trustStore", keystore);

    env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
    //set security credentials, note using simple cleartext authentication
    env.put(Context.SECURITY_AUTHENTICATION,"simple");
    env.put(Context.SECURITY_PRINCIPAL,userName);
    env.put(Context.SECURITY_CREDENTIALS,oldPassword);

    //specify use of ssl
    env.put(Context.SECURITY_PROTOCOL,"ssl");

    //connect to my domain controller
    String ldapURL = "ldaps://xxx.xxx.xxx.xxx:636";
    env.put(Context.PROVIDER_URL,ldapURL);

    try {

        // Create the initial directory context
        LdapContext ctx = new InitialLdapContext(env,null);

        //change password is a single ldap modify operation
        //that deletes the old password and adds the new password
        ModificationItem[] mods = new ModificationItem[2];
        String oldQuotedPassword = "\"" + oldPassword + "\"";
        byte[] oldUnicodePassword = oldQuotedPassword.getBytes("UTF-16LE");
        String newQuotedPassword = "\"" + newPassword + "\"";
        byte[] newUnicodePassword = newQuotedPassword.getBytes("UTF-16LE");

        mods[0] = new ModificationItem(DirContext.REMOVE_ATTRIBUTE, new BasicAttribute("unicodePwd", oldUnicodePassword));
        mods[1] = new ModificationItem(DirContext.ADD_ATTRIBUTE, new BasicAttribute("unicodePwd", newUnicodePassword));

        ctx.modifyAttributes(userName, mods);

        System.out.println("Changed Password for: " + userName);    
        ctx.close();

    } 
    catch (NamingException e) {
        System.err.println("Problem changing password: " + e);
    }
    catch (UnsupportedEncodingException e) {
        System.err.println("Problem encoding password: " + e);
    }
}
}

错误讯息：

问题更改密码：javax.naming.CommunicationException：simple bind failed：xxx.xxx.xxx.xxx：636 [根异常是javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到所请求目标的有效证书路径]

Answer 1

您导入了哪个证书？您不需要服务器证书。相反，您需要证书颁发机构的公钥。具体而言，交换机-trustcacerts旨在表明这是CA公钥。

通过名称猜测，我想知道你是否抓住了服务器的证书。

ssl证书到AD密码更改
