java - 忽略证书时出现 CertificateException

Question

我正在尝试 LDAPS 身份验证，但我忽略了 SSL 证书。

public class BlindSSLSocketFactoryTest extends SocketFactory {

    private static SocketFactory blindFactory = null;

    static {
        TrustManager[] blindTrustMan = new TrustManager[]{new X509TrustManager() {
            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }

            public void checkClientTrusted(X509Certificate[] c, String a) {
            }

            public void checkServerTrusted(X509Certificate[] c, String a) {
            }
        }};

        try {
            SSLContext sc = SSLContext.getInstance("SSL");
            sc.init(null, blindTrustMan, new java.security.SecureRandom());
            blindFactory = sc.getSocketFactory();
        } catch (GeneralSecurityException e) {
            e.printStackTrace();
        }
    }

    public static SocketFactory getDefault() {
        return new BlindSSLSocketFactoryTest();
    }

    public Socket createSocket(String arg0, int arg1) throws IOException,
            UnknownHostException {
        return blindFactory.createSocket(arg0, arg1);
    }

    public Socket createSocket(InetAddress arg0, int arg1) throws IOException {
        return blindFactory.createSocket(arg0, arg1);
    }

    public Socket createSocket(String arg0, int arg1, InetAddress arg2, int arg3)
            throws IOException, UnknownHostException {
        return blindFactory.createSocket(arg0, arg1, arg2, arg3);
    }

    public Socket createSocket(InetAddress arg0, int arg1, InetAddress arg2,
            int arg3) throws IOException {
        return blindFactory.createSocket(arg0, arg1, arg2, arg3);
    }
}

还有

        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY,
                "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, LDAP_SERVER);

        env.put("java.naming.ldap.factory.socket", BlindSSLSocketFactoryTest.class.getName());

在开发 PC 上运行时，它按预期工作:证书被忽略，身份验证成功。

在带有 OpenJDK 的 ARM 设备上运行时，我得到

这是为什么？我怎样才能让设备像电脑一样运行？

请不要评论“您应该改为修复证书”，谢谢。

我需要禁用端点识别

-Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true
