I'm trying LDAPS authentication, but I'm ignoring the SSL certificate.
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);
}
}
Also
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());
When running on the development PC, it works as expected: certificate ignored, and authentication successful.
When running on an ARM device with OpenJDK, instead I get

Why is that and how can I make the device behave like the pc?
Please refrain to comment "you should fix the certificate instead", thanks.
