Как я аутентифицирован в Redis Cloud Memcached из Spymemcached?

Question

Я пытаюсь подключиться к Redis Cloud Memcached, но получить сообщение об ошибке (ниже). Я проверил, что имя пользователя, пароль, хост и порт верны в интерфейсе apps.redislabs.com. Я могу подключиться, если отключить SASL и подключиться к не прошедшему проверку.

Как я могу диагностировать это?

(Использование spymemcached 2.11.6.)

import net.spy.memcached.auth.*; 
import net.spy.memcached.*; 
... 
List<InetSocketAddress> addresses = Collections.singletonList(addr); 
AuthDescriptor ad = new AuthDescriptor(new String[] { "CRAM-MD5", "PLAIN" }, 
     new PlainCallbackHandler(user, password)); 
MemcachedClient mc = new MemcachedClient(new ConnectionFactoryBuilder() 
     .setProtocol(ConnectionFactoryBuilder.Protocol.BINARY) 
     .setAuthDescriptor(ad).build(), 
AddrUtil.getAddresses(host + ":" + port));

Потерять "CRAM-MD5" в вашей AuthDescriptior декларации.

следующие работы в моих тестах: (пользователь, передать, и URL удалены)

AuthDescriptor ad = new AuthDescriptor(new String[] {"PLAIN"}, new PlainCallbackHandler(user, pass)); 
MemcachedClient mc = null; 
    try { 
     mc = new MemcachedClient(
     new ConnectionFactoryBuilder() 
      .setProtocol(ConnectionFactoryBuilder.Protocol.BINARY) 
      .setAuthDescriptor(ad).build(), 
     AddrUtil.getAddresses(host + ":" + port)); 
    } catch (IOException e) { 
     // handle exception 
    } 
mc.set("foo", 0, "bar"); 
String value = (String) mc.get("foo"); 
System.out.println(value);
