Hi all,

Have been stuck for the past day trying to figure out why the spymemcached client(2.11.7) packaged within simple-spring-memcached(3.6.0) is failing to authenticate with the following spymemcached configuration. Upon running the unit test yesterday, it did however spontaneously connect once yesterday but since then has been looping through the same auth failure. I'm positive that the Couchbase server is running and is reachable via the example below which uses class configuration. I'm thinking this has to do with something in my xml config that's flaking, any assistance is much appreciated.

Sample class configuration used to validate connection.

@Bean

@DependsOn("cacheBase")

public CacheFactory cacheFactory() {

CacheFactory cacheFactory = new CacheFactory();

cacheFactory.setCacheName("memcached_bucket_name");

cacheFactory.setCacheClientFactory(new MemcacheClientFactoryImpl());

String server = SERVER;

if (StringUtils.isEmpty(server)) {

server = environment.getProperty("cache.server");

}

SpymemcachedConfiguration cacheConfiguration = createCacheConfiguration(server);

cacheFactory.setAddressProvider(new DefaultAddressProvider(server));

cacheFactory.setConfiguration(cacheConfiguration);

return cacheFactory;

}

private SpymemcachedConfiguration createCacheConfiguration(final String server) {

SpymemcachedConfiguration cacheConfiguration = new SpymemcachedConfiguration();

cacheConfiguration.setConsistentHashing(true);

cacheConfiguration.setUseBinaryProtocol(true);

AuthDescriptor authDescriptor = new AuthDescriptor(new String[]{"PLAIN"}, new PlainCallbackHandler("memcached_bucket_name", "password234243"));

cacheConfiguration.setAuthDescriptor(authDescriptor);

return cacheConfiguration;

}

This is the spring configuration which I'm using that's failing for me.
