Authentication exception when opening memcached bucket with password from ClientConfiguration

If you try to open a password protected memcached bucket with a configuration containing the password (but only when you call OpenBucket(name) and not OpenBucket(name, password), the client will throw an exception as follows:

System.AggregateException : Could not bootstrap - check inner exceptions for details.

----> Couchbase.Configuration.ConfigException : is this a Memcached bucket?

If you look at the logs you'll find it's really a WebException with a response of unauthorized:
