Is it possible to connect an etcd server without username and password which auth is disable?

Hi

I just want to use jetcd as a client to connect server which auth is disabled and no need to put username and password in the client.
Is it possible to do this? I try but fail with error.

Yes it is possible, please have a look at the test cases
An example of the failing set-up would also be appreciated

Hi
This is the original setup, but this

ClientBuilder builder = Client.builder();

builder.endpoints(config.getEndPoints());
Client client = builder..build();

MemberListResponse memberListResponse = clusterClient.listMember().get();

It failed with previous error.

Is there anything wrong?

The set-up does not seem to be wrong, I've added a test for this case: https://github.com/etcd-io/jetcd/blob/master/jetcd-core/src/test/java/io/etcd/jetcd/ClusterClientTest.java#L54-L65

Maybe you need to check how the etcd server is configured, maybe it requires authentication ?
