After upgrading an elasticsearch 2 instance to 5.6.9 I got an error "missing authentication token for REST request". I fixed that by setting "xpack.security.enabled: false". However, I'm also sucessfully running an elasticsearch 5.3 cluster where I didn't need that setting and still can perform any…

Default behavior of xpack.security.enabled

With both I'm simply using the docker image, no extra license (guess that means "Basic").
