How xpack.license.self_generated.type: basic setting is really working?

Elastic Stack Elasticsearch
1

Running a demo with ES 6.4.0 i have a strange feeling about how is handled the setting xpack.license.self_generated.type: basic in elasticsearch.yml.

My need is to have SSL (encryption in transit) and no certs authentication beetween nodes or clients.
Reeding the doc i would assume that this is not possible without a valid gold (at least subscription).

But when trying it and setting xpack.license.self_generated.type: basic in order to limit the license to the basic subset it seems that the xpack.ssl.* setup are honored correctly.

ex: openssl s_client -CAfile ./certs/ca.pem -showcerts -connect localhost:9300

SSL handshake has read 1388 bytes and written 194 bytes

or

curl --cacert certs/ca.pem -I https://localhost:9200:

HTTP/1.1 200 OK

Any explanation to what i am missing here ?

In case it can explain something, this is a fresh install on Ubuntu 16.04 on digital ocean from officail ES repos...

Can you post the output of GET /_xpack/license please? Just to make sure that the trial isn't enabled for some reason.

hi @xeraa !

without xpack.license.self_generated.type: basic :

  "license" : {
    "status" : "active",
    "uid" : "d55f8059-6314-49e8-86e8-9d8df79efcb7",
    "type" : "basic",
    "issue_date" : "2018-09-27T16:00:17.880Z",
    "issue_date_in_millis" : 1538064017880,
    "max_nodes" : 1000,
    "issued_to" : "kibana",
    "issuer" : "elasticsearch",
    "start_date_in_millis" : -1
  }
}

with xpack.license.self_generated.type: basic:

{
  "license" : {
    "status" : "active",
    "uid" : "4856423b-09e1-4eac-bd81-6c3257aa6b47",
    "type" : "basic",
    "issue_date" : "2018-09-27T16:08:10.648Z",
    "issue_date_in_millis" : 1538064490648,
    "max_nodes" : 1000,
    "issued_to" : "kibana",
    "issuer" : "elasticsearch",
    "start_date_in_millis" : -1
  }
}

So it seems that this is activated whatever you do ? right ?
