Hello everyone,
I have a problem with the Shield installation when I upgrade to 2.4.0. I follow this link: [https://www.elastic.co/guide/en/shield/current/getting-started.html](https://www.elastic.co/guide/en/shield/current/getting-started.html) but when I submit a request without a username and password, my request is ACCEPTED.
My cluster nodes configuration is:
```
cluster.name: msocESClus
node.name: ${HOSTNAME}
bootstrap.memory_lock: true
network.host: ["172.26.11.31", "127.0.0.1"]
discovery.zen.ping.unicast.hosts: ["msocel01", "msocel02", "msocel03", "msocel04", "msocel05"]
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.multicast.enabled: false
action.auto_create_index: true
index.routing.allocation.enable: all
```
When I check the ES logs, I can find this:
`.... Using [org.elasticsearch.http.netty.NettyHttpServerTransport] as http transport, overridden by [shield] Using [org.elasticsearch.shield.transport.ShieldServerTransportService] as transport service, overridden by [shield] Using [org.elasticsearch.shield.transport.netty.ShieldNettyTransport] as transport, overridden by [shield] .... [WARN][shield.transport] [msocel01] Transport response handler not found of id [229] [WARN][shield.transport] [msocel01] Transport response handler not found of id [387] ....`
This warning are similar to the ticket: [Upgraded from ES2.3.5 to 2.4.0, seeing: Transport response handler not found of id](https://discuss.elastic.co/t/upgraded-from-es2-3-5-to-2-4-0-seeing-transport-response-handler-not-found-of-id/59742)
All the nodes in my cluster have ES 2.4.0 with the last license and shield plugins.
If a remove the _discovery.zen.ping.unicast.hosts: ["msocel01", "msocel02", "msocel03", "msocel04", "msocel05"]_ Shield works correctly but I lost my cluster...
Info: My logstash and beats are down, when I see this logs.
Anybody know what is happening?
Thanks!

Do you have a license installed in the cluster or are you using a trial license? You can check by issuing a GET /\_license and seeing what that returns

Hello Jay,
yes I have, I installed in all the ES nodes. This is the output:
```
curl -XGET 'http://localhost:9200/_license'
{
"license" : {
"status" : "active",
"uid" : "xxxxx",
"type" : "basic",
"issue_date" : "xxxxx",
"issue_date_in_millis" : xxxxx,
"expiry_date" : "xxxxx",
"expiry_date_in_millis" : xxxxx,
"max_nodes" : 100,
"issued_to" : "Sergio",
"issuer" : "Web Form"
}
}
```

The `basic` license does not allow the use of shield. I suggest sending a email to [info@elastic.co](mailto:info@elastic.co) to request an trial license that will allow you to evaluate shield.
