I am trying to set up my DEV cluster it sounded like it would be easier to create the certificates without a password and set the clients to use the certificate and not the full authentication (where the certificate dns must match the machine).

I have worked through many errors with a contractor and still not been able to make this connection. Here is the current error.

```
[2019-01-21T14:50:21,706][ERROR][logstash.licensechecker.licensereader] Unable to retrieve 
license information from license server {:message=>"signed fields invalid"}

```

Is there a specific setting in Logstash.yml to allow it to authenticate based on the certificate and not the full authentication?

Thank you for any help on this difficult and frustrating issue.
