Hello,

I have been using curator to cleanup my data, for a while now. It worked all well while I was running elasticsearch 5.5.2, but since the upgrade to 6.2.3, it doesn't work. I have also added x-pack with the v6.2.3. Below are the logs from curator. (I'm running everything containerized).

During handling of the above exception, another exception occurred:

Traceback (most recent call last):  
File "/usr/bin/curator\_cli", line 11, in   
load\_entry\_point('elasticsearch-curator==5.4.0', 'console\_scripts', 'curator\_cli')()

Can someone help me here -- How do I authenticate curator with Elasticsearch, as I don't see a location include the elastic credentials on Curator config.

Thanks,  
Sundeep

Curator can and does connect to X-Pack enabled hosts. The options are all in [the documentation](https://www.elastic.co/guide/en/elasticsearch/client/curator/5.5/configfile.html).

A sample configuration is below:

```auto
client:
  hosts: ['myhost_or_ip']
  port: 9200
  use_ssl: true
  certificate: /etc/elasticsearch/certs/ca.crt
  client_cert: /etc/elasticsearch/certs/mynode.crt
  client_key: /etc/elasticsearch/certs/mynode.key
  ssl_no_validate: false
  http_auth: "username:password"

```

- `use_ssl: true` is necessary for SSL-enabled clusters
- `certificate` is necessary if you are using self-signed certs, or ones not recognized by common signing authorities
- `client_cert` and `client_key` are necessary if you are using hostname verification for your SSL.
- `ssl_no_validate: false` means to validate that the certificates are properly signed. If you set this to `true`, you will see warning messages that you are not performing this test.
- `http_auth` needs to be in `"username:password"` format (complete with quotes, if you have special characters in either the username or password). This is quite possibly the source of the error `missing authentication token`. You are not providing a username/password, so no authentication can happen.
