Hi. Is it possible to enable Basic Auth on ES without SSL? I couldn't find that info.  
We're configuring SSL at the edge of our cluster and enabling SSL beyond that between services is not a requirement for us.

Not sure, those are a mandatory boostrap checks when starting your cluster  
if security is enabled then you must have SSL/TLS, except if your cluster is a single node 🙂  
check it [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks-xpack.html#bootstrap-checks-tls)

You are required to have SSL between nodes (the `transport` port that defaults to 9300).  
You can use the `elasticsearch-certutil` tool to set that up with a cluster-specific CA, with very minimal effort or impact on your cluster.

You are not required to configure SSL for the REST interface (the `http` port that defaults to 9200).
