Kibana default basic auth

Hello. I have a basic auth set on the elasticsearch cluster and I would like to set default auth on kibana. On kibana 5.1.2 it was enough to set the elasticsearch.url at : "https://user:passwd@my-elasticsearch-server:9200"
but on kibana 5.4.0 that does not work anymore and kibana require user and password. It is possible to set a default auth on kibana 5.4.0?

@ccrecana this behavior has been changed in 5.2.0, as this wasn't an intentional behavior. There are a few options to do what you're looking for, but first it might help to explain a bit of the background/details of Kibana/Elasticsearch auth.

The way that authentication/authorization works with Elasticsearch via Kibana is two-fold. There is an internal user that Kibana uses to setup the initial .kibana index, the reporting queue, and various administrative features which is controlled by setting elasticsearch.username and elasticsearch.password in the kibana.yml.

However, when the user accesses Kibana they are then forced to authenticate, and this information is "proxied" to Elasticsearch. If you were to install and enable X-Pack Security in Kibana, they'd be prompted with the Login screen at this point and allowed to login. In Kibana 5.1.2, Kibana erroneously passed the username/password on every request if you used a elasticsearch.url like "https://user:passwd@my-elasticsearch-server:9200", which broke this intended behavior. If you wish to emulate this behavior, the closest way to do so is with Option 2 listed below; however, there are some drawbacks to this approach and generally we recommend Option 1.

##Option 1 - Reverse Proxy w/ Basic Auth Header
You can configure Kibana to be behind a reverse proxy that always sets the Baic Auth Headers to a hard-coded user. This way when the user accesses Kibana via the reverse proxy URL, they will get the hard-coded user; however, if you wanted to login as another user you could access Kibana directly and login this way. The following discuss reply illustrates how to do so using NGINX: Auto-authenticating to iframe-embedded Kibana dashboard . This same thing can be accomplished via Apache/HAProxy/etc.

This option works with and without X-Pack Security installed/enabled in Kibana, and provides the ability to access Kibana as an alternate user. However, it does require you to setup/manage a reverse proxy.

##Option 2 - Kibana customHeaders
This solution is very similar to Option 1. Using the elasticsearch.customHeaders setting in the kibana.yml you can pass the same Basic Auth headers to Elasticsearch on every request. However, you'll have to disable X-Pack Security in Kibana for this option to work.

This solution doesn't require a reverse proxy; however, you will be forced to use Kibana as the same user, and disable X-Pack Security.

##Option 3 - Elasticsearch Anonymous Access
Elasticsearch allows you to configure a default user/role(s) when an anonymous user tries to access Elasticsearch itself. How to do so is discussed here. It's possible to essentially set the default user for Kibana using this feature; however, it'll apply to all Elasticsearch access so caution should be taken on which roles/privileges you give this user. This will also require you to disable X-Pack Security in Kibana for this to work.
