First try to enable user authentication for different Elasticsearch indices

KibanaUserAuth.md

You need to point the kibana config.js to this vHost with the correct port!
In this case
```
$ grep elas config.js
elasticsearch: "http://elasticsearch",
```

Then have ES only listen on localhost, so that everyone need to go though this
Host:

```
<VirtualHost <%= ipaddress %>:80>
  ServerName elasticsearch
  ServerAdmin root@localhost

  <LocationMatch "/[^/]*foobar[^/]*/">
    AuthType Basic
    AuthName elasticsearch
    AuthBasicProvider ldap
    AuthLDAPURL ldaps://<%= ldap_stuff %>?uid?sub?(objectClass=person)
    AuthzLDAPAuthoritative on
    AuthLDAPGroupAttributeIsDN on
    AuthLDAPGroupAttribute uniquemember
    AuthLDAPCompareDNOnServer off
    AuthLDAPBindDN <%= ldap_bindn %>
    AuthLDAPBindPassword <%= ldap_password %>
    Require valid-user
  </LocationMatch>

  ProxyPass / http://localhost:9200/
  ProxyPassReverse / http://localhost:9200/

  LogLevel debug
  CustomLog ${APACHE_LOG_DIR}/elasticsearch-access.log combined
  ErrorLog ${APACHE_LOG_DIR}/elasticsearch-error.log
</VirtualHost>

# vim: ft=apache syn=apache ts=2 sw=2
```

Doesn't work for me.
Kibana's Javascript tries to query the protected indices and fails to pop up any password prompt for the user and just gives up.
