Production systems should be secured with Basic Authentication. You can set up Solr Basic Auth directly from the SearchStax Dashboard.
Warning: Service Interruption
Enabling/Disabling this feature restarts your Solr servers, interrupting service for about 30 seconds.
Using /select and /update with Solr Basic Auth
After enabling Solr authentication, your /select and /update interactions with
Solr must include the username and password of a Solr user.
For cURL, add the Solr credentials using the -u 'username:password' parameter.
If your search application doesn’t use cURL, your <Solr HTTP Endpoint> changes
from https://machine... to https://user:password@machine...
If you are trying to use Basic Auth credentials from PowerShell, see Basic Auth Credentials in PowerShell.
Connections to Zookeeper remain unchanged.
