I am moving from client-side (my personal local host environment; Linux) to Solr running as a standalone backend server on a cloud VPS.
The web domain (mine) is SSL-only, and Solr is SSL-enabled with a signed (Let's Encrypt) certificate. My domain index.html page includes a search interface (input element) to Solr. I am largely unfamiliar with deployment of Solr to the web. SSL etc. is enabled in "solr.in.sh", as is Basic Authentication. "security.json" is present in "$SOLR_HOME". Access to the Admin UI is password-protected (my Solr administrator username, password) with "admin" role / privileges in Solr. I want to allow anonymous (i.e. any) users to be able search the site; however they are being required to log in to Solr. How do I enable this - either in the Admin UI Security pane, or manually-editing "security.json"?
