No need to shut down servers. Do the configuration change in security.json. Done. What is the remaining question here?
Jan, it was Related to Kerberos Authentication that we were discussing, as in docs we have seen to restart solr instances under security.json section. Shawn, If trying authentication when Solr is NOT in cloud mode, that probably does require a restart, because when Solr is not in cloud mode, it is far less dynamic. Thanks for confirmation Shawn!
