I am currently working on SolrCloud and its related security configurations for securing Solr web applications using HTTP Basic Authentication mechanism. Among the Solr nodes inside the SolrCloud clustered env, there seem to be existing some inter-solr-node communication issues due to the security configurations, which are the HTTP Authentication errors. Based on my research, the patch SOLR-4470 (Security for inter-solr-node requests) would be ideal for resolving these issues (please refer to the address: https://wiki.apache.org/solr/SolrSecurity#Security_for_inter-solr-node_requests). However, it seems to me that these security patches are out-of-box additions to the current Solr source codebase, which don't seem to be available in the recent Solr releases.
If someone could point out which Solr releases or the jars from some online repositories that contain this patch, it would be appreciated very much. Jerry This e-mail is confidential.
