Hi, I'm facing this issue where SolrJ calls are randomly failing on basic authentication. Here's exception:
ERROR923629[qtp466002798-20] - org.apache.solr.security.PKIAuthenticationPlugin.doAuthenticate(PKIAuthenticationPlugin.java:125) - Invalid key INFO923630[qtp466002798-20] - org.apache.solr.security.RuleBasedAuthorizationPlugin.checkPathPerm(RuleBasedAuthorizationPlugin.java:144) - request has come without principal. failed permission org.apache.solr.security.RuleBasedAuthorizationPlugin$Permission@1a343033 INFO923630[qtp466002798-20] - org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:429) - USER_REQUIRED auth header null context : userPrincipal: [null] type: [READ], collections: [knowledge,], Path: [/select] path : /select params :df=text&distrib=false&qt=/select&preferLocalShards=false&fl=id&fl=score&shards.purpose=4&start=0&fsv=true&shard.url= http://xx.xxx.x.222:8983/solr/knowledge/|http://xx.xxx.xxx.246:8983/solr/knowledge/&rows=3&version=2&q=*:*&NOW=1463512962899&isShard=true&wt=javabin Here's my security.json. I've protected "browse" and "select" request handler for my queries. { "authentication": { "blockUnknown": false, "class": "solr.BasicAuthPlugin", "credentials": { "solr": "IV0EHq1OnNrj6gvRCwvFwTrZ1+z1oBbnQdiVC3otuq0= Ndd7LKvVBAaZIF0QAVi1ekCfAJXr1GGfLtRUXhgrF8c=" } }, "authorization": { "class": "solr.RuleBasedAuthorizationPlugin", "user-role": { "solr": "admin", "solradmin": "admin", "beehive": "dev", "readuser": "read" }, "permissions": [ { "name": "security-edit", "role": "admin" }, { "name": "browse", "collection": "knowledge", "path": "/browse", "role": [ "admin", "dev", "read" ] }, { "name": "select", "collection": "knowledge", "path": "/select", "role": [ "admin", "dev", "read" ] }, { "name": "admin-ui", "path": "/", "role": [ "admin", "dev" ] }, { "name": "update", "role": [ "admin", "dev" ] }, { "name": "collection-admin-edit", "role": [ "admin" ] }, { "name": "schema-edit", "role": [ "admin" ] }, { "name": "config-edit", "role": [ "admin" ] } ] } } Here's my sample code: SolrClient client = new CloudSolrClient("zoohost1:2181,zoohost2:2181,zoohost3:2181"); ((CloudSolrClient)client).setDefaultCollection(DEFAULT_COLLECTION); ModifiableSolrParams param = getSearchSolrQuery(); SolrRequest<?> solrRequest = new QueryRequest(param); solrRequest.setBasicAuthCredentials(USER, PASSWORD); try{ for(int j=0;j<20;j++){ NamedList<Object> results = client.request(solrRequest); } }catch(Exception ex){ } private static ModifiableSolrParams getSearchSolrQuery() { ModifiableSolrParams solrParams = new ModifiableSolrParams(); solrParams.set("q", "*:*"); solrParams.set("qt","/select"); solrParams.set("rows", "3"); return solrParams; } The query sometime returns results, but fails probably half of the time, there's no pattern though. This is applicable to any request handler specified in the security.json Looks like the SolrRequest loses the user/password on the flight. Here's the exception recieved at SolrJ client: org.apache.solr.common.SolrException.log(SolrException.java:148) - org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://xx.xxx.xxx.134:8983/solr/knowledge: Expected mime type application/octet-stream but got text/html. <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <title>Error 401 Unauthorized request, Response code: 401</title> </head> <body><h2>HTTP ERROR 401</h2> <p>Problem accessing /solr/knowledge/select.

I'll really appreciate if someone can let me know what I'm missing here.
