Hi Lahiru, I had a chance to refresh myself on how this works over the weekend. There are two ways in SolrJ to talk to a Solr protected by basic-auth:
1. The SolrRequest.setBasicAuthCredentials() method I mentioned before. This can be painful though, and isn't even possible in all usecases. 2. Configuring your client process with several System Properties. First, set the property "solr.httpclient.builder.factory" to "org.apache.solr.client.solrj.impl.PreemptiveBasicAuthClientBuilderFactory" to tell SolrJ that you want any SolrClient's setup to use basic-auth. Once that is setup, you can specify your credentials in one of two ways. If you're OK with the auth credentials appearing in the command line for your process, you can set the "basicauth" system property to a value of the form "<username>:<password>". A slightly more approach is to have SolrJ read the credentials from a file. You can choose this approach by setting the "solr.httpclient.config" system property and giving it the full path to an accessible properties file. You then need to create the properties file, specifying your username and password using the "httpBasicAuthUser" and "httpBasicAuthPassword" properties. Currently (2) is not documented in our Solr Ref Guide, though it really should be since it's the most practical way to setup auth. Hope that helps, Jason On Thu, Mar 21, 2019 at 1:25 PM Erick Erickson <erickerick...@gmail.com> wrote: > > One tangent just so you’re aware. You _must_ re-index from scratch.
