> Support Solr Kerberos Authentication
> ------------------------------------
>
> Key: CONNECTORS-1629
> URL: https://issues.apache.org/jira/browse/CONNECTORS-1629
> Project: ManifoldCF
> Issue Type: Improvement
> Components: Solr 7.x component
> Affects Versions: ManifoldCF 2.14
> Reporter: Jörn Franke
> Assignee: Karl Wright
> Priority: Major
>
> Several enterprise deployments of Solr are leveraging SolrCloud Kerberos
> authentication.
> The integration seems to be rather simple and the goal of this Jira is to
> evaluate the possential needed step to eventually contribute the Kerberos
> integration to the ManifoldCF project.
> The following steps would be needed:
> * One can pass the JVM parameter java.security.auth.login.config to the
> ManifoldCF JVM using -Djava.security.auth.login.config=/path/to/jaas.confg in
> which Kerberos authentication details, such as keytab and principal that has
> the right access to Solr is configured
> * A small adaption to the SolrCloudClient that is used within Manifold needs
> to be done to enable Kerberos authentication:
> HttpClientUtil.setConfigurer(new Krb5HttpClientConfigurer());
> Should this be integrated in Manifold, one may want to consider one input
> field in the configuration in the UI where one can select / flow which user
> defined in the Jaas conf (you can define multiple one) should be chosen. By
> default one may simply select "client" or "SolrJClient" if Jaas.conf is
> present in the System properties. This does not mean the user needs to be
> named like this, but the configuration entry referencing any user should be
> named like this.
> Having a confiugration allows to have a different users per flow. This might
> also be needed in case you have multiple Solr clusters.
