> Support Secure Impersonation / Proxy User for solr authentication
> -----------------------------------------------------------------
>
> Key: SOLR-9324
> URL: https://issues.apache.org/jira/browse/SOLR-9324
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Reporter: Gregory Chanan
> Assignee: Gregory Chanan
> Attachments: SOLR-9324-tests.patch, SOLR-9324.patch, SOLR-9324.patch,

>
>
> Solr should support Proxy User / Secure Impersonation for authentication, as
> supported by hadoop
> (http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Superusers.html)
> and supported by the hadoop AuthenticationFilter (which we use for the
> KerberosPlugin).
> There are a number of use cases, but a common one is this:
> There is a front end for searches (say, Hue http://gethue.com/) that supports
> its own login mechanisms. If the cluster uses kerberos for authentication,
> hue must have kerberos credentials for each user, which is a pain to manage.
> Instead, hue can be allowed to impersonate known users from known machines so
> it only needs its own kerberos credentials.
