------------------------------------
Summary: 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
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.
