> 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.
