Subject [jira] Updated: (SOLR-1895) LCF SearchComponent plugin for enforcing LCF security at search time
Date Thu, 29 Apr 2010 00:17:49 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1895?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karl Wright updated SOLR-1895:
------------------------------

    Attachment: LCFSecurityFilter.java

Updated version, using getFilters() and setFilters(), which seems resilient about where it
is placed in the execution chain.

> I've written an LCF SearchComponent which filters returned results based on access tokens
provided by LCF's authority service.  The component requires you to configure the appropriate
authority service URL base, e.g.:
>   <!-- LCF document security enforcement component -->
>   <searchComponent name="lcfSecurity" class="LCFSecurityFilter">
>     <str name="AuthorityServiceBaseURL">http://localhost:8080/lcf-authority-service</str>
>   </searchComponent>
> Also required are the following schema.xml additions:
>    <!-- Security fields -->
>    <field name="allow_token_document" type="string" indexed="true" stored="false"
multiValued="true"/>
>    <field name="deny_token_document" type="string" indexed="true" stored="false" multiValued="true"/>
>    <field name="allow_token_share" type="string" indexed="true" stored="false" multiValued="true"/>
>    <field name="deny_token_share" type="string" indexed="true" stored="false" multiValued="true"/>
> Finally, to tie it into the standard request handler, it seems to need to run last:
>   <requestHandler name="standard" class="solr.SearchHandler" default="true">
>     <arr name="last-components">
>       <str>lcfSecurity</str>
>     </arr>
> ...
> I have not set a package for this code.  Nor have I been able to get it reviewed by someone
as conversant with Solr as I would prefer.  It is my hope, however, that this module will
become part of the standard Solr 1.5 suite of search components, since that would tie it in
with LCF nicely.
