Peter Sturge commented on SOLR-1895:
------------------------------------
It's worth bearing in mind that more than just a username is required in the
input in order to ensure secure access. Otherwise, security is compromised
simply by guessing (or already knowing) the username of someone with higher
privileges.
For example:
User Dishwasher has low privileges
User Admin has high privileges
When Dishwasher logs in, all he/she has to do is put Admin's name in the input
argument, and has now assumed Admin's rights.
User Admin doesn't need to be logged in for this to happen.
> LCF SearchComponent plugin for enforcing LCF security at search time

> Key: SOLR-1895
> URL: https://issues.apache.org/jira/browse/SOLR-1895
> Project: Solr
> Issue Type: New Feature
> Components: SearchComponents - other
> Reporter: Karl Wright
> Fix For: 1.5
>
> Attachments: LCFSecurityFilter.java, LCFSecurityFilter.java,
> LCFSecurityFilter.java
>
>
> 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.
