Peter Sturge commented on SOLR-1895:
------------------------------------

The usual way is to configure the application server running solr to either use
certificate authentication (which requires the connecting client to be able to
identify themselves via a secure cert)
{quote}
Yes, cert authentication is a good way to go, but once you've got one (because
you have at least some privileges), you can by bypass the lower-layer doc
security because you've already done the cert auth.
{quote}
configure the application server to not accept connections from (say) anything
other than the localhost adapter.
{quote}
I don't understand how localhost-only would give you any access off the box.
I guess what I meant was, your client is wherever your client is, and this
client could (and probably would) have a web browser installed. If a bona-fide
user was an IT Operator, it would be easy for him/her to 'pretend' to be an HR
Manager, unless some kind of post-login identity check prevents it.
One way 'round this is to encrypt part or all of the http parameters
(essentially, this is what the hash mechanism does in SOLR-1872).
> 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.
