Subject [jira] [Commented] (SOLR-4470) Support for basic http auth in internal solr requests
Date Thu, 21 Feb 2013 11:50:14 GMT


Per Steffensen commented on SOLR-4470:

bq. So let this issue deal with authentication - if you have access then you have access to
all - and make another jira for authorization

Basically yes! The decision on who can be authenticated and to what they can be authorized,
is not the focus of this jira. It is up to the admins of the Solr cluster to setup/program
that. This jira is about what credentials a solr-node will add to the requests it sends itself
to other solr-nodes.

Joggling with authentication/authorization setups is actually more of a matter in the tests
I make in the solr-test-suite, where I want to make a more "normal" kind of setup:
* a search-user that can do searches only
* an update-user that can do updates only
* an admin-user that is allowed to do everything

This cannot be achieved by configuring the web-container. You need to do programmatic authorization.
I will figure out whether I will
* 1) go for the above user/authorization wrt tests
* 2) or if I will make another cut where different users have access to do stuff on different
limited sets of collections
The thing is that a solr-node makes requests to another solr-node in A LOT of different places,
and to make sure it all works I would really not want to make a protection-focused test-suite
that basically tests everything (search, update, collection-creation/deletion, peer-sync,
recovery etc.) again - but just with protection added. I would rather apply protection to
the existing cloud/distributed test-suite (to make pretty sure every kind of solr-to-solr-request
case is covered), and doing that will be much easier with 1) and 2).

> We want to protect any HTTP-resource (url). We want to require credentials no matter
what kind of HTTP-request you make to a Solr-node.
> It can faily easy be acheived as described on
This problem is that Solr-nodes also make "internal" request to other Solr-nodes, and for
it to work credentials need to be provided here also.
> Ideally we would like to "forward" credentials from a particular request to all the "internal"
sub-requests it triggers. E.g. for search and update request.
> But there are also "internal" requests
> * that only indirectly/asynchronously triggered from "outside" requests (e.g. shard creation/deletion/etc
based on calls to the "Collection API")
> * that do not in any way have relation to an "outside" "super"-request (e.g. replica
synching stuff)
> We would like to aim at a solution where "original" credentials are "forwarded" when
a request directly/synchronously trigger a subrequest, and fallback to a configured "internal
credentials" for the asynchronous/non-rooted requests.
> In our solution we would aim at only supporting basic http auth, but we would like to
make a "framework" around it, so that not to much refactoring is needed if you later want
to make support for other kinds of auth (e.g. digest)
> We will work at a solution but create this JIRA issue early in order to get input/comments
from the community as early as possible.
