Subject [jira] [Commented] (SOLR-4470) Support for basic http auth in internal solr requests
Date Sat, 23 Feb 2013 10:58:14 GMT


Per Steffensen commented on SOLR-4470:

Well I developed first and foremost to be used internally by my organization, so I developed
on top of an internal 4.0.0+ version (the + being modifications we have not gotten committed
yet - it is hard to get cool stuff committed if it involves a lot of changes - SOLR-3178).
You will probably not be able to use a patch made from there. Therefore I need to move changes
to a clean Apache revision/branch anyway, and that is where you could have some influence
on the choice. I will go for 4.x branch.

I would like to introduce a few new sayings
* Patches in Jira fitting on top for recent revisions are better than patches in Jira fitting
on top of old revisions - commit it while its hot
* Projects where you trust your test-suite enough to dare do major refactoring, are the only
projects you can keep building on for a long time

> 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.
