Subject [jira] [Commented] (SOLR-4470) Support for basic http auth in internal solr requests
Date Mon, 18 Feb 2013 15:39:13 GMT


Per Steffensen commented on SOLR-4470:

bq. It does seem kind of annoying to have to configure it for every core rather than per node.

It can be done per node in solr.xml or using VM-params. But it is actually also annoying to
have to do it for every node, if you have a lot of them in your cluster. It really should
be the same credentials across all nodes in the same cluster, so a cluster-global config would
be the best - like e.g. in ZK.

Until we get closer to an agreement on how it can be done I will create a way to specify it
in solr.xml or through VM-params. Like e.g. zkHost. This might also end up being the end solution
for this ticket and then future tickets might want to improve on the solution.

> 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.

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.
