{quote}Thanks for sharing the process details, I'll keep that in mind for
future reference. Is there an official page with the process?

{quote}There should be no need to handle a per implementation handling in
security framework. If we go down this rabbit hole, this is going to be a
nightmare. if we implement a solution, it should be universal to all
authorization providers.

Yes I didn't upload the patch with the intent of committing. This is just a
reference to show how this has been solved with Hadoop auth plugin. I see two
options being discussed here,
(a) Forward the original request as is (i.e. to keep all the original HTTP
headers intact etc.).
(b) Change the behaviour of Solr request forwarding logic to return 302
response
With option (a) we will be implementing a generalised version of "proxy users"
functionality in Hadoop. With option (b) we will be making a backwards
incompatible change in the Solr behaviour since solrj is not the only client
that talks to Solr. So we should exercise some caution with option (b).

> Solr serves client requests going throught 3 steps - init(), authorize() and
> handle-request ([link
> git-link|https://github.com/apache/lucene-solr/blob/releases/lucene-solr/7.3.1/solr/core/src/java/org/apache/solr/servlet/HttpSolrCall.java#L471]).
> init() initializes all required information to be used by authorize().
> init() skips initializing if request is to be served remotely, which leads to
> skipping authorization step ([link
> git-link|https://github.com/apache/lucene-solr/blob/releases/lucene-solr/7.3.1/solr/core/src/java/org/apache/solr/servlet/HttpSolrCall.java#L291]).
> init() relies on 'cores' object which only has information of local node
> (which is perfect as per design). It should actually be getting security
> information (security.json) from zookeeper, which has global view of the
> cluster.
>
> Example:
> SolrCloud setup consists of 2 nodes (solr-7.3.1):
> live_nodes: [
> "localhost:8983_solr",
> "localhost:8984_solr",
> ]
> Two collections are created - 'collection-rf-1' with RF=1 and
> 'collection-rf-2' with RF=2.
> Two users are created - 'collection-rf-1-user' and 'collection-rf-2-user'.
> Security configuration is as below (security.json attached):
> "authorization":{
> "class":"solr.RuleBasedAuthorizationPlugin",
> "permissions":[
> { "name":"read", "collection":"collection-rf-2", "role":"collection-rf-2",
> "index":1}
> ,
> { "name":"read", "collection":"collection-rf-1", "role":"collection-rf-1",
> "index":2}
> ,
> { "name":"read", "role":"*", "index":3}
> ,
> ...
> "user-role":
> { "collection-rf-1-user":[ "collection-rf-1"], "collection-rf-2-user":[
> "collection-rf-2"]}
> ,
> ...
>
> Basically, its setup to that 'collection-rf-1-user' user can only access
> 'collection-rf-1' collection and 'collection-rf-2-user' user can only access
> 'collection-rf-2' collection.
> Also note that 'collection-rf-1' collection replica is only on
> 'localhost:8983_solr' node, whereas ''collection-rf-2' collection replica is
> on both live nodes.
>
> Authorization does not work as expected for 'collection-rf-1' collection:
> $ curl -u collection-rf-2-user:password
> 'http://*localhost:8983*/solr/collection-rf-1/select?q=*:*'
> <html>
> <head>
> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
> <title>Error 403 Unauthorized request, Response code: 403</title>
> </head>
> <body><h2>HTTP ERROR 403</h2>
> <p>Problem accessing /solr/collection-rf-1/select. Reason:
> <pre> Unauthorized request, Response code: 403</pre></p>
> </body>
> </html>
> $ curl -u collection-rf-2-user:password
> 'http://*localhost:8984*/solr/collection-rf-1/select?q=*:*'
> {
> "responseHeader":{
> "zkConnected":true,
> "status":0,
> "QTime":0,
> "params":{
> "q":"*:*"}},
> "response":{"numFound":0,"start":0,"docs":[]
> }}
>
> Whereas authorization works perfectly for 'collection-rf-2' collection (as
> both nodes have replica):
> $ curl -u collection-rf-1-user:password
> 'http://*localhost:8984*/solr/collection-rf-2/select?q=*:*'
> <html>
> <head>
> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
> <title>Error 403 Unauthorized request, Response code: 403</title>
> </head>
> <body><h2>HTTP ERROR 403</h2>
