Mahesh Kumar Vasanthu Somashekar commented on SOLR-12514:
---------------------------------------------------------
Hi [~varunthacker]
Yes, I'm using Solr-7.3.1
Create another user without 'search-user' role, meaning user doesn't have
access to 'test_collection'.
Run query using this user hitting all Solr nodes.
You would see 200 response from nodes which doesn't have replica (which is not
expected) and 403 response from nodes which has replica (expected).
Thanks.

> 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=*:*'
