Hello I'm on the Solr 8.1 branch off commit f26388d034fe5eadca7416aa63b509b8db2c7688 so I have the authentication fixes from SOLR-13510 (intermittent 401s for internode requests)
When trying to use the new REINDEXCOLLECTION command with basic auth enabled, the daemon stream fails with repeated 401s when trying to access the target collection. This might be the same problem as SOLR-13472, except it applies even with a single node, and this doesn't require role based configuration. Repro: I added a reindex request in BasicAuthIntegrationTest and it is reproducible in there... I don't know what effect it should have on the auth metrics, if it were working correctly, so I don't know how to update the test properly. But you can add the request towards the end of org.apache.solr.security.BasicAuthIntegrationTest.testBasicAuth() * CollectionAdminRequest.ReindexCollection reindexReq = CollectionAdminRequest.reindexCollection(COLLECTION); reindexReq.setBasicAuthCredentials("harry", "HarryIsUberCool"); cluster.getSolrClient().request(reindexReq, COLLECTION);* Manual Repro: run bin/solr -e cloud Choose 1 node / 1 shard / 1 replica In browser GET http://localhost:8983/solr/admin/collections?action=REINDEXCOLLECTION&name=gettingstarted will succeed Enable security: server\scripts\cloud-scripts\zkcli -zkhost localhost:9983 -cmd putfile /security.json <path to file with this> { "authentication": { "blockUnknown": true, "class": "solr.BasicAuthPlugin", "credentials": { "solradmin": "fskh17INKrOTSRCJ8HkamA0L6Uiq1dSMgn4OVy8htME= /Q4VgOkwVlP6AMVY+ML+IuodbfV81WEfZ3lFb390bws=" } } } In browser authenticate (as solradmin : solradmin) and GET http://localhost:8983/solr/admin/collections?action=REINDEXCOLLECTION&name=gettingstarted will time out after 180 seconds The solr log will show repeated 401s Setting "forwardCredentials" : true in the security.json does not appear to change the outcome. responses.txt <https://drive.google.com/file/d/1h_vQCrf5KyZAK6TIG6fPzMNxBL1Rx1bT/view?usp=drive_web> solr.log <https://drive.google.com/file/d/10oYL3AtECxmei7cVOKAM5JPKEt8lFh67/view?usp=drive_web> security.json <https://drive.google.com/file/d/1xVbXcDEq2btbTycBdXLe3Evz5zIYxm9o/view?usp=drive_web>
