Subject Basic auth and index replication
Date Wed, 03 Apr 2019 08:15:17 GMT
Hey Solr community.

I’ve been following a couple of open JIRA tickets relating to use of the basic auth plugin
in a Solr cluster ( ,
and recently I’ve noticed similar behaviour when adding tlog replicas to an existing Solr
collection.  The problem appears to occur when Solr attempts to replicate the leaders index
to a follower on another Solr node and it fails authentication in the process.

My environment

Solr cloud 7.6

Basic auth plugin enabled


Has anyone else noticed similar behaviour when using tlog replicas?
