We currently have a Tridion CM server where search is working fine in a production environment.
We have cloned this server to create a new machine in a test environment, and changed the MTS user. Everything is working fine, except the solr search. We have changed the MTSuser to a different user in the tridion configuration snap-in, but the error we receive is : "user is not in required role".
There must be some small configuration setting we're missing, but we can't find what the problem is. Anyone has an idea/pointer where to look ?
