Hello @jkoral 

Thank you for reaching out to the Cloudera Community

From the error it seems privilege issue. Could you please confirm if you have provided the below permission in the DB

GRANT ALL PRIVILEGES ON <db-name>.* TO 'rman'@'%';
GRANT ALL PRIVILEGES ON <db-name>.* TO 'rman'@'localhost';
GRANT ALL PRIVILEGES ON <db-name>.* TO 'rman'@dmidlkprdls01.svr.luc.edu' 

If not, please do the same and restart the Reports Manager.Ensure that you are providing the correct DB details in CMS >> Configuraiton >> Reports manager >> Database

We will be waiting for your response

Thank you
