Having a user with a power role that includes schedule_search capability. And When I'm trying to schedule a dashboard to be send as pdf using schedule pdf delivery feature i got this error [ Sending the test email failed: command="sendemail", 'rootCAPath' while sending mail to: < my email > ]. I didnt face this issue using splunk 6.5.1 before upgrading to splunk 6.6.3. I tried to test the feature using an admin role and it's working fine. But, For power role it's not working. I found in the documentation that the user should have the roles [ schedule_search ] and [ admin_all_objeccts : only if the mail host requires login credentials ] and i dont have this requirement for login. Even i tested it and also didnt work with the admin_all_objects role. Another thing to consider that am using a search head cluster.
