Since the tempest-deployer-input.conf supported, the deployed application (triploe) expected to provide information for tempest runs.
When the cinder backup is configured to use swift as backend, and it passes the client's credentials to swift , the client also has to have permission to swift.
At the moment the following roles gets access permission to swift: admin, swiftoperator, ResellerAdmin
tempest creates user with only _member_ role ([auth]tempest_roles by default.
The operator role is not some high privilege role, all authenticated user could get it without an issue (As long as they pay for the storage ;-) ).
swiftoperator role as any other role by the default policy.json files, would grant enough permission to the user to use services like nova.
please make sure when tempest creates an user with the roles listed in [auth]tempest_roles, that user also able to create cinder backups.
The small hack would be to simple add [auth]tempest_roles = swiftoperator tempest-deployer-input.conf whenever the swiftoperator is created.
Please do not add the 'admin' role [auth]tempest_roles ever.
