Start pbm-agent on shard node error

I have a MongoDB cluster with three config nodes and three shard nodes and work on pbm backup setup. I can start pbm-agent on config nodes but failed to start pbm-agent on shrad nodes with error. Do I need to have separate user account for config node and shard node?

Hello, the backup user needs to be created locally on each shard node and the config servers. Creating it through mongos router won’t be enough. Hope that helps!
