      The "copydb" command can be used to copy one database to another within a cluster. For a single node and a replica set, this is just the same node, but for a sharded cluster the target shard actually needs to run queries on the source shard to pull all the data for the database. The problem here is that the target shard fails to authenticate with the source shard.

      To fix this, I believe the "copydb" command needs to know whether it's copying from a node within a cluster or from another cluster, since the way it should authenticate is different in each case.
