      When a new collection is added and its data is migrated to another shard (from the primary shard), any mongos which had already authenticated a user to that DB before the collection is sharded and data move happened now cannot see this collection's data on the other shard.

      I think this may be related to mongod setting shard version for that collection to 0 when last chunk is migrated off of it, but that's problematic possibly in similar way we require flushRouterConfig when movePrimary is done for a database.
