# The reason for such complicated method is a user which can read the oplog on a replicaset
|
|
|
|
|
# This user must have access to the local DB, but since this DB does not have users
|
|
|
|
|
# We must be aware of users which can read the oplog on a replicaset
|
|
|
|
|
# Such users must have access to the local DB, but since this DB does not store users credentials
|
|
|
|
|
# and is not synchronized among replica sets, the user must be stored on the admin db
|
|
|

# {
|
