MongoDB: dbclient_rs replSetGetStatus failed{ ok: 0.0, errmsg: “unauthorized” }

When I'm using mongodump or mongorestore on a replica set these messages appear in the verbose output:

dbclient_rs replSetGetStatus failed{ ok: 0.0, errmsg: "unauthorized" }

The replica set is configured for authentication and the user account I'm connecting with has the clusterAdmin role set, which makes me wonder why the clients (mongodump/restore) aren't authorized to execute replSetGetStatus.

The connecting user has the userAdminAnyDatabase, readWriteAnyDatabase, dbAdminAnyDatabase and clusterAdmin roles on the admin database.

Here is an exemplified mongodump command:

mongodump --host rs0/host0.example.org,host1.example.org,host2.example.org \
          --port 27017 \
          --ssl \
          --ipv6 \
          --verbose \
          --authenticationDatabase admin \
          --username *user* \
          --password *password* \
          --out bakdir \
          --db admin

mongod, mongodump and mongorestore are version 2.4.10, installed from the Debian Jessie (stable) repository.

I'd like to know why it fails, what the implications of these failings are and what I possibly can do about it (except switching off authentication ;-). Besides this quirk mongodump/restore seem to do their jobs just fine.

Here is the verbose log output from mongodump (timestamps truncated and hostnames replaced):
