db.runCommand addshard is erroring out.

[ejholm]

I am attempting to add a shard to our DB. I am running the mongos
process on a Windows Server 2008 box successfully. I am running my
mongod and my configsvr processes on a Linux CentOS 6.0 configuration.
It also is up and running. Now I am trying to add the shard to the DB.
While connected to the mongos process on the windows box I run the
command below and get the following error:

mongos> db.runCommand({addshard:"replicaSetName/mongod serverName:
27018"})

{
"ok" : 0,
"errmsg" : "failed listing replicaSetName/mongod serverName:
27018's databases:{errmsg: \"need to login\", ok: 0.0}"
}

Thing is I have not set up any users yet in the database. I did set
auth = true in my config file for the mongod process. But I cannot
find any documentation as to the syntax for the mongos processes.

What do I need to login to? is it a param in the db.runCommand/
addshard? How do I resolve this issue?

Thanks,

Erik

Bumping in hopes of getting a response...

What version is this?

Here should be the docs you are looking for:
http://www.mongodb.org/display/DOCS/Security+and+Authentication#SecurityandAuthentication-ReplicaSetandShardingAuthentication

Scott,

Thank you for your reply. We are using 2.0.2. I will look over the doc
you suggested.

Thanks again.

Erik

Thank you Scott, I believe that was the issue.

Though now I have one other question. I have set up the keyFile on
both the app server(Windows Server 2008) and on the DB server (Linux
CentOS 6.0). The documentation states that the file can only be read
by the current user. So is that saying that the user that started each
process on the different servers must be the same? The owner of the
directory/files on the Linux box is one user, the executor of the
mongos process on the Windows box is another user. Is this a problem?
I'm assuming that it is, due to the log file on the app server, which
I have posted below:

Please let me know what you think.

The user doesn't have to be the same.
--keyfile is for all mongos/mongod, not app servers.
