Mongodb start error with security.authorization enabled

Question

I am getting an error attempting to start mongo with authorization enabled via the security.authorization configuration parameter (see http://docs.mongodb.org/manual/reference/configuration-options/#security.authorization)

On running mongod I get

Error parsing INI config file: unknown option security.authorization
try 'mongod --help' for more information

Any idea? Thanks

Supporting data:

• Mongo version 2.6.0 (installed via homebrew)
• OSX Mavericks 10.9.2

start command:

mongod -f /usr/local/etc/mongod.conf

mongod.conf file (works fine if I comment out security.authorization):

# Store data in /usr/local/var/mongodb instead of the default /data/db
dbpath = /usr/local/var/mongodb

# Append logs to /usr/local/var/log/mongodb/mongo.log
logpath = /usr/local/var/log/mongodb/mongo.log
logappend = true

# Only accept local connections
bind_ip = 127.0.0.1

# auth
security.authorization = enabled
#security.authenticationMechanisms = MONGODB-CR  #error occurs with or without this

No entry is made in the mongo.log file when this occurs

Note: I would have written this as a comment, however I do not have the points yet.

Just wondering whether what you are trying to achieve is authentication instead? If this is the case, all you need to set in mongodb.conf is:

# auth
auth = true   # true or false. Whether or not authentication is required. 

-- UPDATED:

Some other steps that are important:

Configure the db location: Set in mongodb.conf as (you already have this, but should check the directory and permissions exist):

# Store data in /usr/local/var/mongodb instead of the default /data/db
dbpath = /usr/local/var/mongodb

# Append logs to /usr/local/var/log/mongodb/mongo.log
logpath = /usr/local/var/log/mongodb/mongo.log
logappend = true

Dont forget to make sure the above /usr/local/var/mongodb directory and /usr/local/var/log/mongodb/ directory exist. The installer that you used may not have made them.

Create an Operating System user for mongodb: (If one has not already been created - this is how on linux, not sure for osx) - as root:

adduser --system --no-create-home --disabled-login --disabled-password --group mongodb

Add permissions to folders if they are not already set:

chown mongodb:mongodb -R /usr/local/var/mongodb

To setup database user authorization / privileges:
