title: Mongodb start error with security.authorization enabled
body: <p>I am getting an error attempting to start mongo with authorization enabled via the security.authorization configuration parameter (see <a href="http://docs.mongodb.org/manual/reference/configuration-options/#security.authorization" rel="nofollow">http://docs.mongodb.org/manual/reference/configuration-options/#security.authorization</a>)</p>
  
  <p>On running mongod I get</p>
  
  <pre><code>Error parsing INI config file: unknown option security.authorization
  try 'mongod --help' for more information
  </code></pre>
  
  <p>Any idea?
  Thanks</p>
  
  <p>Supporting data:</p>
  
  <ul>
  <li>Mongo version 2.6.0 (installed via homebrew)</li>
  <li>OSX Mavericks 10.9.2</li>
  </ul>
  
  <p>start command:</p>
  
  <pre><code>mongod -f /usr/local/etc/mongod.conf
  </code></pre>
  
  <p>mongod.conf file (works fine if I comment out security.authorization):</p>
  
  <pre><code># 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
  </code></pre>
  
  <p>No entry is made in the mongo.log file when this occurs</p>
