Error in facebook example in documentation

[nilsga]

The signature for findOrCreateUser in the facebook connect example is wrong:

.findOrCreateUser( function (session, accessToken, fbUserMetadata) {
    // find or create user logic goes here
  })

The step in the oauth2 module states:

.step('findOrCreateUser')
      //.optional()
      .accepts('session accessToken extra oauthUser')
      .promises('user')

So findOrCreateUser takes four parameters, the third being an "extra" parameter. The OAuth user is the fourth argument. So the example should read:

.findOrCreateUser( function (session, accessToken, extra, fbUserMetadata) {
    // find or create user logic goes here
  })

Otherwise, fbUserMetadata will be 'null' for facebook connect.
