Cannot create database connection for Doctrine2 in Symfony2 using MAMP (connection rejected)

I study Symfony2 for a project that some friends and I take over, and I take a tutorial where you make a blog in Symfony2: http://tutorial.symblog.co.uk/docs/doctrine-2-the-blog-model .html

Problem

I can not get Doctrine2 to work. I give the following command to the terminal:

php app/console doctrine:database:create

And get the following error message:

Failed to create database for connection named symfonySQLSTATE [HY000] [2002] Connection rejected
