Ansible tasks cannot have sudo_user on a certain Vagrant box (bento)

Question

The following task fails on a Vagrant box (ubuntu 12.04 chefless) http://opscode.github.io/bento/

  - name: ensure database is created
    postgresql_db: name={{dbname}}
    sudo_user: postgres

fd

failed: [192.168.78.8] => {"failed": true, "parsed": false}
invalid output was: Sorry, user vagrant is not allowed to execute '/bin/sh -c echo SUDO-SUCCESS-lalargtagydzinzenmftocwaiucrmxuk; /usr/bin/python /tmp/ansible-1392568385.89-150322815243790/postgresql_db' as postgres on cogol-dev.

Will I need to create my own box ?

Probably being late here, but I encountered same error today and resolved it with

username ALL=(ALL) NOPASSWD: ALL

your sudo group missing this ALL in parentheses
