Ansible and AWS user for boto

Hi,

Does the AWS user in the .boto file have to be in the Administrators group? I’m only using ansible to manage EC2 instances, but if I try using a user with just ec2:* access (or the configured AmazonEC2FullAccess policy)I get auth error:

ERROR: Inventory script (/etc/ansible/hosts) had an execution error: Error connecting to AWS backend.
You are not authorized to perform this operation.

I don’t particularly want the .boto user to be a full admin user.
