Why might boto be denied access to S3 with proper IAM keys?

Question

I am trying to access a bucket on S3 with boto. I have been given read access to the bucket and my keys are working when I explore it in S3 Browser. The following code is returning 403 Forbidden Access Denied.

conn = S3Connection('Access_Key_ID', 'Secret_Access_Key')
conn.get_all_buckets()

This also occurs when using the access key and secret access key via the boto config file. Is there something else I need to be doing because the keys are from IAM perhaps? Could this indicate an error in the setup? I don't know much about IAM, I was just given the keys.

My guess is that it's because you're calling conn.get_all_buckets() instead of conn.get_bucket(bucket_name) for the individual bucket you have access to.
