Ruby Amazon S3 Access Denied when listing buckets

Ruby newb here.

I was given access creds to data on the amazon cloud. Im beginning to think the access keys are off but I could be wrong. Someone help!

I have the aws folder as a plugin

>> Version
=> "0.6.3"

>> AWS::S3::Base.establish_connection!(:access_key_id =>'*******', :secret_access_key => '*****')
=> #<AWS::S3::Connection:0x007fd0539bb4c0 @options={:server=>"s3.amazonaws.com", :port=>80, :access_key_id=>"****", :secret_access_key=>"****"}, @access_key_id="****", @secret_access_key="****", @http=#<Net::HTTP s3.amazonaws.com:80 open=false>>

>> AWS::S3::Service.buckets   
=> AWS::S3::AccessDenied: Access Denied

You can fix this in following way.

1. First go to s3 console in amazon.
2. Then click on bucket.
3. Then click on properties tab in right side.
4. Then click on permission options
5. Click on add more permission
6. Check the all checkbox and save it.
