Testing S3 ABAC Locally

I'm the author of this tool that evaluates effective AWS access locally. AWS launched ABAC support for S3 buckets (https://aws.amazon.com/blogs/aws/introducing-attribute-based...). In this new model you have to turn on ABAC per bucket.

This post shows you can use iam-lens to preview the effects of turning on S3 ABAC locally before actually enabling it on a bucket.
