I wanted the script to do a few things. Tell me who is in a AD Group that was granted rights. IT is one thing to see the group name, but that doesn’t really tell me who has access. I also wanted the output to be a little more user readable, so I formatted the output some. There are other things I did too, but you can fun reading through the code and comparing the 2 sources.
Knowing who’s allowed to do what is key to having a successful security posture. This script won’t tell you object-level permissions, but at least gives you an idea about role and group membership.
