I've written a script using the CoreService to traverse every folder and structure group across the whole BluePrint.
This includes the expected settings in the system to get the same authorization setup (or perhaps Security Access Profile, if you will).
However, it doesn't gather the information from a user and Group perspective.
For that, you could either use the outputted .csv file to check manually or adapt the approach to show the same data from a Group, rather than a hierarchical, perspective.
Note that it's been a while since I wrote this and there may be a few shortcuts (hacks) that could have been written in a much cleaner way.
