Has anyone seen a tool that compares permissions between usergroups? What I have been doing is tracking this in a spreadsheet but that gets out of sync occasionally and is manual. A tool that would list each user group and the permission differences between them would be very helpful in managing permissions and troubleshooting when odd things happen.
I'm interested .... but it would be a once-off (or rarely) used functionality, so would need to be very low cost. Something you'd make and sell, rather than expect someone to pay for development up front.
