I'm a longtime admin, but I've always been careful with my groups, so I've never run into this before.
I recently inherited a second instance of Jira from another division of my company. The previous "admin" had not enabled any kind of security; he was essentially a billing contact. Almost every user in the instance had full admin access (which I shut down immediately!) and they were liberal, to say the least, about creating groups.
I'm now trying to figure out what these groups do... Only 5 out of the 100+ groups are providing product access. Is there any way to audit where the other groups are used?
For example, some kind of report that would show me that group A is in the People section of projects 1, 2, and 3, and group B is used in workflow conditions or validators in projects 4, 5, 6.
We are on Premium, if it makes a difference. I'm also willing to install an add-on if there's one that will help.
