I am Using Visio 2013 Web Site Map to create a visual representation of the SP2007 Site and folders. I need to incorporate showing permission groups (showing broken inheritances too). There does not seem to an automated way to do this. I hate to resort to manually typing in the permission groups. Any ideas?
For SharePoint 2007, there is the SharePoint Administration Toolkit which has a Permissions Reporting Tool.
If you need the Visio aspect, you could possibly try taking the output of this into a data connection in Visio.
