If you don't have a copy of FileMaker Advanced, beg, buy or steal the $$ to get a copy. There are several major ways that the developer tools built in to advanced can greatly reduce the "headaches" of working with this system.
If you have Advanced, you can generate a database design report and this will list out all privilege sets and their settings.
Thank you! I do have FileMaker Advaced and the database design report is helpful. Now I just need to figure out a way to parse through all the xml, but that shouldn't be too bad.
For what you describe, parsing through the xml shouldn't be necessary. You can use the HTML option and just examine the report in your web browser.
But I will note that there are a number of third party produced design tools that can take the XML from a database design report and so some pretty amazing things with them.
