Is there a way to pass a user's authentication data to the report? (What username, what group, etc vs a passed along URL and so on).
Specifically, I want to be able to set limits on what people can do with a report based on who they are. That way, I can prevent users who might not understand all the work being done behind the scenes from trying to generate obscenely huge datasets and taking down reporting for everyone -- while still allowing this feature for people who understand its impact and can choose accordingly.
