Sounds like policykit, then. Someone with policykit experience might be able to tell us how to ask the system which privileges are required to access that file, and then how to ask the system to give those privileges to a given user. (Not knowing much about policykit, but knowing some of what it's capable of, this would be something I'd like to hear.) -- :wq
