Does your application prompt users for their username and password or does
it have one listed in the configs somewhere to access fas?  I'm not
familiar with the .fedora_session format, does it store everyone's
sessions?

I'm asuming that if someone had access to it they'd be able to become
whoever was logged in at that time.  Probably to other applications as
well.  I'd like to hear Toshio's advice on this, I believe he's the
primary architect of how .fedora_session should behave
