Drifting a bit OT, but one filesystem I knew years ago used ACLs and separated list and use permission. So if you had list permission you could see it existed. If you had read or use permission you could open or cd into it. So it wasn't unusual to have use but not list permission, in other words if you knew it was there you could access it but you couldn't find out whether it was there. And if you didn't have permissions you never got a meaningful error message. EVERYTHING simply returned the error "no information" if it failed. Dunno whether that fits in with SQL or firebird permissions.
