I agree. But that's not what FMDS is doing. They are basically trying to re-invent
the wheel by adding all kinds of arguably redundant mechanisms to the spec. I think
this is what happens when you let a bunch of storage engineers design a network. Just
read TP-8010 and TP-8009 to see what I mean.

I proposed TP-8014 because I saw the mess coming and I wanted some simple way to make
things work... at least with authentication.
