Luke - this is the new rpc malloc code I described to you.
Look at how it is used for guidence in re-writing the other
rpc calls.
The nt security descriptor stuff is now re-written to use this,
but doesn't give any advantage over the current SD stuff.
I am in the process of adding the mapping from UNIX perms
to displayed NT ACLs.
Jeremy.
