For many management tasks the normal Windows RPC API already
provides good interfaces. Creating a new user is covered by
the SAMR interface for example, setting security descriptors
is another example. A very terse but quite complete
reference of what Windows already provides can be found in
the Samba4 source/librpc/idl subdirectory. User management
is in samr.idl, share management in srvsvc.idl and so on.

What we are talking about here is what the Windows RPC
interfaces can not provide because it does not have any
counterpart in the Windows world. There's tons of smb.conf
options that just don't make sense under Windows, 'store dos
attributes' would be one example here. This is where we have
to go beyond the native Windows functions. Creating a share
for example could be done via the srvsvc pipe, setting a
special per-share configuration option could then be done in
a special registry key that has magically popped up. Or for
example setting the unix-style login shell of a user could
also be done via some registry hack. So we would like to
build upon a quite rich API and provide backdoors via the
winreg pipe.

You are doing base infrastructure work for this by plugging
libelektra into this picture.
