What do you mean for disjunction between local administration and users ?
Do you mean :
1. Separation between directory insertion (etheir user or machine) and
local PC admin rights :
- class D people can insert machines, as well as users
- class T people can login to machines as local admin
2. Separation between directory insertion (users inserted by some
people, machine by others) and local PC admin rights :
- class M people (local support I guess) can insert local machine, in
the right ou=site,ou=Computers sub-ou
- class D people can insert users (centrally managed I guess), and maybe
- class T people (see below).
I guess (read I think, but not yet investigated further) that it could
be done, maybe with the help of LDAP management application and
carefully crafted LDAP ACLs.
I think that, if using IdealX scripts, and different sub-ou
configuration for these, you may can do what you intend to, directly
using Samba and inserting machine directly from the Windows PC.

What is the size of the biggest site (I beg it is the Lyon one in
Part-Dieu) ? Or maybe Paris'ones.
I guess that machine passwords traffic (once per week) would not be that
huge, even on 64kb/s lines
>>>I want to minimize network traffic but still keep a central user account
Setup a central directory, replicated to each the 6/10 central sites, or
maybe to each of your 1000 local site. This way, authentication would be
local/not too far away, and machine account password will be ref'd to
the central directory.

Not yet, but on a much smaller site (600 people).
