this will mean that all profiles and authentication goes over the vpn
probably not a good idea (as you say below)

again - all authentication goes over the wan

PDC (or another machine) at each site.  That way everybody can log in
even if the lan is down (though the distributed ldap dbs might diverge
if your wan is down for a long time.
