Well, yes but no ;-)

Lets put it this way, user 'DOMAINA\fred' could be 'Fred Flintstone'
and user 'DOMAINB\fred' could be 'Fred Bloggs', they have the same
samaccountname (in different domains), but are actually different
people. If you use 'winbind use default domain = yes' they will become
the same 'fred'. Fred Flintstone is the boss and as such needs to see
everything, Fred Bloggs is employed to sweep the floor, do you really
want Mr Bloggs to see all of the bosses files ?
