No problem.

Yes I know what it says there, but 'man idmap_ad' still says the ranges
mustn't overlap (okay, is says 'disjoint', but this the same thing)

Setting 'winbind use default domain = yes' means that all your users
will be treated as being members of the 'MASTER' domain, now this might
seem to work for you, but I think it is going to end in tears ;-)

When it comes down to it, they are your domains and you can do as you
