samba - May 2007 - uid mapping

Hi

It's me again ;-)

I have set "idmap uid = 10000-49999". But my ads users have now
uid's
starting from 5000.
And the new Files from this users have MYDOMAIN:MYDOMAIN as owner. I
think this should be MYDOMAINUSERNAME:MYDOMAINGROUP.

Any ideas? I think it's almost done...
