Your 'idmap config' lines are incorrect, you shouldn't be using the
'ad' backend for the default (*) domain. I also wouldn't use the
'1000-999999' range at all, you cannot have any local Unix users, what
happens if Samba fails and you need to login locally ?
You do not have lines for the 'MY' domain.

Have you read this:
