i was wondering what happens if you have a Parent domain Contoso.com
and then a child domain child.contoso.com,
and have a Azure AD Domain Services aadds.child.contoso.com with Contoso as a Managed domains not federated.
how does Azure AD handle those domains if you have to federate the parent one day?
since Federation on the Parent will filter down to all the subdomains, and i suppose it will effect the AADDS domain as well.
