ad_enabled_domains will ignore requests looking up users and groups from
domains not listed but I guess if a user from domain ad1.example.com is
a member of a group from ad2.example.com this group will still be looked
up.

Setting 'subdomain_provider = none' should disable all kind of domain
discovery. But depending on the other stetting you might e.g. have to
set ldap_idmap_default_domain_sid to tell SSSD about the domain SID of
the local domain to make automatic id-mapping work.
