I tried to catch this scenario:
id_provider=ldap
autofs_provider=ldap
ldap_schema=ad
With the previous versions, the attributes pointed to automountMap etc.
And there is a chance (unlikely) the admin extended the schema to keep
the config using defaults.

Right, that's the reason we should to change the defaults. AD only has
the most basic rfc2307 and our previous defaults forced the AD SSSD
admins to either change the mappings in the config file or extend the
schema.
The patch should fix ticket #2858;
and this ticket says: autofs_provider = ldap ldap_schema = rfc2307
and the 4th comment says: The beauty of using older schema (rfc2307) to store
automount information is, that we do not need to extend AD schema - which
is in many cases quite troublesome action.
So the warning should be logged for rfc2307 and not for AD.
BTW it looks like we needn't change defaults for AD.
