If the data for all users and groups is stored in AD this would be the
most recommended provider. You do not need the Administrator password
for SSSD to operate but a "normal" account which can read user and group
data is sufficient. Typically this is machine account which is created
when you join the Linux host to the AD domain.

If you use realmd for joining the domain realmd will create a basic SSSD
configuration automatically.

To join a domain you do not need the Administrator account either.
Please check the AD documentation how to assign privileges to a "normal"
account so that it can be use to join machines,

You can use 'auth_provider = krb5' with 'id_provider = ldap'

It depends what your central ID provider is and if there already is an
nss module for this provider. If your central ID provider is AD please
see my comments there.
