Yes, you can probably forget most if not all of the LDAP parameters, 
samba4 in AD Mode just doesn't work like samba3.6 + openldap.
You probably have something like this in smb.conf:

# Global parameters
         workgroup = EXAMPLE
         realm = example.com
         netbios name = DC1
         server role = active directory domain controller
         server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, 
drepl, winbind, ntp_signd, kcc, dnsupdate
         idmap_ldb:use rfc2307 = yes

         path = /var/lib/samba/sysvol/example.com/scripts
         read only = No

         path = /var/lib/samba/sysvol
         read only = No

As you can see, there are no ldap lines!

What you have to understand is that you need to connect to samba4 AD 
just like you would connect to windows AD and will need to use different 
commands i.e samba-tool and/or ldb-tools for instance.

You can extend the schema fairly easily, autofs, sudo etc are being used 
fairly extensively.
