samba - Dec 2013 - Troubles getting samba4 working (from samba 3)

Our current environment is Samba 3 with an LDAP backend. I want to move to
Samba 4 with an AD backend. We already have the AD servers in place and
Samba 3 servers are using AD absolutely perfectly. The last remaining piece
is to move Samba 3->4.

My existing Samba 3 configuration looks like this:

[global]
        server string = 1220 Boothost Server
        netbios name = BOOTHOST-1220
        realm = AD.DOMAIN.TLD
        workgroup = DOMAIN
        security = ads
        encrypt passwords = yes
        map to guest = Bad User
        log file = /var/log/samba/%m.log
        log level = 1
        max log size = 0
        domain logons = no
        os level = 75
        preferred master = no
        domain master = no
        dns proxy = no
        delete veto files = yes
        veto files = /*desktop.ini/*$RECYCLE.BIN/
        veto oplock files = /*.xls/
        smb ports = 139
        load printers = no
        server signing = disabled
        printing = bsd
        printcap name = /dev/null

[homes]
        valid users = %S
        comment = Home Directories
        read only = no
        create mask = 0664
        directory mask = 0775
        browseable = no
        csc policy = disable

[shared]
        path = /home/1220/shared
        comment = Center Shared Directory
        create mask = 0770
        directory mode = 0770
        browseable = no
        writeable = yes

[pcsetup]
        path = /var/www/pcsetup
        comment = PC Setup Data
        public = yes
        writeable = no
        browseable = yes

[printsetup]
        path = /opt/samba/printers
        comment = Printer Setup Directory
        public = yes
        writeable = no
        browseable = no

Obviously, things have changed between versions. However, I'm finding it
EXTREMELY difficult to get this configuration moved to Samba 4.

When I try to start it with this configuration, I see this:

root at boothost:/etc/samba# /etc/init.d/samba4 restart
Stopping Samba 4 daemon: samba.

I really need the oplock stuff, but... smb4 doesn't seem to have these
options. I'm not finding anything useful on migrating the configuration
file either.

I don't need to do an in-place migration of the servers. All users and
groups are in LDAP/AD. They shouldn't be any issue in my migration. I just
need to figure out how to achieve in an smb4 config what I'm doing in this
smb3 config.

I'm completely lost... :(

Hi, I think that you are more than lost, your smb.conf points to it 
being an AD member client, but you are trying to start the 'samba' 
daemon, this daemon is only used by the Active directory domain 
controller, so what do want the machine to be, a client or a server?
