I have  BIND 9.10.4-P2 installed; I believe that it is setup correctly, and
it is not running.

smb.conf:
# Global parameters
[global]
        netbios name = DC2
        realm = MBOK.CO.UK
        workgroup = MBOK
        server role = active directory domain controller
#       server services = -dns ## This is to uncomment once switched to
bind.##
        idmap_ldb:use rfc2307 = yes
        dns forwarder = 192.168.50.5
        nsupdate command = /usr/local/bin/samba-nsupdate -g

        vfs objects = zfsacl
        store dos attributes = Yes
        ea support = yes
        map acl inherit = Yes

        ## Usee nfsv4 acls
        ##  => See README.nfs4acls.txt for more information
        ## Use OWNER@ and GROUP@ special IDs
        nfs4:mode = special
        ## Merge duplicate ACEs
        nfs4:acedup = merge
        ## Enable changing owner and group
        nfs4:chown = yes

[netlogon]
        path = /var/db/samba4/sysvol/mbok.co.uk/scripts
        read only = No

[sysvol]
        path = /var/db/samba4/sysvol
        read only = No

named.conf to follow.

Many thanks for your help.
