samba - Sep 2015 - winbind does not work+sernet package+samba 4.2

Hello

After failing to join my samba box to winAD 2012, I went and downloaded 
the sernet packages
and samba box join the AD domain using "samba-tool" with no problems.
However I've got problems with winbind.

wbinfo -u returns:

could not obtain winbind interface details: WBC_ERR_WINBIND_NOT_AVAILABLE
could not obtain winbind domain name!
Error looking up domain users

Here is my SMB.CONF
----------------------------------------------------------
[global]
   server string = Samba4 file server
   workgroup = TESTAD
   security = ADS
   realm = TESTAD.BIO.AC.UK


    domain master = no

    local master = no
    os level = 0
    browse list = yes


   encrypt passwords = yes
   template shell = /bin/bash
   netbios name = JIMMY
   name resolve order = bcast

   idmap config *:backend = tdb
   idmap config *:range = 2000-3999
   idmap config TESTAD: backend = rid
   idmap config TESTAD: range = 10000-99999


    winbind trusted domains only = no
    winbind use default domain = yes
    winbind enum users = yes
    winbind enum groups = yes
    winbind refresh tickets = Yes
    winbind expand groups = 4
    winbind normalize names = Yes

[realms]
         TESTAD.BIO.AC.UK = {
                                     kdc = TESTSERVER1.TESTAD.BIO.AC.UK
                                     default_domain = TESTAD.BIO.AC.UK
                                   }

[domain_realm]
              .testad.bio.ac.uk = TESTAD.BIO.AC.UK
              testad.bio.ac.uk = TESTAD.BIO.AC.UK
-------------------------------------------------------------------

Any suggestions, please?

Many thanks for you help

Is winbind running ?
What does 'ps ax | grep winbind' show ?

Your /etc/krb5.conf only needs to be this:

[libdefaults]
      default_realm = TESTAD.BIO.AC.UK
      dns_lookup_realm = false
      dns_lookup_kdc = true

Does /etc/resolv.conf point to the DC as the first nameserver ?
