samba - Apr 2013 - SAMBA 4.0.5 - AD/DC part of an existing AD

Hi,
My problem relates to SAMBA 4.0.5, especially with acl / ntacl problem.

Explanation:
     I'm currently trying to install a TEST System with a Samba4 ADDC 
system, using Ubuntu server 12.04.
     I've successfully completed the install and followed mostly the 
howto's on samba.org for SAMBA4.

     I'm currently struggling with changing ACL on the Samba 4 Share 
itself, and inside the shares...
     It's now been a few weeks that I've started working on this, 
starting with 4.0.3 to 4.0.4 and now 4.0.5.

     Using the windows Admin Pak, I simply can't change the ACL to 
"Domain Admin" on the share itself;
     It's always giving me a "Permission Denied".

     I can't seem to find the error in the samba logs, logging at 
different levels.

Here's the setup I've used:

     krb5.conf:
================================[libdefaults]
         default_realm = mydomain.com
[realms]
         mydomain.com = {
                 kdc = maindc.mydomain.com
                 admin_server = maindc.mydomain.com
                 default_domain = mydomain.com
[domain_realm]
         .mydomain.com = mydomain.com
================================
     smb.conf:
================================[global]
         workgroup = MYDOMAIN
         realm = mydomain.com
         netbios name = FSLINUX2
         server role = active directory domain controller

[netlogon]
         path = /usr/local/samba/var/locks/sysvol/mydomain.com/scripts
         read only = No

[sysvol]
         path = /usr/local/samba/var/locks/sysvol
         read only = No

[TEST]
         comment = Repertoire de base pour donnees
         path= /TEST
         read only = no

Well, this is ambiguous; I was not able to associate the ACL situation 
with a specific error message...
This is the only message that may be related, there no WERR_ errors, no 
other NT_STATUS errors at the time I've tried to add/change ACLs...

Please let me know if I can provide any further information to help me

Thank you all for your help and listening.
