samba - Dec 2003 - No share access from a windows client to Samba 3.0 / winbind / ADS Server 2003

The context: samba 3.0+windbind+MS ADS Server 2003
I can't see or access to my samba share through my AD 2003 domain

To summarize: 

The Kerberos connection: ok 
The record of  Samba server in the AD : ok 
The record of Samba server in the Server 2003 DNS: ok
The nsdc daemon is shutdown.


The facts:
 
I can see the Samba in the Active Directory manager, but can't manage it
(even the Shares : no permission to see the list of shares).
I can see the computer as a member of the domain but no shares appears!!
 
I checked winbind it seems to be ok as you can see below:
 getent group : ok, getent passwd : ok, wbinfo -u : ok , wbinfo -g : ok,
wbinfo -U 10004: ok 


May be the only clue I found is :  
chown toto file_name
chown: toto invalid user 
 
If I read the doc that looks like the nscd daemon is active but it's not
the case

wbinfo -U 10004 
S-1-5-21-1289177223-2746517356-1178275911-1107
