samba - Feb 2006 - Net rpc share migrate

I'm trying to migrate my NT4 PDC to samba. So I currently have a samba
3.0.14a serveur with ldap backend as running BDC. I successfully migrated
SAM database with net
vampire command. However when I tried to migrate shares (or files... same
error) with this command :
 net rpc share migrate shares test -S 'SERVEURNT4' --acls -v -U
Administrateur%secret

I get this error :
