[Samba] managing Win2K3 ACL from debian server

[Vincent Malien]

Dear Stephen,

thanks for your help, with the the command line:
 mount -t cifs //mywin2k3server/share /mnt/smb/mountingfolder -o
acl,username=vm
I can access to win2k3-hosted shares.
The first problem is solved, but the second is still there; 
it seems that cifs isn't more compatible with Win2K3 ACLs than smbfs.
When I execute:
 setfacl -m u:domainuser:w /mnt/smb/mountingfolder/afile
The answer is still: "Not supported operation ".
Do you know if there is an other way to do this?

Regards.
