[Samba] Backup Profiles

[benjamin.dupuis at armorarena-fr.com]

Hello,

I have a small problem,

When login on my Windows XP with the Domain Admin account, I cannot 
backup to my DLT (no access)
When login on my Windows XP with local Admin account, I can acces to all 
share using NET USE /USER except to //samba3/profiles/xxxx who stay Deny.

How to do?
I try to modify the smb.conf [profiles] but I think I didn't do it fine :)
Perhaps there is something to do on the windows XP for Domain Admins can 
access to DLT ?

[profiles]
        path = /home/data1/profiles
        read only = no
        create mask = 0600
        directory mask = 0700
        browseable = No
        guest ok = Yes
        profile acls = yes
        csc policy = disable
        # next line is a great way to secure the profiles
        force user = %U
        # next line allows administrator to access all profiles
        valid users = %U @"Domain Admins",%U @"Backup Operators"
        hide files= /desktop.ini/ntuser.ini/NTUSER.*/


Thanks
