[Samba] Archive attribute problem

[Carlo Piga]

Hello,
I 've just spent some trouble in tryng to  fix archive attribute.
At thi time a samba user different from the owner of a file can't set or 
unset the archive attribute from a Windows Client.
Anyone know how to fix it?
Please help me, It's a long time that the backup  is unavailable and a 
hardware failure of the HD is coming....I'm sure...
Bye,
Carlo Piga
