[Samba] Excel cannot save modifications. No errors for user

[Carlos Eduardo Valente]

Text:
The problem occurs on any excel file that this especific user try to change.

Environment:
- XLS file saved on the samba server and then opened from the same server.
- User Machine has windows XP and Office 2007. It happens on office 2010 too.
-When the user goes clicking SAVE few times on the excel, no error mesages are shown. But when he close the file and open again, some informations are there and others no.
-When we copy the file to the user machine, edits and then send back to the server it works.
