Hi everyone and thanks in advance for your time.
I'm experiencing the same problem on a mixed network (Zentyal Community Edition 3.3.2 with WinXP sp3 clients fully updated, Office 2003/2010).
I'm experiencing the same issue with Word and Excel 2003, but MSOffice2010 users are also complaining. Spent the entire night googling but it seems there's no easy way out, the solutions seems to be stopping the antivirus service (which i also tried without results) or changing the way samba handles locks via /usr/share/zentyal/stubs/samba/smb.conf.mas (still nothing changed).
When checking the directory permissions with ls -l the output is:
drwxrwx---+ 2 ebox __USERS__ 4,0K gen 27 04:20 test
which seems correct.
ls -l on the folder content shows:
-rwxrwx---+ 1 ebox __USERS__ 18K gen 27 02:48 Copia di Nuovo Foglio di lavoro di Microsoft Office Excel 97-2003.xls
-rwxrwx---+ 1 x.moro __USERS__ 17K gen 27 04:11 Nuovo Foglio di lavoro di Microsoft Office Excel 97-2003.xls
x.moro is the user which first copied the file into this folder, but since the issue shows with both files seems to be unrelated who the owner is.
I'm attaching my samba.log (which shows my frustrating night activity) and (unmodified) smb.conf.
I'm stuck with this, any help would be precious!
