Your setup looks sane and correct. i'm relieved :-)
I'll discuss this with the upstream developers ;-)
imo the problem is with powerpoint and how it treats it's files, and you have to work around this... i found several threads on that topic when searching on google to debug the issue. [ as i remember from some explanation i found: powerpoint opens the file on access and writes something about the access event into the file - then resets the modification time to the value it had found on access - and that is the problem on the samba server side. from what i observed when debugging the issue, this explanation seems reasonable. ] thanks for taking care and looking into that problem ! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
