[Samba] modification time inconsistency

[Carlos Knowlton]

Hello,

I have a client with a windows utility that relies on "touch"ing (changing
the mod time) on zero-length files in a folder for the purpose of judging
when that folder was last accessed.  This works fine for him on mapped
windows servers, and from the local disk, but from a Samba (v3.0.22) volume,
the mod time doesn't change unless there was an actual data change within
the file.  (ie, clicking "save" in notepad doesn't change the mod time
unless he enters some data first.).  I know this seems pretty trivial, but
it seems to make all the difference for some backup and SCADA software
packages.

Any ideas what I could do to fix this?

This is what the smb.conf looks like:

[global]
       security = user
       netbios name = Server1
       server string = Server1
       workgroup = WG
       comment = File Server
       os level = 1
       create mode = 771
       force create mode = 771
       directory mode = 771
       force directory mode = 771
       force user = administrator
       force group = users
       map to guest = Bad User
       null passwords = Yes
       passdb backend = tdbsam, smbpasswd
       case sensitive = No
       username map = /etc/samba/smbusers
       template shell = /bin/bash
       dont descend = /proc,/dev,/etc,/usr
       winbind cache time = 10
       log level = 1
       max log size = 2000

[Public]
       writeable = yes
       only user = yes
       write list = @Public
       path = /home/users/Public
       comment = Public Share
       valid users = @Public
       user = @Public

Thank you!
