[Samba] OS 10.3.3 client File saving problems

[Karl Meisterheim]

Hello,

I administrate a modest network of 12 Mac (os x 10.3.3) and PC clients
(win xp) connecting to a Samba server running Redhat enterprise Linux 3
and Samba 3.0.2

We just recently switched to this configuration from a Win2000 file
server running SMB and AFP that did not have any of the issues I list
below.

My OS X users are running into occasional yet persistent problems saving
files to the samba shares.  Here's a list:

1) File date modified times are not updated when a file is changed and
saved, unless the file is saved using "Save As" (Photoshop CS)

2) Sometimes after working on a file (having opened it from the server),
you cannot save it back to the share. (Quark 6, Indesign CS, Photoshop
CS)

3) Sometimes a user cannot open or save a file.  The solution in this
case is to remove the resource forks (._*) files.  Vetoing these files
by default causes permission problems with the OS X machines.

I'm using ext3's acl support to handle permissions and that seems to
work fine.

Here's my smb.conf file.  As you can see, I've tried a lot of different
things after reading this lists archives and googling for a few weeks.

dos filetimes = yes
#dos filetime resolution = yes
dos filemode = yes
# Should help with weird mac characters
unix charset = UTF8
dos charset = ASCII
unicode = yes
# prevent resource forks
#veto files = /._*/
#delete veto files = yes
log level = 4 
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

[Production]
        path = /home/shares/Production
        writeable = yes
        invalid users = %S
        oplocks = false
        level2 oplocks = false
        dos filetimes = yes


Any insight would be welcome,

Thanks.
