[Samba] Issue with reshare shares

Hi there,
we have a customer with some old Windows 98 stuff. The
network has been migrated to a 2008 domain and Windows 98 won't
authenticate (and thus can not access shares, also all computer names
(DC's / fileservers) are longer than 8 characters).
Figured I would
mount the shares on the fileservers on a linux box (ubuntu 10.04 LTS 64
bit server) and then export them again through Samba.
At first glance
this seemed to operate fine, unfortunately it does not. Several piece of
ancient software (that'll cost several millions to replace :() use an
access database (.mdb file). When accessed through the linux share and
anything else writes to it at the same time (be it going directly to the
share or through the linux box resharing them (not all boxes accessing
it run 98, there's also NT4, 2000 and XP boxes which all can connect to
the shares directly w/o issues)) the database will get corrupted.
I'm
guessing file locking or something similar doesn't work properly this
way, causing writes to go simultaneously in a non-safe way, causing the
corruption.
Any ideas if this can be solved?
Currently I mount from
/etc/fstab with:
//10.1.1.5/Programma /mnt/programma cifs
username=reshare,password=,noperm,directio,dir_mode=0777,file_mode=0777
0 0
//10.1.1.5/JMS /mnt/jms cifs
username=reshare,password=,noperm,directio,dir_mode=0777,file_mode=0777
0 0
I added directio in hopes of solving it, but unfortunately it
doesn't seem to make a difference.
Further below is the testparm -v
output (for complete config w/o additional comments).
Any
hints/suggestions are very welcome :).
Kind regards
