[Samba] Linux client have problem with Samba share

[Cybionet]

Greating all,

I want to use Acomba (Fortune 1000) with a database on a samba share. 
All work perfectly with Windows client, but the Linux client can't open 
the database file. Any idea?

Similar thing with Openoffice 2.x. The Windows client can save properly 
file on samba share, but Linux client have a error message when they try 
to save. Linux client need to press save two time to successfully save 
they modifications.

Any idea to help?
