[Samba] samba 3.2

[dis]

I've just made an upgrade from samba 3.0 to samba 3.2. Everything works fine except one detail. We are using a Paradox database located on one of the Samba shares (prod). After upgrade to 3.2 we can no more create Paradox script files (.ssl) on this share. On save, Paradox says "Unable to write in this file". On 3.0 it worked fine.
Here is my configuration:
Version 3.2.1-0.1.126-1867-SUSE-SLES10

        map to guest = Bad User
        printcap name = cups

        logon path = \\%L\profiles\.msprofile
        logon drive = P:
        logon home = \\%L\%U\.9xprofile
        domain master = No
        ldap ssl = no
        idmap uid = 10000-20000
        idmap gid = 10000-20000
        cups options = raw

        include = /etc/samba/dhcp.conf

        path = /home/prod

        create mask = 0777
        force create mode = 0777

        force directory mode = 0777
        inherit acls = Yes
