[Samba] MDB Files

[Kaz _]

Hi.
I have a problem with Ms Access *.MDB files.
When I tried to edit forms it takes at least 60 seconds  to edit that forms
also to edit query. Application is working fine. But editing ... horrible.
I added these lines in my smb.conf file but nothing
     oplocks = no
    level2 oplocks = no
    strict locking = no
    fake oplocks = no
    veto oplock files =
/*.MDB/*.mdb/*.LDB/*.ldb/*.DOC/*.doc/*.XLS/*.xls/*.DOCX/*.docx/*.XLSX/*.xlsx


many tables are linked to another databases located on the network. There is
no problem to edit file locally.
samba version :3x 3.5.4.
os rhel5.7
Thank you.
