[Samba] oplocks for Access DB

[sond]

Hi Folks

First time poster here..

I have a Samba 3.4.7 ( will upgrade soon ) in a workgroup enviroment,
This server has a share containing various Access DB backends..

Wondering about the .ldb lock files that the client front-ends produce.. 
and if the oplocks and veto options are still current ?
as various combinations i have tried don't seem to work..

Would be keen to hear how others handle Access back ends on Samba shares..

cheers
