[Samba] VSS on samba

We have recently moved our VSS database from windows 2k to samba,
initially all looked fine but have come accross a problem.
Quite often VSS complains saying it can't write to "names - acess denied".
The file its refering to is names.dat in data/ (for those that know VSS)
I believe this to be some sort of locking issue. Sometimes getting all
other clients to quite VSS solves the problem, sometimes it doesn't.
smbstatus reports things like:
5031 DENY_NONE 0x2019f RDWR NONE
/home/wdb-uk/store/vss/database/data/names.dat
which afaik, shouldn't be stoping anyone from writing to it.
Although sometimes no locks appear for it at all and still VSS reports
you can't write to it.
Viewing the file via the share I can edit it by hand (well write to it
anyway - its some dodgy proprietry format)
The smb conf for the share is as follows:
[vss]
comment = Visual Source Safe
read only = no
browsable = yes
path = /home/wdb-uk/store/vss
create mask = 0660
directory mask = 0770
oplocks = False
level2 oplocks = False
with no other locking options specified anywhere else.
I've tried with and without the oplocks statments and there is no
difference.
There is apparerntly some way of getting VSS to use file locks where by
it creates a lock file in data/locks/ for each locked file, but I can't
seem to find any docs saying how to do it.
The only other notible point is that /home/wdb-uk is a mounted nfs share
but I have tried having it locally with the same issue.
Anyone come across similar problems with VSS, google seems to report
various locking issues but no real solutions.
Thanks
Nathan
