[Samba] Only one person can use a file at a time problem

[piersk at bda.org.uk]

Hello all,

Migrated a Windows 2000 server to Debian Sarge with Samba (3.0.10).  Works
nicely.  But apparently there's a Microsoft Access database on this
specific server that people have been using - apparently one of them add
in information in the database, while the rest access the same database to
read it only - apparently people can do that on the old server - i.e. one
person opens it, the rest can open a "read only" copy of it fine.

But now that Samba is serving up the file, only one person can open the
database at a time - the rest gets an "Unable to lock file" error message
- I assume this is because Samba only allows one person to use the file at
a time and blocks other people to open the database as read only - how to
allow Samba to give access to this specific file but read only?

Thanks very much for your help in advance!

Cheers - Piers
