[SLUG] umask file permissions with samba

[Peter Rundle <peter@xxxxxxxxxxxxxxxxxx>]

Sluggers,

I've set up a samba server for a small office. The client computers are 
windoze95/8. Each person logs into
windoze with their own user account and I've used user level security on 
the samba server and created
the same users under linux. I've placed all the users in the same group 
so that they can share files.
However when one of them creates or saves a file over the share it is 
saved with rw-r--r-- permissions.
How can I configure samba so that the group has write permission. 
Normally this would be set by the
umask of 002 (right?)

TIA's

Pete
