Samba permissions problem

Please help me .....

I have this issue on my hand,

I'm trying to make a directory for my group that everyone can read write and modify eachothers files. But in order to access it you must be a user on the server.

So this one works

[PUBLIC]
path =/fileshare
public = yes
only guest = yes
writable = yes
printable = no

But problem with above config is that anyone can get to the directory with out authenecating,
[PUBLIC]
path = /fileshare
valid users = user user
public = no
writable = yes
printable = no
create mask = 0765

This one creates file with user permissions as and we can not edit eachothers files...


Any Ideas ???

to edit each other´s files, you need to setup group permissions. i.e. make a new group, add all users that share these files to this group ("netusers" from now on).
then
chown -R .netusers /fileshare
and setup two things for samba in /etc/smb.conf:
- create mask should be 775 or 770
- force group = netusers

this is untested, but should work.
