[nzlug] Samba file creation ownerships.

[Andrew Bruce]

Hi,

I'm trying to setup something (tricky I think - unless I'm going about 
this the wrong way...)


I've got a folder called storage on my server which a flatmate and I use 
to keep a bunch of files that we want to be accessible to both of us, 
and the general flat.  I've created the folder [storage], and assigned 
it nobody:store ownership (I created the UNIX group store), and 
rwxrwxr-x permissions.

I've shared this folder through Samba (as it needs to be Linux and 
Windows accessible, as we both dual boot, and one other flatmate is 
Windows only) and allowed guest access to the folder, so that the other 
flatty can browse but not write files and this works.  The Samba setup 
also allows us two users to be able to create files and directories, 
which are created with the correct permissions (774) and this works well. 

The issue is that when user1 (or user2) creates the files, the machine 
gives the group ownership of the files to the group users (as in 
user1:users).  This becomes an issue, because I have other users who 
have Samba accounts on the machine and are users group members who can 
then play with files, or write files into directories created.

What I need to be able to do is to set the group ownership of any 
directory or file created by user1 and user2 to the store group.

I tried the force group = store option, but this also happens to force 
the guest user to 'appear' as part of the store group, allowing them to 
do whatever they want.


Any suggestions, or alternative ways to set this up?  I would prefer not 
to have to use the 'admin users' option in the smb.conf file, as I would 
rather just be able to add the user to a UNIX group when they are 
created and they instantly have the right permissions.

Thanks,

Andrew Bruce
