I am using Samba 3.6.6 on Debian Wheezy.

I want to be able to change www files on my dev server using my macbook. So I setup samba and made a share for the /var/www directory.

I added the users bart & root to samba to connect. And connect using command K and then smb:// (my samba server).

As apache uses www-data as a user and group for the www files I use force user and force group in samba to prevent errors in the rights.

However it does force the group www-data, but doesn't force the user. Every file I create is being owned by root in the group www-data.

To seek for errors I tailed the logs in /var/log/samba and only found an error in the log.smbd when restarting the samba service. See the log here:

smbd version 3.6.6 started.

And here is my smb.conf:

    create mask = 0700
    printable = Yes
    print ok = Yes
    browseable = No

    comment = Printer Drivers
    path = /var/lib/samba/printers

    comment = www
    path = /var/www/
    valid users = bart, root
    admin users = bart, root
    write list = bart, root
    force user = www-data
    force group = www-data
    read only = No

I even tried adding www-data to the valid users as well as the admin users and the write list. This of course did not have any effect.

Can you help me out? Thanks in advance!

I think that in this case the option admin users overrides the option force user. So when you connect as the user bart to the share www it will be granted administrative privileges on it and all file operations will be done under super-user root.

Try to remove the user bart from admin users list, reload the service and verify its behavior again.

Finally, it's worth to mention that the user bart has to have write permissions on that directory. You can use ACLs to achieve that or put the user to the www-data group.

Thanks I would like to vote up, but unfortunately not enough points scored yet ;) It was indeed the admin users which was in the way. I removed those and the issue was gone! – BonifatiusK Sep 23 '13 at 10:37
