samba - Jul 2013 - Samba 4 not honoring setgid

I'm running Samba 4.0.7 on CentOS 6.4 as a AD DC with s3fs.

I have a shared directory with the setgid bit set. From the shell on the
server, new files and directories inherit the group as expected. However,
new items created through samba get the user's primary group instead.

Config for the share is super simple:

[test]
        path = /srv/test
        read only = no


Sounds like a bug. Has any one else experienced this?

Hi
openSUSE 12.3 DC 4.0.7 also tested with latest git

Not sure what /srv/test has but am guessing that you have set chmod g+s?

If so, I can reproduce what you see. The g+s is ignored when accessed on
a cifs mounted share and instead the primaryGroupID is used.
