Hello all,

we want to change the configuration of our Samba domain member file 
servers to use


After some experiments I was able to get it to work, but only with

vfs objects = acl_xattr

commented out.

With acl_xattr enabled the primary group is still displayed correctly in 
the output of smbstatus, but new files are not created with with this 
primary group. The created files have the default group 'users' instead.

Is it a  bug in the acl_xattr module?

I used the latest Ubuntu server version for testing:

Samba version 4.10.7-Ubuntu
