[Samba] unix_primary_group=yes together with vfs objects=acl_xattr not working
Hello all, we want to change the configuration of our Samba domain member file servers to use unix_primary_group=yes 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 Klaus

On the Linux Samba server I have a group with this GID. The name of this group shows up in the smbstatus output. New files are created with this GID, but only if vfs objects = acl_xattr is commented out. We access the file servers from Windows clients via SMB and from Linux clients via NFS. I want to use private user groups on Ubuntu to change the umask to 002 on login automatically on Ubuntu (Explained in /etc/login.defs). Therefore every user requires its own primary group with the same name of the user. I know that it is not possible to have groups with the same name in AD, so I want to use the GID (number) UNIX attribute and resolve it to the existing (private user) group on the Linux server. Everything works as expected but only without the vfs objects = acl_xattr line in smb.conf.
