[Samba] vfs_shadow_copy2 woes

[Matthias Leopold]

Hi,

finally everything is working fine on my Samba 4.6 AD Domain member 
server after _exactly_ following 
https://wiki.samba.org/index.php/Setting_up_a_Share_Using_Windows_ACLs 
(no more fiddling with acl_xattr:ignore system acls = yes, thanks 
Rowland Penny).

Next thing i wanted to try is vfs_shadow_copy2 (with LVM snapshots: 
https://wiki.samba.org/index.php/Rotating_LVM_snapshots_for_shadow_copy). 
But as soon as i enable "vfs objects = shadow_copy2" for a share i can't 
administer file permissions ("Security") via Windows (as "Domain Admin") 
anymore. This happens even without any snapshots (it's the same when 
there are snapshots).
Why?

I tried disabling SELinux, no avail. I'm attaching some "log level = 9" 
logs and hope someone can enlighten me.

Thanks
Matthias
