Status changed to 'Confirmed' because the bug affects multiple users.

[Nick Semenkovich (semenko)]

I also had this issue, though only after removing samba4 (aptitude purge samba4) and reinstalling, due to bug #1096791

The same error appears 20 or so times during the install, although samba4 appears to be running:

Error loading module '/usr/lib/x86_64-linux-gnu/samba//vfs/acl_xattr.so': /usr/lib/x86_64-linux-gnu/samba//vfs/acl_xattr.so: cannot open shared object file: No such file or directory

Installing:
apt-get install samba-vfs-modules
solved this problem for me.
