This is what I would expect on a DC where samba4 was self compiled, the 
references to libnss_winbind in /lib/i386-linux-gnu are symbolic links 
to the actual files in /usr/local/samba/lib

And here, the first one appears to be a symbolic link to the second, 
which appears to be another symbolic link to a file that appears to have 
nothing to do with the files you compiled in /usr/local/samba.

Could these be the remains of the previous samba install ?
Try renaming them and then create the symbolic links as per the VM, see 
here for more info:
