Yes, I know. Unfortunately, it is possible with our current samba3/OpenLDAP  
setup, so it should preferrably be possible with samba 4 as well.

That's good to know, thanks!

It's the same:

root at test-samba4:~# smbd -b | grep icon -i
   HAVE_ICONV_H
   HAVE_ICONV
   HAVE_ICONV_OPEN
   HAVE_NATIVE_ICONV

Thanks for your answer!
