I thought to add also a bug for the missing printing support. So we could discuss here what should be implemented how and when!
The first step for me should be the print$ share for the printer drivers. I think since Windows computers generate her by default, also SAMBA 4 should that do rather than it wasn't done in SAMBA 3 (http://wiki.samba.org/index.php/Samba_as_a_print_server#Providing_Printer_Drivers_to_Windows_clients_with_the_.5Bprint.24.5D_share)
Andrew, is there a plan to modify the provisioning to automatically create the shares "print$" and if needed also "printers"?
Sure, but only once we get printing support....
At the moment this has very low priority.
printing is supported in 4.0 now in the same level as before.
