[L.P.H. van Belle]

Hai, 
 
Im working on the print server, samba cups, and so fare, looks ok.
 
but im seeing messages like.

  _spoolss_AddPrinterDriverEx: level 8 not yet implemented

im use-ing samba with the following settings:  (  basic member settings with  )
load printers = yes
rpc_server:spoolss = external
rpc_daemon:spoolssd = fork
spoolssd:prefork_min_children = 15           # Minimum number of child processes
spoolssd:prefork_max_children = 75          # Maximum number of child processes
spoolssd:prefork_spawn_rate = 25            # Start (fork) x new childs if one connection comes in (up to prefork_max_children)
spoolssd:prefork_max_allowed_clients = 200  # Number of clients, a child process should be responsible for
spoolssd:prefork_child_min_life = 60        # Minimum lifetime of a child process (60 seconds is the minimum, even a lower value has been configured )
 
I did setup the printer operator privileges. (https://wiki.samba.org/index.php/Samba_as_a_print_server#Granting_print_operator_privileges)
( thanks Rowland and Stephane, for there help, now it works great. ) 
I did setup the shares https://wiki.samba.org/index.php/Setup_and_configure_file_shares#Change_permissions_on_folder_of_a_share 
 
I do need to setup the trusts https://wiki.samba.org/index.php/Samba_as_a_print_server#Setting_up_a_GPO_for_trusting_printer_drivers
 
How mature is this new spoolssd? 
since im reading here : http://wiki.samba.org/index.php/Samba_as_a_print_server 
Note: Some features of spoolssd were broken before 4.0.17 and 4.1.7. That's why it is recommended to use at least this versions! 
 
4.1.7 ? does the next release has good fixed for spoolssd ? 
 
and how is the experiance at others with samba and cups printing, with the new spoolssd. 
 
any tips or advices is apreciated. 
 
Thanks,
 
Louis
