[Samba] Samba4 - Printer Drivers install fails

[Julien TEHERY]

Hi,


I have a question about printer drivers management in Samba4 (Samba 
version 4.7.6, Ubuntu 18)

I use MMC to add new drivers to an existing cups printers, and some of 
them are simply refused.

I know the samba4/cups server is operationnal as i'm able to add new 
printers or drivers to it through MMC.

I guess it's not a permission problem on the server as i perform the 
operation as domain administrator and i'm able tu upload some drivers.

The setup only fails for specific drivers (x64, type3 - user mode)  but 
i d'on't know why.

I precise i upload those drivers from a 64 bits windows. I even tried 
this parameter on cups's  smb.conf :

  spoolss: architecture = Windows x64


I also read the whole page from 
https://wiki.samba.org/index.php/Setting_up_Automatic_Printer_Driver_Downloads_for_Windows_Clients#32-bit_and_64-bit_Drivers


in MMC, Error are:

- first popup with "Access denied" => weird answer as i'm able to upload 
other drivers

- second popup ends with error 0x00000578


in Samba4/cups server logs, we have:

  mo[2019/11/21 11:57:41.151380,  0]

On the server, permissions are:

drwxrwxr-x+ 2 administrator domain users  4096 nov.  21 10:04 3/


Any idea of what the problem is?


The printer drivers are:

- impxeroxc405        imprimante Xerox Versalink c405

- impxeroxc8030      imprimante Xerox Altalink c8030
- lexxc4140              imprimante Lexmark XC 4140
