[Samba] FW: Unable to upload printer drivers (confirmed up to samba 4.7.1)

[L.P.H. van Belle]

Hai Manu, 

Small update. After updating my samba 4.6.9 to 4.7.1 ( own packages ) 
The result is the same fail..., but i do have a success also. Huh? 

The following happens. 

Test1 	If you use a windows ( orignal by windows supplied ) driver. 
Result1	Fail. 
Sample from the samba log:
[2017/11/07 13:22:42.701653,  0] ../source3/printing/nt_printing.c:1145(move_driver_file_to_download_area)
  move_driver_file_to_download_area: Unable to rename [x64/{FBEB1F49-581B-4460-BE69-5BCE02C76063}/hp_xps_pcl6_color_a_hwcp] to [x64/3/HP_XPS_PCL6_Color_A_HWCP]: NT_STATUS_OBJECT_NAME_NOT_FOUND
[2017/11/07 13:22:42.701798,  0] ../source3/rpc_server/spoolss/srv_spoolss_nt.c:8599(_spoolss_AddPrinterDriverEx)
  _spoolss_AddPrinterDriverEx: move_driver_to_download_area failed - WERR_ACCESS_DENIED 


Now Test2. 
I downloaded the HP universal 6.5 driver from the HP website. 
(link: https://support.hp.com/us-en/drivers/selfservice/UPD/4157320/model/4157320 ) 
Extracted them to a folder and, installed the driver without any problem from my windows 10 pc. (x64) 
Result, Success.. 

The one thing i noticed in the windows driver. hp_xps_pcl6_color_a_hwcp
HP XPS pcl .... ? 

Where this "bug" exact resists, i dont know. 
But as far i know the HP Universal is not packaged, so maybe thats still related to (close) bug 
https://bugzilla.samba.org/show_bug.cgi?id=12993
Or 
https://bugzilla.samba.org/show_bug.cgi?id=12761 
but thats my guess for now. 


Sofar,

Greetz,
