[Samba] Samba printing problem with samba 4.15.X.

[Peter Varkoly]

Hi List,

on samba-4.15.2 and 4.15.5 I've 2 problems with printig with CUPS:

1. load printers = yes does not work. The printers are not loaded.
2. Creating for all printer a section and the GPO described in 
https://wiki.samba.org/index.php/Setting_up_Automatic_Printer_Driver_Downloads_for_Windows_Clients 
the domain user Administrator can acces the printers but all other 
domain users get an error message that the printer can not be found.

OS is openSUSE Leap 15.3
samba-ad is self built with internal krb.
Here is my smb.conf:
--------------------------
[global]
netbios name = admin
realm = DNS.DOMAN
workgroup = DOMAIN
dns forwarder = 172.16.0.5
server role = active directory domain controller

winbind enum users = Yes
winbind enum groups = Yes

[generic-postscript]

[gps]

printer name = gps
hosts allow = 172.16.2.0/27
