[Samba] Set printer driver on 4.16.2 does not work

[Peter Varkoly]

Hi,

I have problem to set the printer driver with rpc (resp  cupsaddsmb) 
with 4.16.2. The same way has worked on 4.15.5:
I've tried it as Administrator and as user with SePrintOperatorPrivilege 
privilegs as member of the group "Print Operators".

====
rpcclient printserver -N -A /tmp/01c1c62ebd2ec -c 'adddriver "Windows NT 
x86" 
"pr1:pscript5.dll:pr1.ppd:ps5ui.dll:pscript.hlp:NULL:RAW:pscript5.dll,pr1.ppd,ps5ui.dll,pscript.hlp,pscript.ntf"'
result was WERR_NETNAME_DELETED

The ad Server is a samba-4.16.2 too.
The printserver confiugration is:
=================================================
[global]
workgroup = PRICSKE

bind interfaces only = yes

The ad-server configuration is:
=================================================

Do you have any hints for me?

Thanks
