Description Stefan Metzmacher 2024-04-05 12:02:19 UTC 
winbindd needs to try nmb/dgram requests in order to implement 
wbint_DsGetDcName() for dcesrv_netr_DsRGetDCName_base_call(), when the
client provides only an NT4 domain name.

In the AD DC case process_dc_netbios() falls back to name_status_find()
and only returns NT4 data, even if the request is for an ad trust.
