[Samba] Open (obsolete?) ports on Samba DCs

Hi folks,

I just noted that the Netbios ports are active and listening on a Samba 
AD DC with the default configuration. On member servers they don't exist.

I have several domains with mixes of Windows and Linux servers and PCs, 
and I have disabled the old insecure protocols long ago.

Is this by design, or are you supposed to plug them yourself after 

I'm using Samba 4.18.8 everywhere (from Debian Bookworm backports).

Best regards
