As Samba is trying to emulate a Microsoft Active Directory domain, we
are limited by the ports that Microsoft uses.

Agreed, but, again we are limited by what Microsoft uses.

Not in AD and I cannot really remember seeing anything to do with AD
that suggested using other than the ports Microsoft uses.
