i used samba with subnet browsing years ago
it dont worked with tun interfaces, it must have been tab interfaces
additional right samba setup
times may changed, samba and openvpn changed
but simply try it does not cost anything


my setup was


bdc--internalnet--firewall--(tunnel)--firewall--internalnet--pdc

i had samba on the firewalls to bind to tab tunnel interfaces
as wins proxy
the pdc was the wins server, bdc as wins proxy and directed browsing to
pdc, all clients did got well configured parameters per dhcp
additional there was a working dns which matched dynamicly wins

anyway times may change , and there are better solutions now
but this one worked stable an robust

read samba faqs wins and subnet browsing etc


good luck
