Try if you cann resolve the SRV-records in both directions from both
DCs. On the Linux DC do:
host -t srv _ldap._tcp.samba.local

host -t srv _ldap._tcp.win.local

On the Windows DC you can use "nslookup".
Only if both DCs can resolve the SRV-records you can establish the
trust. I normaly use a bind9 as a DNS-Proxy.I did a tutorial on the 2019
SambaXP about trusts here you will find the handout, it will describe
how to set up a DNS-proxy
