Hi, I would like to create an external outgoing trust from a Samba4 AD domain to an old Samba3 NT4 domain. I'm getting this error: root@:~# samba-tool domain trust create OLDDOMAIN --type=external --direction=outgoing -Ugravasio LocalDomain Netbios[NEWAD] DNS[newad.modiano.com] SID[S-1-5-21-123456789-1234567556-3271483883] ERROR: Failed to find a writeable DC for domain 'OLDDOMAIN' Running the command with -d10 says at the end: finddcs: NBT <1c> response 0 at '172.16.xx.xx' finddcs: performing CLDAP query on 172.16.xx.xx finddcs: No matching CLDAP server found I wonder if this type of trust is supported at all by Samba? Thanks Giuseppe
