To allow domain controllers to create machine trust accounts on-the-fly in Samba, you will need to set the allow trusted domains parameter in the smb.conf configuration file to yes.
The allow trusted domains parameter controls whether Samba allows trusted domains to create machine trust accounts on-the-fly. When set to yes, Samba will allow trusted domains to create machine trust accounts on-the-fly. When set to no, Samba will not allow trusted domains to create machine trust accounts on-the-fly.
To set the allow trusted domains parameter in the smb.conf configuration file, open the file in a text editor and add the following line:
allow trusted domains = yes
Save the file and restart the Samba service for the changes to take effect.
By setting the allow trusted domains parameter to yes, you can allow domain controllers to create machine trust accounts on-the-fly in Samba. It's always a good idea to carefully review the documentation and use the appropriate options and settings when working with Samba. This will help ensure that your Samba configuration is set up correctly and that any problems are detected and addressed.
