Which command can verify the domain configuration for Samba?

The command that verifies the domain configuration for Samba is testparm. This utility checks the Samba configuration files for syntax errors and validates the settings defined in smb.conf. By running testparm, administrators can see the effective configuration that Samba will use, which includes information related to domain settings, shared resources, and security contexts. It outputs the parsed configuration and highlights any misconfigurations, which is crucial when setting up or maintaining a Samba domain.

Using testparm before starting the Samba service or when troubleshooting connection issues ensures that the configuration is correct and that Samba is properly set up to interact with domain services. It effectively serves as a tool for administrators to confirm that the Samba server will behave as expected in the mixed environment.
