Require TLS or TLS-PSK encryption. This directive is ignored unless one of services.bacula-fd.director.<name>.tls.enable is true or TLS PSK Enable is set to yes. If TLS is not required while TLS or TLS-PSK are enabled, then the Bacula component will connect with other components either with or without TLS or TLS-PSK
If services.bacula-fd.director.<name>.tls.enable or TLS-PSK is enabled and TLS is required, then the Bacula component will refuse any connection request that does not use TLS.
