Kerberos runs as a service on the Linux operating system. If any changes are made to Kerberos, such as any administrative configuration changes or if Kerberos has been restored from backup, the service must be restarted before the changes can take effect. Stopping or restarting Kerberos on a Linux server requires the Terminal application. Only the root user can start and stop system services.
