In this release, naming services configuration is managed by the Service Management Facility (SMF). What this change means is that the SMF repository is now the primary repository for all naming services configuration and you no longer modify a specific file to configure naming services. To make the configuration persistent, you must enable or refresh the appropriate SMF services.
If no network configuration exists after an installation, naming services default to files only behavior rather than nis files. To avoid potential configuration issues, make sure that the svc:/system/name-service/cache SMF service is enabled at all times. For more information, see Chapter 1, About Naming and Directory Services in Working With Oracle Solaris 11.3 Directory and Naming Services: DNS and NIS.
