The nsswitch.conf file is the configuration file for name-service lookups. This file determines the following information:
The databases within the Oracle Solaris environment to use for name-service lookups
The order in which the databases are to be consulted
Some data services require that you direct “group” lookups to “files” first. For these data services, change the “group” line in the nsswitch.conf file so that the “files” entry is listed first. See the documentation for the data service that you plan to configure to determine whether you need to change the “group” line. The scinstall utility automatically configures the nsswitch.conf file for you. If you manually modify the nsswitch.conf file, you must export the new nsswitch configuration information.
