Configuring the Name Service Switch
Syntax of the nsswitch.conf File
Chapter 6 273
If a line beginning with one of the lookup_types does not exist in the
/etc/nsswitch.conf file, the default Name Service Switch
configuration for that type of information is used. If the
/etc/nsswitch.conf file does not exist, the default configuration is
used for every type of information. The default Name Service Switch
configuration is described in “Default Configuration” on page 275.
