Modifying the name service switch

To change to a switch file, follow these steps.

1. Become superuser.

2. Copy the alternate file appropriate for the machine's naming service over the nsswitch.conf file.

   NIS+ Version (done automatically for you by NIS+ scripts)

   client1# cd /etc

   client1# cp nsswitch.nisplus nsswitch.conf

   NIS Version

   client1# cd /etc

   client1# cp nsswitch.nis nsswitch.conf

   Local /etc Files Version

   client# cd /etc

   client# cp nsswitch.files nsswitch.conf

3. Reboot the machine.

   The nscd naming service cache daemon caches switch information. Some library routines do not periodically check the nsswitch.conf file to see whether it has been changed. You must reboot the machine to make sure that the daemon and those routines have the latest information in the file.

In order to use LDAP naming services, you must also properly configure all LDAP client machines, in addition to modifying the nsswitch.conf. See for Chapter 16, Client Setup (Task) more information.
