Solaris Naming Administration Guide

Adding Compatibility With +/- Syntax

You can add to your nsswitch.conf file compatibility with the +/- syntax sometimes used in /etc/passwd, /etc/shadow, and /etc/group files.

Note -

Users working on a client machine being served by an NIS+ server running in NIS compatibility mode cannot run ypcat on the netgroup table. Doing so will give you results as if the table were empty even if it has entries.

See the switch file chapter of Solaris Naming Setup and Configuration Guide for step by step instructions on adding +/- semantics to an nsswitch.conf file.
