Solaris Naming Administration Guide

Password Files and Namespace Security

For security reasons:

For example, the master server password input files could be stored in a directory such as /var/yp, or any directory of your choice, as long as the file itself is not a link to another file and is specified in the Makefile. The /usr/lib/netsvc/yp/ypstart script automatically sets the correct directory option according to the configuration specified in your Makefile.

Note -

In addition to the older Solaris 1.x version passwd file format, this implementation of NIS accepts the Solaris Release 2 passwd and shadow file formats as input for building the NIS password maps.
