System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP)

Password Files and Namespace Security

For security reasons, follow these guidelines.

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. When you use either the Service Management Facility or the ypstart script to start the NIS service, the correct directory option is set according to the configuration specified in your Makefile.

Note –

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