Chapter 16

Administering NIS+ Passwords

This chapter describes how to use the passwd command from the point of view of an ordinary user (NIS+ principal) and how an NIS+ administrator manages the password system.

Tip - Some NIS+ security tasks can be performed more easily with Solaris Management Console tools if you have them available.

Note - NIS+ might not be supported in a future release. Tools to aid the migration from NIS+ to LDAP are available as of the Solaris 9 release. For more information, see System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) and visit NIS+ End-of-Feature (EOF) Announcement FAQ.
