To Tell Users How to Use yppasswd
• Tell all the users in your NIS domain that they must use
/usr/bin/yppasswd or passwd -r nis instead of the passwd
command when they want to change their login passwords.
• Tell users that, when they want to change their login passwords,
they should do so just before they leave for the day. This will allow
time for the updated NIS maps on the master server to be pushed to
the slave servers.
The yppasswd command is a link to the passwd -r nis command. It
changes the /etc/passwd file on the NIS master server, regenerates the
NIS passwd maps from the updated /etc/passwd file, and then pushes
the NIS passwd maps to the slave servers.
For more information, see the following man pages: yppasswd(1),
yppasswdd(1M), passwd(1), ypxfr(1M), and yppush(1M).
