Assuming that NIS passwords are kept in /etc/passwd on NIS server try

# passwd -r files -F /etc/passwd
# cd /var/yp
# make passwd

Hi jerry,
On a client root
could easily be spoofed since NIS has no method of authenticating if this is a
validated client/user/root user. If your NIS master is an HP-UX 10.x, root can use the 'expire password'
functionality in the password field by blanking this field out in the
respective NIS password file.

EXAMPLE:
juser::749:20:Jerry user:/home/juser:/usr/bin/ksh

Or if you are using an HP-UX 11.x, you can change the users password on the
master using the HP-UX 10x method or use the command:

/usr/bin/passwd -r files -F /etc/passwd [username]

If you are using a non-standard password file, other than (/etc/passwd), just
be sure to replace the proper path and name of the password file in the
previous command.
