NAME
yppasswd - change login password in Network Information System (NIS)
SYNOPSIS
[name]
Remarks
The Network Information Service (NIS) was formerly known as Yellow Pages (YP). The functionality remains the same; only the name has
changed.
DESCRIPTION
changes or installs a password associated with the login name in the Network Information System (NIS). The NIS password can be different
from the one on your own machine. If name is omitted, it defaults to the name returned by (see getlogin(3C)).
prompts for the old NIS password (even if it does not exist), then twice for the new one. The old password must be entered correctly for
the change to take effect. Checks occur to ensure that the new password meets the following construction requirements.
o Only the first eight characters are significant.
o A password can be as few as four characters long if it contains
o at least one special character or
o a mixture of numeric, uppercase and lowercase letters.
o A password can be as few as five characters long if it contains a mixture of
o uppercase and lowercase letters or
o numeric and either uppercase or lowercase letters.
o A password must contain at least six characters if it contains only monocase letters.
All these rules except the first are relaxed if you try three times to enter an unacceptable new password. You cannot, however, enter a
null password.
Only the owner of the name or the superuser can change a password.
The Network Information System password daemon, must be running on the master NIS password server to change NIS passwords. See yppass-
wdd(1M).
WARNINGS
The password update protocol passes the old and new passwords to the master NIS server at once. Thus, if the old NIS password is incor-
rect, no notification is given until the new NIS password is successfully entered.
The password construction rules are different from those of the HP-UX command (see passwd(1)).
The root user's password cannot be changed using or Therefore, root users must change their password in the files database and then recon-
struct the NIS maps using the command. For more information on how to use the command, see ypmake(1M).
