Name
       yppasswd - change password in yellow pages (YP) service.

Syntax
       yppasswd [ name ]

Description
       The  command lets you change your password in the yellow pages (YP) map, a network data base service.  Only you or the superuser can change
       your YP password.

       When you enter the command, the program prompts you for the old password and then for the new password. Note that  the  passwords  are  not
       displayed on the screen.

       Next,  the  program asks you for the new password again, to verify that you have typed it correctly.  If you do not type the passwords cor-
       rectly, you will receive an error message after you enter the new password.

       Your new YP password must meet one of the following requirements:

	  o It must be a combination of at least six alphanumeric characters, or

	  o It must be a minimum of four characters, with at least one being non-alphanumeric, such as a control sequence.
       The command does not change the YP password.  This command only changes the local password file and not the YP master password  file.   See
       Chapter 3 of the Guide to the Yellow Pages Service for further information.

Diagnostics
       Please use a longer password
       Your new password does not meet the minimum length requirement.

       Mismatch- password unchanged
       You misspelled your new password or its verification.

       couldn't change passwd
       Your new password can not be activated. It must be different from your old password and your login name.

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.
