YPPASSWD(1)

NAME
yppasswd - change login password in yellow pages

SYNOPSIS
yppasswd [ name ]

DESCRIPTION
Yppasswd changes (or installs) a password associated with the user name (your own name by default) in the yellow pages. The yellow pages password may be different from the one on your own machine.

Yppasswd prompts for the old yellow pages password and then for the new one. The caller must supply both. The new password must be typed twice, to forestall mistakes.

New passwords must be at least four characters long, if they use a sufficiently rich alphabet, and at least six characters long if monocase. These rules are relaxed if you are insistent enough.

Only the owner of the name or the super-user may change a password; in either case, you must prove you know the old password.

BUGS
The update protocol passes all the information to the server in one rpc call, without ever looking at it. Thus, if you enter your old password incorrectly, you will not be notified until after you have entered your new password.
