NIS (or both, or neither). Also add support for -l and -y flags to
force behavior to local or NIS. use_yp() also goes out of its way to
retrieve the correct password database information (local or NIS)
depending on what the situation since getpwent() & co. can't
necessarily be trusted in some cases.
Also document new flags in man page.
and graft it into chpass.
Chpass can now tell when it's being asked to operate on an NIS
user and it displayes the appropriate message in the editor
template ("Changing NIS information for foo"). After the changes
have been made, chpass will promte the user for his NIS password.
If the password is correct, the changes are committed to yppasswdd.
Hopefully, this should make NIS more transparent to the end user.
Note that even the superuser needs to know a user's password before
he can change any NIS information (such is the nature of yppasswdd).
Also, changes to the password field are not permitted -- that's what
yppasswd is for. (The superuser may specify a new password, but
again, he needs to know the user's original password before he can
change it.)
restricted. Am I the only one who sees the absurdity of having chfn be
a link to chpass, and then denying users permission to use chpass to
change their full names?
Of course, chpass has a much more severe bug in it, which is that it
allows users to change their password database info without first
asking them for their password. I hope to fix this at some point
so that I can merge ypchpass, ypchfn, ypchsh and chpass into one
program (password authentication is required for changing NIS data).
