Somewhere along the line, somebody decided to make the 'full name' field

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).
