1) passwd backend doesn't support extra fields. There's just no way to
do what you want with it.

2) Modifying /etc/passwd the way you did could easily break other
programs. Using something like chsh to modify /etc/passwd could drop the
fields you added. I wouldn't recommend doing it.

3) You should probably be using userdb passwd-file. I guess you could
simply do userdb passwd-file { args = /etc/passwd } and the above
modification would work, but because of 2) I'd recommend using a
different file and figuring out some way to keep it in sync
with /etc/passwd.
