a041dfad25 Change the prompt for the office location field from "Location:"
to "Office Location:" to disambiguate what is expected.  Add a note
to the man page to indicate that the office location and office phone
fields are concatenated and printed with the heading "Office:" by
finger(1).  Swap the order of the home and office phone fields in the
man page to match the order of the fields in the editor.

If any programs interact with chpass(1) and expect "Location:" instead
of "Office Location:" as the prompt, either this change will have to be
reverted or the other programs will have to be changed.

Add functionality for support for more than 4 subfields within gcos. chsh,
chpass etc did not parse beyond the 4th field previously and so truncated
gcos on updating the database.

0587e3a417 pw_scan() was being used to convert a string into a struct passwd, with
an auto stack variable that was about to disappear.  It broke with some
nis passwd changes because of a gethostbyname() call that uses a fair bit
of stack..  This was a timebomb waiting to go off at any time and could
have been causing subtle corruption for a while.

AARGH!!

This is HIGHLY reccomended for 2.2 and presumably 2.1.6

366982a550 Add new option to chpass: -e "expire" ; change the account expire time
from a script as if it was done in the interactive editor.

When reassembling the gecos string, trim any excess trailing commas, they
look ugly in the passwd file. :-)

Have a simple Makefile tweak to prevent mortal users from changing their
fullname.  As ISP's we have seem some real bizzare stuff here..

When decoding the change/expire string, allow the month number as a
synonym for the name of the month.. (ie: 1 as well as Jan or January)
Note that using numbers means there's a chance that you can get bitten
if you're not used to the American DD-MM-YY order.

c2dfe9fe01 Merge in changes to support the new rpc.yppasswdd(8) and fix a few bugs.
In passwd(1):

- Gut most of yp_passwd.c and leave only a few things that aren't common
  to pw_yp.c.

- Add support for -d and -h flags to select domains and NIS server hosts
  to use when updating NIS passwords. This allows passwd(1) to be used
  for changing NIS passwords from machines that aren't configured as
  NIS clients. (This is mostly to allow passwd(1) to work on NIS master
  servers that aren't configured as clients -- an NIS server need not
  necessarily be configured as a client itself.)

  NOTE: Realize that having the ability to specify a domain and hostname
  lets you use passwd(1) (and chpass(1) too) to submit update requests
  to yppasswd daemons running on remote servers in remote domains which
  you may not even be bound to. For example, my machine at home is not
  an NIS client of the servers on the network that I manage, yet I can
  easily change my password at work using my FreeBSD box at home by doing:
  'passwd -d work.net.domain -h any.nis.server.on.my.net wpaul'. (Yes,
  I do use securenets at work; temporarily modified my securenets file
  to give my home system access.) Some people may not be too thrilled
  with this idea. Those who don't like this feature can recompile passwd(1)
  and chpass(1) with -DPARANOID to restrict the use of these flags to
  the superuser.

  (Oh, I should be adding proper securenets support to ypserv(8) and
  rpc.yppasswdd(8) over the weekend.)

- Merge in changes to allow root on the NIS master server to bypass
  authentication and change any user's NIS password. (The super-user
  on the NIS master already has privileges to do this, but doing it
  through passwd(1) is much easier than updating the maps by hand.)
  Note that passwd(1) communicates with rpc.yppasswdd(8) via a UNIX
  domain socket instead of via standard RPC/IP in this case.

- Update man page.

In chpass(1):

- Fix pw_yp.c to work properly in environments where NIS client
  services aren't available.

- Use realloc() instead of malloc() in copy_yp_pass() and copy_local_pass().

- Fix silly bug in copy_yp_pass(); some of the members of the passwd
  structure weren't being filled in correctly. (This went unnoticed
  for a while since the old yppasswdd didn't allow changes to the
  fields that were being botched.)

- chpass(1) now also allows the superuser on the NIS master server to
  make unrestricted changes to any user's NIS password information.

- Use UNIX domain comm channel to rpc.yppasswdd(8) when run by the
  superuser on the NIS master. This allows several new things:

   o superuser can update an entire master.passwd.{byname,byuid} entry
   o superuser can update records in arbitrary domains using -d flag to
     select a domain (before you could only change the default domain)
   o superuser can _add_ records to the NIS master.passwd maps, provided
     rpc.yppasswdd(8) has been started with the -a flag (to do this,
     the superuser must force NIS operation by specifying the -y flag
     to chpass(1) along with -a, i.e. 'chpass -y -a 'foo:::::::::')

- Back out the 'chpass -a <new password entry> breaks with NIS' fix
  from the last revision and fix it properly this time. The previous
  revision fixed the immediate problem but broke NIS operation in
  some cases.

- In edit.c, be a little more reasonable about deciding when to
  prevent the shell field from being changed.

  Submitted by Charles Owens <owensc@enc.edu>, who said:

  "I made a minor (one-line) modification to chpass, with regards
   to whether or not it allows the changing of shells.  In the 2.0.5 code,
   field changing follows the settings specified in the "list" structure
   defined in table.c .  For the shell, though, this is ignored.  A quick
   look in edit.c showed me why, but I don't understand why it was written as
   such.  The logic was

        if shell is standard shell, allow changing

   I changed it to

        if shell changing is allowed (per table.c) and it is a standard shell
             OR if uid=0, then allow changing."

   Makes sense to me.

- Update man page.

367157222f Take the ypchfn/ypchsh stuff that was removed from passwd
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.)
