79a1b8d9e2 Implement incremental passwd database updates. This is done by ading a '-u'
option to pwd_mkdb and adding this option to utilities invoking it.
Further, the filling of both the secure and insecure databases has been
merged into one loop giving also a performance improvemnet.
Note that I did *not* change the adduser command. I don't read perl
(it is a write only language anyway).
The change will drastically improve performance for passwd and
friends with large passwd files. Vipw's performance won't change.
In order to do that some kind of diff should be made between the
old and new master.passwd and depending the amount of changes, an
incremental or complete update of the databases should be agreed
upon.

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.

b0ac1967ba Add a little info to this man page at the start so it doesn't
appear that ALL the passwd command does is change a users Kerberos
password, since that is incorrect.

Actually, this man page needs a good overhaul to better reflect systems
that don't have Kerberos installed.

e075ffc9a7 1) Fix local_passwd to co-operate with dual-personality crypt(3).
Changing a local passwd will now keep the encryption type that
   was originally used to encrypt the password, so folks adding DES
   to their systems will not be irritated/confused by having MD5'ed
   passwords in their master.passwd. Coming later is an option to
   allow the user to choose the encryption type.

2) Fix a bunch of compiler warnings announced by turning on -Wall.
   I did not get them all, that will come a bit later.

44440ae8b2 Small tweak: the 'is exisating password an empty string' check isn't
quite right. (Thic causes you to get prompted for an 'Old Password' when
changing someone's NIS password even if your password isn't set yet.)
Do it like local_passwd.c does.

b62f3dc428 Bug fix: use the use_yp() function in the chpass(1) code to determine
correctly whether a user is local or NIS (or both, or neither). If you
have a user that exists locally but not in NIS, passwd(1) could get
confused and try to submit the password change to NIS. (Fortunately,
yppasswdd is smart enough to spot the error and reject the change.)

1724847d45 Whoops: getnewpasswd() always says "Changing local password for foo".
Change things slightly so this message says "local" or "YP" as needed
so we can use it for both NIS and local password changes without
confusing people.

a7aa6bd1ea getnewyppasswd() in yp_passwd.c doesn't generate correct encrypted
password strings when DES isn't used; somehow the encrypted password
is corrupted and it winds up containing control chars, which yppasswdd
subsequently rejects. This breaks yppasswd on non-DES FreeBSD systems
using NIS.

Fix: scrap getnewyppasswd() entirely and use getnewpasswd() from
local_password.c, since it already works properly and is virtually
identical to getnewyppasswd() anyway. (Wish I'd noticed this sooner.)

This fixes a problem just reported on comp.unix.bsd.freebsd.misc.

8a363d18bb Patch to fix PR #518. In a system with no NIS, passwd will complain
that it can't contact an NIS server when asked to change the password
of an invalid user. It should say 'unknown user' instead.

The fix is to check for the _PW_KEYYPENABLED flag in the password
database and only roll over into the yppasswd stuff if the flag
is enabled (this means passwd will not behave as yppasswd if
there are no +::::::::: entries in /etc/master.passwd). If
NIS is enabled but the user says 'passwd -l foouser' where
foouser exists in the NIS maps, but not in /etc/master.passwd,
we also say 'unknown user.' This is so we don't outsmart ourselves:
specifying the -l flag restricts passwd to the local password database
even if NIS is enabled.

This change should probably be merged into 2.1.

01ed185959 Changed passwd's Makefile to use the built-in LINKS mechanism to create
the symlinks for yppasswd & friends (we still can't use hard links
because passwd is installed immutable). This would have been simpler
if the LN_FLAGS variable hadn't chosen to wait until now before leaping
out of the /usr/share/mk directory and biting me in the ass. (And thus,
I was enlightened.)

7506dfc15e Changed passwd/yppasswd's Makefile to create all symbolic links instead
of hard links: since passwd is installed immutable, an attempt to make
a hard link to it during a 'make install' would fail. I didn't notice
this conflict because my /usr directory is an NFS filesystem mounted from a
SunOS server, so the special file mode flags had no effecti when I tested
everything on my machine. Live and learn.

9e32e2330f Obtained from: The NYS project
This is the first round of changes to incorporate YP server functionality
into FreeBSD. This particular change allows passwd to change either the
local or NIS password, as well as the NIS GECOS and shell information.

Essentially, I've taken passwd(1) and yppasswd from the yppasswd-0.5
distribution (which is part of the NYS project -- a project to provide
a GNU GPL'ed suite of NIS tools) and rammed them into each other
at high speed. I've tried my best to make this co-exist with the
Kerberos stuff, but since I don't run Kerberos I don't have an easy
way to verify that it all works. If you choose any Kerberos flags
then the YP checks should be bypassed, but that may not be enough.
I'll modify it some more if it turns out I broke something. For now,
support for localand NIS passwords is pretty solid:

- If you simply type 'passwd,' the program checks to see if you exist
  in the local pwd.db database. If not, you get bounced to YP.

- If you try to force local functionality with the -l flag and you
  don't exist locally, you get an error.

The -y flag can be used to force YP functionality. -f and -s let you
change your full name and shell (respectively). -f *and* -s let you
change all of your 'account information.'

ypchfn, ypchsh, yppasswd and ypchpass are all links to passwd.

0cd34073b2 Kill old Kerberos password-changing support:
1) It was export-controlled.
2) It used some ad-hoc protocol invented by Berkeley in ignorance of the
   standard MIT distribution's way of doing it (which makes it useless
   to most people).

This should be fixed once we have `kadmin'/`kadmind'.
