usr.bin/chpass: Correct manpage regarding path to temp files

Approved by: blackend (mentor)

Partially revert r367756 (chpass(1) synopsis changes)

Let's have two entries in the synopsis:
- chpass now lists options which can be used for non-NIS-specific
functionalities.
- ypchpass additionally lists the NIS-specific flags.

Technically, it is an artificial distinction, as chpass and ypchpass behave
identically. Nevertheless, it might help navigating the synopsis section.

Replace the -q option to pwd_mkdb with a test for PW_SCAN_BIG_IDS in
the environment. This allows big ID warnings to be suppressed for
vipw and chpass as well.

Since the environment variable test is only performed for callers
of pw_scan() that do not set pw_big_ids_warning, the test can still
be overriden. Currently, chpass and pwd_mkdb are the only users
of pw_scan() and neither of them overrides the environment variable
test.

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.

Fix typo in xref in NOTES section.

Correct a typo :-).

Make use_yp() smarter about figuring out whether a user is local or
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.

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.)

Add a `-p' option, allowing the super-user to directly set a user's
encrypted password. Kerberized `login' might use this, if I get around
to implementing the complete Allspice System behavior.
