748554442d Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
  functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
    . getgrent, getgrnam, getgrgid
    . getpwent, getpwnam, getpwuid
    . getusershell
    . getaddrinfo
    . gethostbyname, gethostbyname2, gethostbyaddr
    . getnetbyname, getnetbyaddr
    . getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc.  rc.network has been modified
  to warn that host.conf is no longer used at boot time.  In addition, if
  there is a host.conf but no nsswitch.conf, the latter is created at boot
  time from the former.

8d21f19e4e 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.

559bbb333e Add $Id$, to make it simpler for members of the translation teams to
track.

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

4db40135ef PR: bin/3478
Have pwd_mkdb lock the source file while rebuilding the database.  When
    called by programs such as vipw, the source file is a temporary file and
    this does not conflict with the lock on /etc/master.passwd already held
    by vipw.  When run manually, however, master.passwd is typically specified
    as the argument and the locking prevents other programs from messing with
    master.passwd during the database rebuild.

    Also pwd_mkdb uses a blocking exclusive lock as it may be called from
    a script.  The -N option was added to cause pwd_mkdb to get the lock
    non-blocking and exit with an error if the attempt fails, again useful
    for scripts.

46b1a4aff5 Begin closing out PR #1519 (this requires a change to chpass too,
and both changes need to be pulled into the stable branch). The
problem here is that when pwd_mkdb creates /etc/passwd, it turns
empty UID and GID fields into zeroes. To fix this, we check the
_PWF_UID and _PWF_GID bits in the pw_fields flag: if the bits
are not set, we print an empty field instead of a zero. This way,
you don't get zeroes in the UID or GID fields unless you explicit
want them.

70bae2bee1 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.

pwd_mkdb.c:

- Don't save the PLUSCNT and MINUSCNT tokens: we don't need them anymore.

- Count the + and - entires for NIS together instead of counting + and -
  entries seperately. Index all special NIS entries using new _PW_KEYYPBYNUM
  token.

pwd.h:

- Remove the PLUSBYNUM, MINUSBYNUM, PLUSCNT and MINUSCNT tokens and replace
  then with a single _PW_KEYYPBYNUM token.

a37e0133a6 Re-enable +::::::::: wildcards that I had previously disallowed.
Note: if you put +::0:0:::::: in /etc/master.passwd as your only NIS
entry, it will cause all NIS uids and gids to be remapped to zero. This
is *intentional*. That's the way it's supposed to work. Enabling NIS with
no remapping at all is done with +:::::::::, not +::0:0::::::. Similarly,
+:::::::::/bin/csh will remap the shells of all NIS users to /bin/csh.
Or, you could do +wpaul:::::::::/bin/csh to remap NIS user wpaul's shell
to /bin/csh but leave everyone else alone.

a8b9de3061 - Add support for embedding special entries in the password databases

from having to do all the work.

- Fix potential bug: when pwd_mkdb writes the YP-enabled flag to the secure
password database, it uses the wrong database descriptor. (It uses the
descriptor from the non-secure database, which is already closed by the time
things are being written into the secure dastabase).
