-** 04/21/96
-** hacked even more, replaced gets() with something slightly harder to buffer
-** overflow. Added support for setting a default quota on new account, with
-** edquota -p. Other cleanups for security, I let some users run adduser suid
-** root to add new accounts. (overflow checks, clobber environment, valid 
-** shell checks, restrictions on gid + home dir settings).
-
-** Added max. username length. Used syslog() a bit for important events. 
-** Support to immediately expire account with passwd -e.
-
-** Called it version 2.0! Because I felt like it!

-** shadow-adduser 1.2:
-** I took the C source from adduser-shadow (credits are below) and made
-** it a little more worthwhile.  Many small changes... Here's
-** the ones I can remember:
-** 
-** Removed support for non-shadowed systems (if you don't have shadow,
-**     use the original adduser, don't get this shadow version!)
-** Added support for the correct /etc/shadow fields (Min days before
-**     password change, max days before password change, Warning days,
-**     and how many days from expiry date does the account go invalid)
-**     The previous version just left all of those fields blank.
-**     There is still one field left (expiry date for the account, period)
-**     which I have left blank because I do not use it and didn't want to
-**     spend any more time on this.  I'm sure someone will put it in and
-**     tack another plethora of credits on here. :)
-** Added in the password date field, which should always reflect the last
-**     date the password was changed, for expiry purposes.  "passwd" always
-**     updates this field, so the adduser program should set it up right
-**     initially (or a user could keep their initial password forever ;)
-**     The number is in days since Jan 1st, 1970.
-**
-**                       Have fun with it, and someone please make
-**                       a real version(this is still just a hack)
-**                       for us all to use (and Email it to me???)

-** adduser 1.0: add a new user account (For systems not using shadow)

-** FURTHER modifications to enable shadow passwd support (kludged, but
-** no more so than the original)  by Dan Crowson - dcrowson@mo.net
-**
-** Search on DAN for all changes...
-**
-*****
-**
-** cc -O -o adduser adduser.c
-** Use gcc if you have it... (political reasons beyond my control) (chris)
-**
-** I've gotten this program to work with success under Linux (without
-** shadow) and SunOS 4.1.3. I would assume it should work pretty well
-** on any system that uses no shadow. (chris)
-**
-** If you have no crypt() then try
-** cc -DNO_CRYPT -O -o adduser adduser.c xfdes.c
-** I'm not sure how login operates with no crypt()... I guess
-** the same way we're doing it here.

-Read this file first for a brief overview of the new versions of login
-and passwd.
-
-
---Shadow passwords
-
-The command `shadowconfig on' will turn on shadow password support.
-`shadowconfig off' will turn it back off.  If you turn on shadow
-password support, you'll gain the ability to set password ages and
-expirations with chage(1).
-
-NOTE: If you use the nscd package, you may have problems with a
-slight delay in updating the password information. You may notice
-this during upgrades of certain packages that try to add a system
-user and then access the users information immediately afterwards.
-To avoid this, it is suggested that you stop the nscd daemon before
-upgrades, then restart it again.
-
---General configuration
-
-Most of the configuration for the shadow utilities is in
-/etc/login.defs.  See login.defs(5).  The defaults are quite
-reasonable.
-
-Also see the /etc/pam.d/* files for each program to configure the PAM
-support. PAM documentation is available in several formats in the
-libpam-doc package.
-
-
---MD5 Encryption
-
-This is enabled now using the /etc/pam.d/* files. Examples are given.
-
-
---Adding users and groups
-
-Though you may add users and groups with the SysV type commands,
-useradd and groupadd, I recommend you add them with Debian adduser
-version 3+.  adduser gives you more configuration and conforms to the
-Debian UID and GID allocation.
-
-Editing user and group parameters can be done with usermod and
-groupmod.  Removing users and groups can be done with userdel and
-groupdel.
-
-
--- Group administration
-
-Local group allocation is much easier.  With gpasswd(1) you can
-designate users to administer groups.  They can then securely add or
-remove users from the group.
-
-
--- What to read next?
-
-Read the manpages, the other files in this directory, and the Shadow
-Password HOWTO (included in the doc-linux package).  A large portion
-of these files deals with getting shadow installed.  You can, of
-course, ignore those parts.
-
-Also, the libpam-doc package will go a long way to allowing you to take
-full advantage of the PAM authentication scheme.

-Things that should be done:
- * Verify the files left in debian/tmp
-   + e.g. /etc/default/adduser should be installed
- * Check the build system: rebuilding the package twoce in the same tree
-   doubles the size of the diff.gz file
-
-Other points (not related to the release of a syncronized shadow):
- * compare the source with the usages and man pages
-   + probably add a sentence to chsh/chfn's manpages about authentication
-     required for ordinary users
- * do something (a tool) for the variables in login.defs
-   In Debian, some tools are not compiled with the PAM support, so upstream
-   getdef.c won't be OK.
-   It should be nice to see in each man page the set of variables used.
-   The Debian package can now compile (export DEB_BUILD_OPTIONS='nostrip debug')
-   with the debugging informations. This may be used to extract the set of
-   variables used in Debian/for each tools.
- * verify all the patches around (I've found patches for at least RedHat,
-   OWL, LFS, Mandriva, Gentoo; are they already applied?)

-Build-Depends:
-==============
- * autoconf
- * automake1.9
-   works with 1.7 or 1.9 (at least)
- * libtool
- * gettext
-   POT, PO, GMO regenerated?
- * libpam0g-dev
-   OK
- * debhelper (>= 4.1.16)
- * po-debconf
-   OK
- * quilt
-   patch system
- * dpkg-dev (>= 1.13.5)
- * xsltproc
-   used to generate the manpages
- * docbook-xsl
-   needed for /usr/share/xml/docbook/stylesheet/nwalsh/manpages/docbook.xsl
- * docbook-xml
-   manpages/docbook.xsl includes html/docbook.xsl
-   (But it is not strictly needed. The generated manpages are identical.
-   Without it, a warning is generated.)
-   Needed by JH_CHECK_XML_CATALOG([-//OASIS//DTD DocBook XML V4.1.2//EN], [DocBook XML DTD V4.1.2], [], enable_man=no)
- * libxml2-utils
-   needed by the JH_CHECK_XML_CATALOG macros
- * cdbs
-   used in debian/rules
- * libselinux1-dev [!hurd-i386 !kfreebsd-i386 !kfreebsd-amd64]
- * gnome-doc-utils (>= 0.4.3-1)
-   xml2po, 0.4.3-1 needed for the -l switch.
-
-passwd Depends:
-===============
- * ${shlibs:Depends}
-   OK
- * ${loginpam}
-   - hurd
-     login
-     libpam-modules (>= 0.72-5)
-   - other archs
-     + login (>= 970502-1)
-       login is needed because some passwd utils need /etc/login.defs
-       login is Essential, so this is just to enforce the version
-     + libpam-modules (>= 0.72-5)
- * debianutils (>= 2.15.2)
-   After 1:4.0.12-6, {add,remove}-shell are distributed in debianutils (2.15)
-   /etc/shell was forgotten and introduced in debianutils in 2.15.2
-
-passwd Conflicts:
-=================

-passwd Replaces:
-================
-   Some of the passwd man pages are also distributed in some manpages* packages.
-   Look at the debian/02/run test to optimize these dependencies.
-   NOTE: Not all maintainers have been notified.
- * manpages-de (<< 0.4-9), manpages-fi (<< 0.2-4), manpages-fr (<<1.64.0-1), manpages-hu (<< 20010119-5), manpages-it (<< 0.3.4-3), manpages-ja (<< 0.5.0.0.20050915-1), manpages-ko (<< 20050219-2), manpages-es (<< 1.55-4), manpages-es-extra (<< 0.8a-15), manpages-ru (<< 0.98-3)
-   All those packages have been updated during sarge->etch. So these Replaces
-   should be removed after lenny release
- * manpages-tr, manpages-zh
-   Those packages are still in etch, so the Replaces should be kept even
-   after lenny release

-login Pre-Depends:
-==================
- * ${shlibs:Depends}
- * libpam-runtime (>= 0.76-14)
-   sarge contained 0.76-22
-
-Why Pre-Depends? (because it's an essential package?)

-+.SH SYNOPSIS
-+\fBshadowconfig\fP \fIon\fP | \fIoff\fP
-+.SH DESCRIPTION
-+.PP
-+\fBshadowconfig on\fP active les mots de passe cachés («\ shadow passwords\ »)\ ; \fBshadowconfig off\fP les désactive. \fBShadowconfig\fP affiche un message
-+d'erreur et quitte avec une valeur de retour non nulle s'il rencontre
-+quelque chose d'inattendu. Dans ce cas, vous devrez corriger l'erreur avant
-+de recommencer.
-+
-+Activer les mots de passe cachés lorsqu'ils sont déjà activés, ou les
-+désactiver lorsqu'ils ne sont pas actifs est sans effet.
-+
-+Lisez \fI/usr/share/doc/passwd/README.Debian\fP pour une brève introduction aux
-+mots de passe cachés et à leurs fonctionnalités.
-+
-+Notez que désactiver puis réactiver les mots de passe cachés aura pour
-+conséquence la perte des informations d'âge sur les mots de passe.

-Subject: Relax usernames/groupnames checking
-
-Allows any non-empty user/grounames that don't contain ':', ',' or '\n'
-characters and don't start with '-', '+', or '~'. This patch is more
-restrictive than original Karl's version. closes: #264879
-Also closes: #377844
-
-Comments from Karl Ramm (shadow 1:4.0.3-9, 20 Aug 2003 02:06:50 -0400):
-
-I can't come up with a good justification as to why characters other
-than ':'s and '\0's should be disallowed in group and usernames (other
-than '-' as the leading character).  Thus, the maintenance tools don't
-anymore.  closes: #79682, #166798, #171179
-
-Status wrt upstream: Debian specific. Not to be used upstream
