+** 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!
+
+** -- Chris, chris@ferret.lmh.ox.ac.uk
+
+** 03/17/96
+** hacked a bit more, removed unused code, cleaned up for gcc -Wall.

+** 02/26/96
+** modified to call shadow utils (useradd,chage,passwd) on shadowed 
+** systems - Cristian Gafton, gafton@sorosis.ro

+** 6/27/95
+** shadow-adduser 1.4:
+**
+** now it copies the /etc/skel dir into the person's dir,

+** shadow-adduser 1.3:
+** 
+** Basically a bug-fix on my additions in 1.2.  Thanks to Terry Stewart 
+** (stew@texas.net) for pointing out one of the many idiotic bugs I introduced.
+** It was such a stupid bug that I would have never seen it myself.

+** 
+** 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???)

+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?)

++.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
