+## Introduction
+The shadow-utils package includes the necessary programs for
+converting UNIX password files to the shadow password format, plus
+programs for managing user and group accounts. The pwconv command
+converts passwords to the shadow password format. The pwunconv command
+unconverts shadow passwords and generates a passwd file (a standard
+UNIX password file). The pwck command checks the integrity of password
+and shadow files. The lastlog command prints out the last login times
+for all users. The useradd, userdel, and usermod commands are used for
+managing user accounts. The groupadd, groupdel, and groupmod commands
+are used for managing group accounts.

@@ -2,9 +2,6 @@ People keep sending various adduser programs and scripts...  They are
 all in this directory.  I haven't tested them, use at your own risk.
 Anyway, the best one I've seen so far is adduser-3.x from Debian.
 
-atudel is a perl script to remove at jobs owned by the specified user
-(atrm in at-2.9 for Linux can't do that).
-
 udbachk.tgz is a passwd/group/shadow file integrity checker.

-** 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 thier 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???)

-X.TH GROUPMEMS 8
-X.SH NAME
-groupmems \- Administer members of a user's primary group
-X.SH SYNOPSIS
-X.B groupmems
-\fB-a\fI user_name \fR |
-\fB-d\fI user_name \fR |
-\fB-l\fR |
-\fB-D\fR |
-[\fB-g\fI group_name \fR]
-X.SH DESCRIPTION
-The \fBgroupmems\fR utility allows a user to administer their own
-group membership list without the requirement of superuser privileges.
-The \fBgroupmems\fR utility is for systems that configure its users to
-be in their own name sake primary group (i.e., guest / guest).
-X.P
-Only the superuser, as administrator, can use \fBgroupmems\fR to alter
-the memberships of other groups.
-X.IP "\fB-a \fIuser_name\fR"
-Add a new user to the group membership list.
-X.IP "\fB-d \fIuser_name\fR"
-Delete a user from the group membership list.
-X.IP "\fB-l\fR"
-List the group membership list.
-X.IP "\fB-D\fR"
-Delete all users from the group membership list.
-X.IP "\fB-g \fIgroup_name\fR"
-The superuser can specify which group membership list to modify.
-X.SH SETUP
-The \fBgroupmems\fR executable should be in mode \fB2770\fR as user \fBroot\fR
-and in group \fBgroups\fR.   The system administrator can add users to
-group groups to allow or disallow them using the  \fBgroupmems\fR utility
-to manager their own group membership list.
-X.P

- * pwdauth.c - program to verify a given username/password pair.
- *
- * Run it with username in argv[1] (may be omitted - default is the
- * current user), and send it the password over a pipe on stdin.
- * Exit status: 0 - correct password, 1 - wrong password, >1 - other
- * errors.  For use with shadow passwords, this program should be
- * installed setuid root.
- *
- * This can be used, for example, by xlock - you don't have to install
- * this large and complex (== possibly insecure) program setuid root,
- * just modify it to run this simple program to do the authentication.
- *
- * Recent versions (xlockmore-3.9) are cleaner, and drop privileges as
- * soon as possible after getting the user's encrypted password.
- * Using this program probably doesn't make it more secure, and has one
- * disadvantage: since we don't get the encrypted user's password at
- * startup (but at the time the user is authenticated), it is not clear
- * how we should handle errors (like getpwnam() returning NULL).
- * - fail the authentication?  Problem: no way to unlock (other than kill
- *   the process from somewhere else) if the NIS server stops responding.
- * - succeed and unlock?  Problem: it's too easy to unlock by unplugging
- *   the box from the network and waiting until NIS times out...

-Hello Marek,
-
-I have created a diffile against the 980403 release that adds
-functionality to newusers for automatic handling of users with only
-anonymous ftp login (using the guestgroup feature in ftpaccess, which
-means that the users home directory looks like '/home/user/./'). It also
-adds a commandline argument to specify an initial directory structure
-for such users, with a tarball normally containing the bin,lib,etc
-directories used in the chrooted environment.
-
-I am using it to automatically create chunks of users with only ftp
-access for a webserver.
-
-I have tried to follow your coding standards and I believe it is bug
-free but.. well, who knows. :) It's not much code however.
-
-I hope you find it useful. Do what you like with it, feel free to ask if
-anything is unclear.
-
-Best rgds,

+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'

+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
