+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?)

+     + login (>= 970502-1)

+ * debianutils (>= 2.15.2)

++.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

++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

+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

+Subject: tests/: Support run_some from exported tarball
+
+common/config.sh currently tries to find the top directory by looking
+for .git.  There are also many places under tests/ where we use
+hard-coded ../../.. to find things like ${TOP_DIR}/lib.
+
+We don't actually ship the tests with 'make dist'.  So we will
+be exporting tests/ as a separate tarball.  In particular, I want
+to then import this in the debian package.  However, there it will
+be under shadow.git/debian/tests, not shadow.git/tests.
+
+To support this, accept the environment variable BUILD_BASE_DIR,
+which should point to shadow.git.
+
+An alternative would be to move the tests to their own git
+tree.  However, keeping tests in separate git tree tends to
+lead to repos getting out of sync.  And we'd still need to accept
+something like BUILD_BASE_DIR.
+
+Note there are a lot of tests under run-all, which I'm not converting
+as they currently are not being run in CI, so I'm more likely to
+break something.
