+.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

-Subject: Revert "lib/, src/: Use local time for human-readable dates"
-
-This reverts commit 3f5b4b56268269fefed55aa106f382037297d663.
-
-The dates are stored as UTC, and are stored as a number of days since
-Epoch.  We don't have enough precision to translate it into local time.
-Using local time has caused endless issues in users.
-
-This patch is not enough for fixing this issue completely, since
-printing a date without time-zone information means that the date is a
-local date, but what we're printing is a UTC date.  A future patch
-should add time-zone information to the date.
-
-For now, let's revert this change that has caused so many issues.
-
-Fixes: 3f5b4b562682 (2024-08-01; "lib/, src/: Use local time for human-readable dates")

-Subject: lib/getdate.y: Ignore time-zone information and use UTC
-
-There is exactly one caller of this function, and it wants a date, not a
-time.  It is useless to be able to parse local dates, because we
-ultimately store a UTC date.  To avoid confusion, unconditionally use
-UTC.  Since this code had important bugs regarding offset, we can safely
-assume that no existing users rely on being able to use their local
-date (this never worked correctly).
-
-Also, the code parsing time zones was quite bad.

-Subject: src/chfn.c: Partially revert "lib/,
- src/: Use strsep(3) instead of its pattern"
-
-This partially reverts commit 16cb664865541162c504a6f5ef5ca4b38b5e0c9a.
-
-I'll try to reintroduce this change more carefully.
-For now, let's revert to a known-good state.
-
-The problem was due to accidentally ignoring the effects of the 'break'
-on the 'cp' variable.
-
-Fixes: 16cb66486554 (2024-07-01; "lib/, src/: Use strsep(3) instead of its pattern")
