-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.

- * pwdauth.c - program to verify a given username/password pair.
- *
- * Run it with username in argv[1] (may be omitted - default is the

- * 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.

++.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.

-This is my wishlist for the shadow suite, in no particular order.  Feel
-free to do anything from this list and mail me the diffs :-).
-
-Patches in diff -u format, against the latest version (sometimes in the
-"beta" directory) are preferred and make my job easier.  Please, no
-MIME, base64, quoted-printable, or HTML.  For very big patches, or if
-your mailer can corrupt them, please use gzip and uuencode.  Thanks!
-
-New ideas to add to this list are welcome, too.  --marekm
-
-- fix all the bugs, of course
-- implement "su only" accounts (no logins, only su from other account)
-- rewrite getdef.c to be more general? (no hardcoded names)
-- patch for rlogind/telnetd to create utmp entry and fill in ut_addr
-- option to specify encrypted password in passwd (for yppasswdd, so it
-  doesn't need to know about shadow/non-shadow); should probably use a pipe
-  (less insecure than command line arguments)
-- add support for changing NIS passwords
-- add option to check passwords by piping them to external programs
-- add functionality of the contrib/rpasswd.c wrapper to passwd
-- option to generate pronounceable passwords (like on SCO), external program?
-- poppassd (remote password change for eudora etc.)
-- add support for passwd/shadow db files (glibc)
-- vipw: check password files for errors after editing
-- add "maximum time users allowed to stay logged in" limit option to logoutd
-- handle quotes in /etc/environment like the shell does (but sshd doesn't...)
-- better utmpx support (logoutd, ...)
-- better OPIE support (report number of logins left, etc.)
-- new option for /etc/suauth: don't load user's environment (force "su -")
-  suggested by Ulisses Alonso Camaro
-- find out why recent releases won't compile on Solaris
-- newusers should be able to copy /etc/skel to the new home directory
-  (like useradd)
-- add directories where other packages can add hooks for package-specific
-  per-user configuration, to be executed with run-parts. Some hooks should
-  be executed at package install time for existing users, likewise for
-  package removal and possibly modification.  (Debian Bug#36019)

+ * SYNOPSIS
+ *	[[gnu::malloc(erase_pass)]]
+ *	char *agetpass(const char *prompt);
+ *	char *agetpass_stdin();
+ *
+ *	void erase_pass(char *pass);
+ *
+ * ARGUMENTS
+ *   agetpass()
+ *	prompt	String to be printed before reading a password.
+ *
+ *   erase_pass()
+ *	pass	password previously returned by agetpass().
+ *
+ * DESCRIPTION
+ *   agetpass()
+ *	This function is very similar to getpass(3).  It has several
+ *	advantages compared to getpass(3):
+ *
+ *	- Instead of using a static buffer, agetpass() allocates memory
+ *	  through malloc(3).  This makes the function thread-safe, and
+ *	  also reduces the visibility of the buffer.
+ *
+ *	- agetpass() doesn't reallocate internally.  Some
+ *	  implementations of getpass(3), such as glibc, do that, as a
+ *	  consequence of calling getline(3).  That's a bug in glibc,
+ *	  which allows leaking prefixes of passwords in freed memory.
+ *
+ *	- agetpass() doesn't overrun the output buffer.  If the input
+ *	  password is too long, it simply fails.  Some implementations
+ *	  of getpass(3), share the same bug that gets(3) has.
+ *
+ *	As soon as possible, the password obtained from agetpass() be
+ *	erased by calling erase_pass(), to avoid possibly leaking the
+ *	password.
+ *
+ *   agetpass_stdin()
+ *	This function is the same as previous one (agetpass). Just the
+ *	password is read from stdin and terminal is not required.
+ *
+ *   erase_pass()
+ *	This function first clears the password, by calling
+ *	explicit_bzero(3) (or an equivalent call), and then frees the
+ *	allocated memory by calling free(3).
+ *
+ *	NULL is a valid input pointer, and in such a case, this call is
+ *	a no-op.
+ *
+ * RETURN VALUE
+ *	agetpass() returns a newly allocated buffer containing the
+ *	password on success.  On error, errno is set to indicate the
+ *	error, and NULL is returned.
+ *
+ * ERRORS
+ *   agetpass()
+ *	This function may fail for any errors that malloc(3) or
+ *	readpassphrase(3) may fail, and in addition it may fail for the
+ *	following errors:
+ *
+ *	ENOBUFS
+ *		The input password was longer than PASS_MAX.
+ *
+ * CAVEATS
+ *	If a password is passed twice to erase_pass(), the behavior is
+ *	undefined.
