* NEWS, libmisc/chowntty.c, libmisc/utmp.c: is_my_tty() moved from
utmp.c to chowntty.c. checkutmp() now only uses an existing utmp
entry if the pid matches and ut_line matches with the current tty.
This fixes a possible DOS when entries can be forged in the utmp
file.
* libmisc/chowntty.c, src/login.c, lib/prototypes.h: Remove the
tty argument from chown_tty. chown_tty always changes stdin and
does not need this argument anymore.
* src/login.c, man/login.1.xml: the username is not an optional
parameter of -f. Fix the getopt optstring, remove the parsing of
username in the -f processing block, and remove unnecessary checks
(username cannot be parsed twice anymore), better documentation of
the synopsis.
* src/login.c: Use failent_user to log to audit. username is the
caller, not the user login tries to authenticate.
* src/login.c: Use pwd->pw_name instead of pwd->pw_uid. This might
be more precise (name must be unique, uid might not be).
* man/passwd.1.xml: passwd cannot change the full name of the
user, the user's login shell; but it can change the account or
password validity period. Thanks to Reuben Thomas.
* src/useradd.c: Added missing declaration of Mflg.
* src/pwck.c: Only unlock files if they were locked before (e.g.
not in read-only mode).
* src/pwck.c: Quote the username in error messages (harmonization
with other messages).
* libmisc/find_new_gid.c: Fixed typo (s/grp->gr_gid/group_id/).
* libmisc/find_new_gid.c: Likewise.
* libmisc/setugid.c, src/login_nopam.c, src/suauth.c,
lib/getdef.c: Replace the %m format string by strerror(). This
avoids errno to be reset between the system call error and the
report function.
* NEWS, etc/login.defs: New CREATE_HOME variable to tell useradd
to create a home directory for new users.
* src/useradd.c, man/useradd.8.xml: New -M/--no-create-home option
and CREATE_HOME usage. System accounts are not impacted by
CREATE_HOME.
* man/useradd.8.xml: Indicate that a new group is created by
default.
* src/useradd.c: Removed TODO item (moved to the TODO file).
* man/login.defs.d/USERGROUPS_ENAB.xml: Fix typo: new <para> tag
before the previous one is closed. This caused a missng
explanation for USERGROUPS_ENAB.
* man/groupadd.8.xml: Remove the list of (short) options from the
SYNOPSIS. Replaced with [options] for consistency with other tools
and maintainability.
From RedHat's patch shadow-4.1.2-sysAccountDownhill.patch
Thanks to Peter Vrabec.
* NEWS, libmisc/find_new_gid.c, libmisc/find_new_uid.c: Build an
index of used IDs to avoid a database request for each id in the
allowed range (when the highest allowed ID is already used).
This speedups the addition of users or groups when the highest
allowed ID is already used. The additional memory usage of the
tools should be acceptable when UID_MAX/SYS_UID_MAX are set to a
reasonable number.

src/chsh.c: If the username cannot be determined, report it as
such (not a PAM authentication failure).
* NEWS: Added configure --enable-account-tools-setuid (default) /
--disable-account-tools-setuid options. This permits to disable
the PAM authentication of the caller for chage, chgpasswd,
chpasswd, groupadd, groupdel, groupmod, newusers, useradd,
userdel, and usermod. This authentication is not necessary when
these tools are not installed setuid root.
* configure.in: Added option --enable-account-tools-setuid to
enable/disable the usage of PAM to authenticate the callers of
account management tools: chage, chgpasswd, chpasswd, groupadd,
groupdel, groupmod, useradd, userdel, usermod.
