* src/groupmems.c: Added Prog global variable to indicate the name
of the program in error messages.

* NEWS, src/groupmems.c: Check if the user added to group actually
exist. RedHat bug #455603
* NEWS, src/groupmems.c: Check if the group exists in the group
local database (/etc/group). RedHat bug #456088
effects. This avoid checking if the user exists in the local passwd
file if not necessary, and thus allow to add LDAP users to local
groups. (The user is already checked against the system
configuration with getpwnam()). Thanks to Dan Kopecek.
* src/newusers.c: Use a bool when possible instead of int
integers.
* src/newusers.c: Avoid implicit conversion of pointers / integers
/ chars to booleans.
* src/newusers.c: Ignore the return value of pam_end() before
exiting.
* src/newusers.c: Ignore return value of setlocale(),
bindtextdomain(), and textdomain().
* src/newusers.c: Avoid multi-statements lines.
* src/newusers.c: Add brackets and parenthesis.
- generation of SHA encrypted passwords (chpasswd, gpasswd, newusers,
chgpasswd; and also passwd if configured without PAM support).
The number of rounds and number of salt bytes was fixed to their lower
allowed values (resp. configurable and 8), hence voiding some of the
advantages of this encryption method. Dictionary attacks with
precomputed tables were easier than expected, but still harder than with
the MD5 (or DES) methods.
* NEWS, libmisc/salt.c (SHA_salt_size): Seed the RNG, and fix a
overflow. These caused the SHA salt size to always be 8 bytes,
instead of being in the 8-16 range. Thanks to Peter Vrabec
pvrabec@redhat.com for noticing.
* NEWS, libmisc/salt.c (SHA_salt_rounds): Seed the RNG with
seedRNG instead of srand, and fix the same overflow. This caused
the number of rounds to always be the smallest one.
SIGSTOP handling. Raise the signal which stopped the child instead
of always SIGSTOP.
Import Debian patch 406_vipw_resume_properly.
Thanks to Dean Gaudet.
* NEWS, src/vipw.c: Resume properly after ^Z.
Fail if the feature is requested but the library (or
header file) could not be found. If nothing is specified, enable
the feature only if we can find the library (or header file).
$(pamd_files). Remove the duplicate useradd. And sort
alphabetically. Thanks to Mark Rosenstand <mark@borkware.net>.
* NEWS: Prepare next release, 4.1.2.
files are unlocked on exit. Unlock locked files in fail_exit().
Prefer fail_exit() over exit().
* NEWS, src/groupmod.c: When the GID of a group is changed, update
also the GID of the passwd entries of the users whose primary
group is the group being modified.
removed is used by different entries (like commonio_update does).
* NEWS: This fix the behavior of groupdel when the system is not
configured to support split group but different group entries
have the name of the group to be deleted.
unlocked on exit. Add function fail_exit(). Use fail_exit()
instead of exit().
* src/groupdel.c: Fail immediately instead of increasing errors.
Better handling of error cases, like locked group or gshadow file.
to Christian Henz (http://bugs.debian.org/467488)
* src/gpasswd.c (get_group): Do not fail if gshadow is not present. Just use
the group file and set the grent structure
* src/gpasswd.c (check_perms): The permissions should be checked
using both the gshadow and group file. Add a <struct group *>
parameter, and check if the gshadow file exists (is_shadowgrp).
* src/gpasswd.c (main): Do not use sgent.sg_mem or sgent.sg_adm if
the gshadow file is not present (sgent is not initialized in that
case). The fields of sgent can be set, but not used.
* src/newusers.c: The user's ID must be found before the group ID
to mimic useradd's behavior choices of UID and GID.
* src/newusers.c: Reuse the generic find_new_uid() and
find_new_gid() functions. This permits to respect the
UID_MIN/UID_MAX and GID_MIN/GID_MAX variables, should
* src/newusers.c: Check if the user or group exist using the
external databases (with the libc getpwnam/getgrnam functions).
Refuse to update an user which exist in an external database but
does not exist in the local database.
* src/newusers.c: Check the usernames and groupnames with
check_user_name() and check_group_name()
* src/newusers.c: Use isdigit() for readability.
* src/newusers.c: Check if numerical IDs are valid (no remaining
chars).
* NEWS, src/newusers.c: Fix the support for the NONE crypt method.
* src/newusers.c: Fix shadow group support (the list of admins was
not defined; it is now set to an empty list).
microseconds to avoid having the same salt for different passwords
generated in the same second. This permits to avoid using the same salt
for different passwords in newusers.
differ from the old ones. If a requested new value is equal to the old
one, no changes will be performed for that field. If no fields are
changed, usermod will exist successfully with a warning. This avoids
logging changes to syslog when there are actually no changes.
unknown GID (either the user was deleted during the user's newgrp
session or the user's passwd entry referenced an invalid group).
Add a syslog warning in that case.
* src/newgrp.c: Add an end of line when reporting an invalid
password.
(it required an argument, but should behave as -D)
* NEWS, man/useradd.8.xml: Document the --defaults option, which
was already described in the useradd's Usage information.
changes, except for the following bug fix: no syslog logging if a passwd
or group file was specified on the command line without a shadowed
database file, even if the system shadowed database was changed).
