NAME
pam_passwdqc
- Password quality-control PAM module
SYNOPSIS
[
service-name
]
module-type
control-flag
pam_passwdqc
[
options
]
DESCRIPTION
The
module is a simple password strength checking module for
PAM.
In addition to checking regular passwords, it offers support for
passphrases and can provide randomly generated ones.
The
module provides functionality for only one PAM management group:
password changing.
In terms of the
module-type
parameter, this is the
``password
''
feature.
The
Fn pam_chauthtok
service function may ask the user for a new password, and verify that
it meets certain minimum standards.
If the chosen password is unsatisfactory, the service function returns
PAM_AUTHTOK_ERR
The set of options that may be passed to the module is exactly the
same as the set of options that may be specified in the configuration
file (suggested location
/etc/passwdqc.conf
to be specified in the
config=/etc/passwdqc.conf
option). These options are described in
passwdqc.conf5.

AUTHORS
The
module was written for Openwall GNU/*/Linux by
An Solar Designer Aq solar at openwall.com .
This manual page was written for the
Fx Project by
ThinkSec AS and NAI Labs, the Security Research Division of Network
Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035
(``CBOSS''
)
as part of the DARPA CHATS research program.
It has since been revised, most importantly to refer to
passwdqc.conf5
instead of describing the options right on this page.
