We are real strict when it comes to passwords. Every 60 days the admins have to change passwords on all of the accounts. And there is pretty strict enforcement of the type of passwords chosen. This is a tedious and monotonous job. Ww don't use NIS or LDAP, so this has to be done on each machine. ... (5 Replies)

PAM_PWHISTORY(8) Linux-PAM Manual PAM_PWHISTORY(8)
NAME
pam_pwhistory - PAM module to remember last passwords
SYNOPSIS
pam_pwhistory.so [debug] [use_authtok] [enforce_for_root] [remember=N] [retry=N] [authtok_type=STRING]
DESCRIPTION
This module saves the last passwords for each user in order to force password change history and keep the user from alternating between the
same password too frequently.
This module does not work together with kerberos. In general, it does not make much sense to use this module in conjunction with NIS or
LDAP, since the old passwords are stored on the local machine and are not available on another machine for password history checking.
OPTIONS
debug
Turns on debugging via syslog(3).
use_authtok
When password changing enforce the module to use the new password provided by a previously stacked password module (this is used in the
example of the stacking of the pam_cracklib module documented below).
enforce_for_root
If this option is set, the check is enforced for root, too.
remember=N
The last N passwords for each user are saved in /etc/security/opasswd. The default is 10. Value of 0 makes the module to keep the
existing contents of the opasswd file unchanged.
retry=N
Prompt user at most N times before returning with error. The default is 1.
authtok_type=STRING
See pam_get_authtok(3) for more details.
MODULE TYPES PROVIDED
Only the password module type is provided.
RETURN VALUES
PAM_AUTHTOK_ERR
No new password was entered, the user aborted password change or new password couldn't be set.
PAM_IGNORE
Password history was disabled.
PAM_MAXTRIES
Password was rejected too often.
PAM_USER_UNKNOWN
User is not known to system.
EXAMPLES
An example password section would be:
#%PAM-1.0
password required pam_pwhistory.so
password required pam_unix.so use_authtok
In combination with pam_cracklib:
#%PAM-1.0
password required pam_cracklib.so retry=3
password required pam_pwhistory.so use_authtok
password required pam_unix.so use_authtok
FILES
/etc/security/opasswd
File with password history
