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.
