The pam_pwcheck is a PAM module for password strength checking. It makes additional checks upon password changes, but it doesn't make the change itself. It only provides functionality for one PAM management group: password changing. This module works in the following manner: if enabled it calls at first the Cracklib routine to check the strength of the password; if crack likes the password, the module does an additional set of strength checks. This PAM module reads /etc/login.defs. Please read the manual page for this configuration file for more information. Version 2.1 removes some wrong runtime error messages and allows again more than 8 characters for blowfish passwords. Version 2.0 of pam_pwcheck makes it again possible, that root can change the NIS password of another user. Support for PAM_INCOMPLETE and the "nopasswordverify" option. Version 1.7 of pam_pwcheck implements the "remember" option. The last old passwords from an user will be saved and the new password will be checked against the old ones. The user is not allowed to reuse one of the last passwords. The number of remembered passwords is configurable. Version 1.5 of pam_pwcheck allows the use of a global config file (/etc/security/pam_pwcheck.conf). |
