About the Password Strength module

The Password Strength module reports the users that can log in without a password, and passwords that do not conform to specified format, length, expiration, and history requirements. It also applies dictionary tests to detect passwords that are easily guessed.

The module checks local NIS and/or /etc/passwd files on standard UNIX computers and /tcb files and shadow password files on enhanced or trusted UNIX computers.

Red Hat Linux operating systems must be configured for both of the following:

The pam_cracklib.so module and standard UNIX password encryption
The pam_pwdb.so module and the shadow password file
