The name of a program that can be used to check password complexity. The password is sent to the program's standrad input. The program must return 0 on good password any other value otherwise. In case the password is considered weak (the program do not return 0) the user will be notified and the password change will fail. Note: In the example directory there is a sample program called crackcheck that uses cracklib to checkpassword quality. Disabled check password script = /usr/local/sbin/crackcheck
