### passwordage
The `passwordage` matcher tests the number of days a user changed its password:
its('passwordage') { should_be <= 365 }
where `365` represents the number of days since the last password change.
### maxbadpasswords
The `maxbadpasswords` matcher tests the count of max badpassword settings for a specific user.
its('maxbadpasswords') { should eq 7 }
where `7` is the count of maximum bad password attempts.
### badpasswordattempts
The `badpasswordattempts` matcher tests the count of bad password attempts for a user.
its('badpasswordattempts') { should eq 0 }
where `0` is the count of bad passwords for a user.
On Linux based operating systems it relies on `lastb` and for Windows it uses information stored for the user object.
These settings will be resetted to `0` depending on your operating system configuration.
