I need to configure an Ubuntu server to follow a strict company password policy that specifies the following:
- at least one upper case
- at least one lower case
- at least one digit
- at least one special character
I've had a look around and all I have found is the instructions for specifying the password length; but, I have yet to find something that relates to specifying the content of the password regarding the above points.
Any help would be appreciated.
