MAPDAV - More Accurate Password Dictionary Attack Vector

MAPDAV, or the More Accurate Password Dictionary Attack Vector, is designed to use what is known about a user or users (ex, username, first name, middle name, last name, etc) on a unix/linux system from a /etc/passwd file and tries to come up with probable combinations that could be the user's password. An administrator could run the output through a cracker and see if their user's passwords are anything easy to guess.
