A More Complex MPF

• Next we’ll look at a slightly more complex MPF. Given the user authenticating and the system being authenticated to, we could construct an formula like this:

• <u>!<h>.<d>

• In this formula:

• • <u> represents the first letter of the username
  • <h> represents the first letter of the hostname or first number of the first address octet
  • <d> represents the first letters of the remaining domain name parts or first numbers of the remaining address octets concatenated together.

• We also added another special character, the ‘.’ between <h> and <d>
