And for CHAP, you can log CHAP-Challenge and CHAP-Response. Those values are
sufficient to be able to tell afterwards whether the user used a given
password or not. (i.e. you can test "did they use password '123456'"?)
You can also make a dictionary attack to try to determine what password they
used, which will often succeed if it's a simple password.
