Logging passwords of SSH attacks

["Dotan Cohen" <dotancohen@gmail.com>]

I get a few thousands of these every day in the logs:
Illegal users from:
    70.85.222.106 (sales.gbdweb.com): 518 times
       anna/password: 1 time
       apache/password: 1 time
       arthur/password: 1 time
       attack/password: 1 time
       awharton/password: 1 time

How can I start logging the passwords attempted as well as the
usernames? Thanks.
