    If the machines are internal to your network then DoS attacks should not
    be a major factor in this. The best way to do this is to use PAM
    modules and customize it for your environment. This may not be the
    simplist method but it will get you where you want to go. Take a look
    at the /etc/default/passwd options as well. They wont let you disable
    an account this way but will allow you to force other options.
