Disable single user

[John McCoy, Jr.]

I want to disable our "guest" account that allows anonymous printing from
using webmail.
Running IMP 2.2.4 with mySQL Database for preferences and contacts.
Guest has a null password and a bad shell so it can't be logged into.
Yes the long-term plan is to get rid of this account!!!
