What if you left the entry in /etc/passwd but in addition to setting the 
password field to !! (or some other invalid hash), you changed their home 
directory as well? (Perhaps to /home/user-locked or something similar.) 
Then ssh-keys won't be able to access any private keys in their ~/.ssh/ 
directory (because ~/ will now be a non-existent directory).

Does that work to completely lock someone out?
