To disable a user account, edit, as root, the
'' file (assuming
you're using shadow passwords; if not, edit the
'' file instead),
and replace the password (which is stored in its encrypted form) with a
``*'' asterisk character. All Unix passwords, regardless of length (up
to a maximum of 8 characters), are stored in the password file as
encrypted strings of 13 characters. Therefore, by replacing the password
with a single ``*'' character, it is impossible for the user to sign
Note: Note: This method will require you to assign a new password to the user if you re-enable the account, since the encrypted password field will have been replaced. One solution to this which seems to be popular among system administrators is to simply prefix the ``*'' asterisk character in front of the encrypted password to disable the account, and simply removing the asterisk to enable it.

'' files, see Section 6.6 below.
