Account flags

There are three different flags that can be set to alter password behavior:

• Only root can change password
  If this flag is set then only the root user can change password information.

• User must choose new password
  If this flag is set then the user is forced to change their password the next time a login command or an su command is given for the user.

• Don't check password restrictions
  If this flag is set then new passwords choosen need not follow the password guidelines.
