Account is disabled but console login is allowed Terminal is disabled but root login is allowed
These messages are associated with
the superuser logging onto the override terminal.
Under the assumption that the console device (including a serial
console) is a special device and considered a physical resource
worth protecting, a lock on the superuser account does not
prevent the superuser from logging into the console.
This presents a means for entering the system even when all other
accounts or terminals are locked. Before continuing, use the
audit trail to investigate the reasons for the lock.
A lockout caused by unsuccessful login attempts on the system
console is cleared automatically, but lockouts due to other
reasons remain in effect.
The console, in effect, is never locked out for the superuser.
