Forgotten Password Recovery
If the administrator of a system forgets the password of the user admin, the following method can be
used to reset the password to the empty password so that the system can be accessed as admin with
no password required. The password can then reset to a secure one via the CLI.
The procedure is:
1. Boot the system to single user and execute a script to reset the admin password in the active
database. If any database corruption is suspected, the script resets the system database to its
initialized default. The admin password is not set in such a database. A system booted to single
user mode does not require a privileged user password. The system can be rebooted by power
cycling. It is assumed the person using this procedure is able to access the system’s console and
can see the entire boot process (this is either over a serial console or the system’s direct console).
2. Once the system is starting to boot, the following GRUB message should be seen (GRUB is the
boot loader for the system):
Grub Loading stage 2...
Press any key to continue.
[This message repeats (once a second) on a new line several times, and if no key is pressed the
system will boot as normal. You should press a key to enter the GRUB command line]
.
.
.
Press any key to continue.
[Assume the user presses the space key (for example)]
3. Next, you should see the following GRUB text which allows you to select one of the 2 images to be
booted. Choose the desired image by using the arrow keys so that GRUB indicates that the
desired entry will be booted.
GRUB version 0.93 (640K lower / 259536K upper memory)

Use the ^ and v keys to select which entry is highlighted.
Press enter to boot the selected OS, 'e' to edit the
commands before booting, 'a' to modify the kernel arguments
before booting, or 'c' for a command-line.
Highlighted entry is 1:
If a selection is not made within a few seconds, the system will automatically boot the image that
is highlighted. You should press the ekey to enter the edit command mode. This will give you the
ability to change command options that are part of the boot process. Specifically, you will add the
option single to force the system into single user mode.
When the ekey is pressed, the GRUB text shown below will be seen. (Note the 0and 1entries now
refer to the selected image that is booting). You should now edit the kernel line. This is done
using the arrow keys on your keyboard to select the 1: line — press the down arrow key one time.
The message at the bottom should now indicate Highlighted entry is 1:
