You can unlock the lockbox internally by running the unlockLockbox script.
For Linux, [Product directory]/tools/passphrase/unlockLockbox.sh
This can be run by any user. It prompts for the security answers. If the answer to any one question is correct, it internally unlocks the lockbox. It does not provide the lockbox passphrase to the user. If the answer is incorrect, then the user has to contact the system administrator who can use the “Decrypting functionality” to get the lockbox passphrase.
