Recovery Procedures

CORE Password Reset

The following recovery procedures apply to users that are authenticated by CORE:

• Password change. A user may change its password using the ucl user change-pwd command.
• Password reset. To reset the other user's password, you must be an SOSecurity officer - UKC partition administrator role. or Admin of EP. Refer to the following table:

To reset the password of ...	Required Role	Command
SOSecurity officer - UKC partition administrator role. of the Root partition	System Admin on EP	ekm_recover_root_so_pwd
SOSecurity officer - UKC partition administrator role. of any partition	Root SOSecurity officer - UKC partition administrator role.	ucl user recover-pwd
Any member in a partition	The partition's SOSecurity officer - UKC partition administrator role.	ucl user reset-pwd

Partition Lockout Release

Use the following procedures to recover from unlikely partition lockout situations.

Lockout Case	Impact	Recovery	Note
None of the partition certificates can be used to access the partition.	All key material in the partition is out of reach for the CORE clients.	Create a new certified client.	1
The number of active SOs in a partition is below its quorum requirements.	All actions that require quorum approval are blocked.	Adjust the quorum requirements.	2

Notes:

1. Recovery of Partition's Certificate.
2. Partition Quorum Reset

Recovery of Partition's Certificate

This case addresses an unlikely event when all certificates of a partition owned by its clients are lost or useless (e.g. expired, signed by expired CA, etc..). To recreate the first certificate of a partition:

• A standard partition. Root SO must use the ucl partition recover command.

  This command:

  • Clears the partition's client list in the CORE database. (These clients are useless without certificates).
  • Creates a new client and saves its certificate (<partition-name>.pfx) in the local CORE Client Certificates Folder.
  • The client name is the hostname of an appliance that executed the command.

• The Root partition. EP Admin must use the ekm_recover_root_partition script.

  This script is functionally similar to the previous command, except that it must be executed by the EP Admin. In particular, it:

  • Clears the Root partition's client list in the CORE database.
  • Creates a new Root client and saves its certificate (root.pfx) in the CORE Client Certificates Folder on EP.
  • The client name is the hostname of EP.

Note
This command doesn't affect the partition's users and their credentials. To recover credentials of its SOSecurity officer - UKC partition administrator role., if needed, refer to CORE Password Reset.

Partition Quorum Reset

A partition quorum recovery resets the size of a partition quorum to the actual number of the partition SOs. Refer to ekm_recover_quorum. Use this script to recover quorum on any partition, including the root partition.
