Deployment

For initial deployment of Escrow Buddy, Iru (formerly known as Kandji) administrators can follow this template:

Library Item: FileVault

Ensure the Escrow Recovery Keys to Iru option is enabled. See this KB article for details.

NOTE: Enabling this option will present a FileVault Recovery Key "action" in the Iru menu item. Users can either log out and let Escrow Buddy generate a new key silently upon next login, or they can follow the prompt in the Iru menu to generate a new key by providing their password. Either way, the result will be the same: the new key will be escrowed to Iru.

Library Item: Custom App: Escrow Buddy

This library item installs Escrow Buddy.

• Custom App Name: Escrow Buddy

• Assignment Rules: One or more Mac blueprints

• Execution Frequency: Audit and enforce

  • Audit Script:

    #!/bin/bash
    BUNDLE_PATH="/Library/Security/SecurityAgentPlugins/Escrow Buddy.bundle"

• Package: Latest Escrow Buddy package downloaded from this page

• Restart after successful install: No

See this Iru KB for details.

To resolve this with Iru, you can use the following:

HELP WANTED: If you're an Iru admin, please consider contributing to this section. The ideal solution would be an audit script that detects authdb status, and a remediation script that re-runs AuthDBSetup.sh if needed.

Removal

To uninstall Escrow Buddy using Iru, you can use a once-per-computer Library Item with the uninstall script here attached.
