tis-laps-by-wapt

This guide explains how to retrieve the local administrator password generated by the tis-laps-by-wapt package.

Instructions

Steps to Retrieve the Password

  1. Deploy the Package Install the tis-laps-by-wapt package on:

    • The target Organizational Unit (OU), or
    • The individual machines concerned.

  2. Access Audit Data

    • In the WAPT Console, select a machine where the tis-laps-by-wapt package is installed.
    • In the right panel, navigate to the « Audit Data » tab.

  3. Locate the LAPS Section

    • Find the row where the « Section » column contains the value « laps ».

  4. Identify the Password Key

    • The associated key is named « local_admin_password ».
    • If the « Decrypt Data » option is not checked, the displayed value will be encrypted in the following format: 
      -----BEGIN WAPT ENCRYPTION-----
{"XXXXXX"}
-----END WAPT ENCRYPTION-----

  5. Decrypt the Value

    • Check the « Decrypt Data » option to display the password in plaintext.
    • Condition: Your WAPT certificate must be correctly configured on the machine for decryption to work.

Important Notes

  • Decryption requires the WAPT certificate to be present and valid on the machine.
  • If the certificate is missing or invalid, the value will remain encrypted.
