If you need to deploy the Microsoft LAPS schema, refer to the Microsoft guides on how to complete this process.
Password retrieval
Enable retrieval of legacy LAPS passwords
When configured, Access Manager will attempt to retrieve passwords stored in Active Directory stored by the legacy Microsoft LAPS agent.
Enable retrieval of Windows LAPS passwords
When configured, Access Manager will attempt to retrieve passwords stored in Active Directory stored by the new Windows LAPS agent in either encrypted or unencrypted form.
This includes the ability to read encrypted passwords, as well as password history from Active Directory.
Permissions
If you plan on using Lithnet Access Manager to read Microsoft LAPS passwords, you'll need to delegate permission for the AMS service account to read those passwords. You can use the built-in cmdlets from Microsoft's PowerShell modules, or click the Delegate LAPS Permissions button to generate a script to do this automatically.
Copy or save the script, modify the $OU variable as appropriate, and run it in with domain admin rights.
