Client Management ID

[SK233]

This might be a stupid question but here goes.

I'm looking to use LAPS with Jamf and I can't seem to find the "ClientManagementID"  for the API call.

/v2/local-admin-password/{clientManagementId}/account/{username}/password

Any help will be appreciated

Thanks in advance.

This will tell you what you need to know to find it. It takes a few steps.

How to Securely Manage Local Admin Passwords with Jamf Pro and LAPS

How do i create an Extension Attribute to populate the Mac's "managementid" so that we can view the managementid from the Mac General view in Jamf Pro?

So we had some issues with Apple Silicon machines not liking the admin password from the laps feature, and these machines stopped granting volume ownership properly and are keeping us from allowing those users to perform updates.  (we use the erase and install script).  Once I ran through the api call to reset the laps password on the individual machine back to what it was, then the machine granted volume ownership to the standard user.  Do you know of a script thats been made that does what you suggested in your great article in the last paragraph: "While Jamf Pro offers a PUT /v2/local-admin-password/{clientManagement}/set-password endpoint, it’s only available to set one computer at a time. The Jamf Pro administrator will need to create a Jamf Pro API script to set every computer password using LAPS. Only after ensuring all passwords are changed to known passwords should the administrator turn off LAPS"?

For us to move forward I would need a script to hit each machine (looking up each management id for a smart group).

Came up with a script that can reset the laps passwords to a manual one scoped by a smart group.

This has alleviated the volume ownership issues we were having on Apple Silicon Machines and let us set a password for the time being.  Hope this helps someone else out there:
