Hello,
Thank you so much for posting here.
The "Local Administrator Password Solution" (LAPS) provides management of local account passwords of domain joined computers. For more information, we could refer to: https://www.microsoft.com/en-us/download/details.aspx?id=46899&Search=true
As per my understanding, we would like to manage local admin accounts centralized. If so, we will put all the clients and machines into a OU and then manage the local admin account using restricted group via Group Policy. Then the policy will be applied to all the clients and machines within the OU.
But as per our description, it seems that different clients and machines will have different local admin accounts management. If so, I think we might create different OU for the machines and then configure different GPOs.
Please let me know if there is any misunderstanding. For any question, please feel free to contact us.
Best regards,
Hannah Xiong
