Welcome to the post that shows how to configure Active Directory for LAPS.
The Bulk Modify dialog (pictured at the top of the page) will be displayed.
The dialog has been designed to look similar to the user dialog in Active Directory Users and Computers - this will make it easier for you to find the attributes you want to modify as the user interface is already familiar to you.
The Active Directory Schema needs to be extended by two new attributes that store the password of the managed local Administrator account for each computer and the time-stamp of password expiration.
We will update the Schema by importing the Power Shell module.
You will find that the textboxes that you normally use to enter information are disabled in the "Bulk Modify" user interface.
