Copy Active Directory user group membership

Sometimes when a new user is added to a team he or she needs all, or a selection of the Active Directory groups his colleagues are member of. Unfortunately, this can’t be done with the native Active Directory tools. To overcome this, I made a Powershell script to (selectively) copy Active Directory user group membership from one user to another.

What the script does

The script will ask you for a source and destination user to copy group membership information to.

Let’s copy the groups Donald Duck (dduck) is member of to Katrien (Daisy) Duck (Kduck).


Next you will be presented an overview of the group membership from the source user and to which groups the destination user will be added.


If you copy [A]ll groups from the source to the destination user, the script exits with the message “Group information copied from <source user> to <destination user>”.


If you want to copy some of the groups (not all) to the destination user press [S]elect.


A GUI will popup where you are able to multi select the groups to copy.

After pressing “OK” a summary of the added groups will be displayed.

Save the script to Conf-UserGroupMembership.ps1. Run the script on a server where the “Active Directory module for Windows Powershell” is installed. Happy copying 🙂
