Adding an existing user to a new group

If you'd like to give an existing user access to your software, you'll need a way to reference their account and then add it to the group you're creating. For example, user Alice already exists on the system and you'd like to add her to a new group called Supervisors. As a side note, you would typically ask for that username through a UI wizard. Then, save the username to a WiX property. Properties can be accessed in other elements by using a square bracket notation, as follows:

<util:User Id="myNewUser" Name="[USERNAME]" />

The UtilExtension namespace doesn't include an element to create a new group. So, we'll return to Community MSI Extensions. In this recipe, we'll locate an existing user account and add it to our Supervisors group.
