The UI is pretty straight forward. It asks for the group name, the scope and the owner.
When the Verify Group button is pressed, we perform a few checks before we create the groups. First we check to see if there are similar groups. In this case, the panel is now visible and the status bar indicates that like groups already exist.
Once we verify the group name, we need to verify that the entered group owner is in fact a legitimate AD object.
In this case, the user is not valid. Once all the data is verified, we give the user one last chance to cancel before the groups are created.
That's about it!
