Is it possible to hide the create a copy of a user option in CA IDM?
You can do this by going to Roles and tasks > Admin Tasks > Modify Admin Tasks > Create User
Once in the modify create user page, you can go to the search tab and hit the clear button next to the Search Screen option. Save this and hit submit.
This will remove the search screen, so when you create a new user it will skip the search and automatically put you directly onto the task.
