Since we have nearly as many disabled users in IDM as enabled, we need to see their status on the search screen results. It shows 0 or 1 as a String, but not as a checkbox.
In Modify Admin Task make sure that the Read-Only Checkbox Field Properties are set.
In "Select the fields that appear in the search results," click the pencil icon to the right of the enable attribute Read-Only Checkbox and specify the checked and unchecked values, 1 and 0 respectively.
