STEPS TO REPRODUCE 1. open user manager 2. observe the current state (checked/unchecked) of both "Enable administrator privileges for this user" and "Log in automatically" checkboxes on bottom 3. change the state of any of them 4. click on "Apply" button 5. cancel the password dialog OBSERVED RESULT state of the checkbox clicked in the step 3 is wrong, falsely indicating that the change was applied. EXPECTED RESULT after the password dialog to be cancelled, the state of the checkbox should be the one observed in the step 2.
