Login experience is not accessible

[nkkl]

When logging into a Mac with JAMF Pro running, you must enter your credentials, accept a warning, accept another warning, and then enter your credentials again, before being able to access your device. The second warning screen can only be interacted with using a mouse/trackpad, which is a definite accessibility problem as not all users can use a pointing device (ex. someone with visual impairments or motor problems).

Note that this violates Section 508 and WCAG 2.0 AA standards – which we're required to follow by law.

The second warning screen can be confirmed by pressing the return (enter) key on the keyboard.

@vanbella I tried a few different conditions, and got different results under different circumstances. Here's what I found:

• Use only keyboard to navigate login screen and enter credentials
  • Warning screen has correct focus and can be cleared by pressing enter
• Use pointing device to navigate login screen
  • Warning screen does not have focus and cannot be cleared by pressing enter
  • This scenario indicates that the user has a pointing device and can use it, so the warning modal losing focus is technically still a bug but very low priority
• Use keyboard to navigate login screen, but move mouse without clicking (ex. if a nonsighted user brushed the trackpad)
  • Warning screen has focus and can be cleared by pressing enter
• Use keyboard to navigate login screen, but click mouse on background (ex. if a nonsighted user accidentally pressed down on the trackpad)
  • Warning screen loses focus and cannot be cleared by pressing enter
  • This is a bug; I'm not sure how likely it is to occur, but if a user gets into this state they are trapped and cannot exit it without using a pointing device
  • If I had to guess, I would probably call this a Severity 2, Priority 2–3 bug

I'm not really sure why the warning modal loses focus if you click (anywhere); that seems incorrect. It does behave correctly if there are no mouse clicks at all.
