Switching between input fields on the SSO login page (login name, password, remember me, and login button) does not work correctly in the Safari and Chrome browser on Mac OS X.
Expected behavior is that after pressing the Tab key, the focus will go to the next input field (in order username -> password -> remember me -> login button).
It works OK for the switching from the username to the password field, but then it differs:

In Safari, the focus goes from the password field to the browser's address line, and then (on next tab-key press) back to the username field.

In Chrome (Mac OS X), the focus goes correctly, but is invisible - so if you press Tab key in the password field, the focus "disappears", but then if you press space, the "remember me" field gets checked. That's perhaps a problem in Chrome.

Firefox (14.0.1) works as expected.
