Summary:
When trying to unlock the computer after sleep (and possibly screensaver), the unlock dialog intermittently refuses to unlock the computer.

There's no "invalid password shake" or error message - I am able to enter my password fine, but when I press enter or click the little arrow for "log in", nothing happens except the contents of the password field getting selected. Pressing "escape" or clicking the "Cancel" button does nothing - it stays on the unlock screen. Waiting for 10 minutes does nothing.

Only way to get in seems to be to do a hard shutdown via a long press on the power button.


Steps to Reproduce:
1. Sleep (or lock?) computer
2. Attempt to unlock

Expected Results:
- Machine should unlock or tell me I'm entering the wrong password

Actual Results:
- Nothing

Regression:
- Did not experience these issues on 10.7

Notes:
Account is a "managed" mobile account (admin) on the machine with an associated apple id (using AD integration). I've attached a log of lines from the log at the time of the failed logins - similar entries occur each time.
