My enterprise has the "This device is the property of ..." screen enabled with a single OK button before the sign-in screen where user name and PW can be entered.
Since 10.7.2 (1953), the app doesn't provide the password and the login halts at the sign-in screen with the user name populated, but the PW blank. This is new behavior, the version I had before (Maybe 10.7.2 (1952)? Not sure, didn't capture that when I upgraded yesterday.)
The production client (10.7.1 (1945)) works fine with the same host.
