I see this on systems with LDAP, and systems without. It's just happened on this machine, which is built from scratch about 1 week ago. It's with a new user - so all the user config is as created by a new clean Ubuntu system. I haven't customised PAM at all.
I see lots of failures in auth.log, but none of them are specific to this condition.

The shaded gray area simply does not have the input field. I can't do anything, I have to switch to text console and stop/start lightdm service to cure the problem loosing all of my session :( ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: unity 7.2.0+14.04.20140416-0ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-24.46-generic 3.13.9 Uname: Linux 3.13.0-24-generic i686 ApportVersion: 2.14.1-0ubuntu3 Architecture: i386 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CurrentDesktop: Unity Date: Tue Apr 22 22:17:57 2014 InstallationDate: Installed on 2012-03-03 (780 days ago) InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release i386 (20110427.1) SourcePackage: unity UpgradeStatus: Upgraded to trusty on 2013-10-18 (186 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1311316/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
