When the desktop goes to lockscreen, in order to unlock I may [see IMG_20150423_182816.jpg attached]: 1. Use my right ldap password: Unlock successfully; 2. Use a wrong ldap password: It doesn't unlock, showing an error message; 3. Don't use any password, just press "Enter": Unlock successfully! This is a serious security failure. One unauthorized person walking around could access a machine and use it.
