KB-1357: screensaver failed to unlock

Auditing and Monitoring Service ,   Authentication Service ,   Mac & PC Management Service ,

Applies to: DirectControl 4.4 EA on Mac


If you have the system set to password lock at screen saver you can not unlock it with AD credentials.

The reason is that unlocking screen saver is now done via PAM. There is a /etc/pam.d/screensaver file. 
Unfortunately, Apple does not pass in PAM_CONV structure so adclient does not get a chance to fill in AD user password, thus PAM
authenticates the user with an empty password which results in pre-authentication error.

Login with local administrator account, bring up terminal and execute the below commands:
sudo mv /etc/pam.d/screensaver /etc/pam.d/screensaver.cdc
sudo cp /etc/pam.d/screensaver.pre_cdc /etc/pam.d/screensaver

Fixed in DirectControl 4.4
