Q: What happened to my login page after display sleep?

I'm not sure what happened but whenever my display goes to sleep and I click the trackpad to turn it back on, a dialog box shows up asking for my password. Prior to two days ago, when I woke the display the login screen would pop up with my user icon (just like the initial login screen, but without Guest), but now it's just the dialog box with a black screen. Anyone have any idea how this happened, or how to get it back to the way it was? I'm running OSX 10.8.4.

MacBook Pro, OS X Mountain Lion (10.8.4)

A:

I recently met this problem, and I finally managed to get it "repaired". Here's the problem and the solution

 

I met the problem after I installed "smart card services". I reviewed the installation process, and found an option entitled "cacloginconfig" . Here is the description:

This 'default' Property List file (CACLoginConfig.plist) is used by both the "Attribute Matching" and "PKINIT (SSO)" scenarios for Smart Card Services setup.

This file is necessary if you are binding your Smart Card to either:  (A) a Local OS X Account (Attribute Matching)  (B) Active Directory with Smart Card Login for SSO (PKINIT)

The existence of this file will switch OS X from using the built-in default "PubKeyHash" method to mapping Attribute(s) instead.  If this file is deleted or missing on the OS X system, it will revert back to the "PubKeyHash" method for binding a Smart Card to a particular account. the command "sc_auth" is provided on OS X for managing the PubKeyHash usage for accounts.

The contents of this file will configure the desired mapping of supported certificate attribute(s) to a single DS attribute lookup (i.e. Mapping the "NT Principal Name" from the Certificate to the single AD attribute "userPrincipalName").  This is a default property list file that should be modified if required by your DS setup.

The attribute(s) are drawn from your Smart Card based certificate containing  "Smartcard Logon ( 1.3.6.1.4.1.311.20.2.2 )"  for "Extended Key Usage ( 2.5.29.37 )".

I looked into this bundle, and learned that a plist file named "cacloginconfig.plist" was installed to /etc due to this option. Finally, I executed

 

sudo mv /etc/cacloginconfig.plist /etc/cacloginconfig.plist.bak

 

and everything went back as normal.

 

Hope the solution can help you.

    I remember once to have a smart card service installed as well. And even though I removed it, since then I get a login window like you used to have. Still, I can't fix it trying your approach (there is no

    cacloginconfig.plist

    in /etc) Is there another location where I could have a look to delete this file? I already tried a spotlight search with no success.

    Thank you! I know this is an old post, but I was having the black background issue as well. This prevented my Apple Watch from completing Auto Unlock and it was driving me crazy trying to figure out which obscure option I may have checked that was interfering.

     

    For anybody who stumbles up on this post from Google...

    The post above fixed the issue with Apple Watch Auto Unlocking immediately after moving the file. No restart necessary.
