Question

Unlock a CTRL-ALT-DELETE locked workstation using Smartcard PIN

Asked by: Sebastian_Strauss

We're planning to use smartcards to log into our workstations.
Unfortunately, it seems that once I'm logged into a workstation using my smartcard I don't
seem to be able to configure that I can unlock a CTRL-ALT-DELETE locked workstation
using my smartcard and PIN, instead of my AD username and password.

How can I configure it so it will let me use my smartcard and PIN to unlock a workstation?

Probably the smart card reader comes with a software that you can manage.

;)

Nah, the middleware doesn't change that part of the OS

The software I am familiar with is Active Card Gold use this in combination with the drivers for the card reader you have purchased.  Go into active directory and ensure that in place of the members username (i.e. first.last) it should read the 10 digit # that is tied with the CAC.  This number is your EDI-PI number that corresponds to the user's identity.  

Do you have Active Card gold installed on the machine?  I'm sure there are probably other applications similiar to this that might work but this is the one that I am familiar with.

tlbrittain, were you able to configure the OS to accept a card and PIN once you hit CTRL+ALT+DEL?

 

by: tlbrittainPosted on 2007-11-07 at 06:06:46ID: 20232112

The way it works is if you log in using username and password, when you lock the machine you then must use user/pass.  The same goes for Card/PIN.  If you are wanting your users to have to use only Smartcard authentication you will want to configure this in Active Directory.  It is in the same area where you re-enable/disable a user account, set the password to expire...I believe it is called "force smartcard authentication" or something like that.

No, that just defines that you want to log into the workstation using a PIN, instead of username and password. But even if you disallow username and password and require PIN instead, if you hit CTRL+ALT+DEL and try to unlock the workstation, it'll prompt you for your username and password. I don't seem to be able to force the PIN on that screen.

Maybe if Smardcard logon is forced the issue could be solved...else i don't see any other option

Generally speaking, if you are using a certificate on the SmartCard then you should be able to unlock the workstation - if not it is a bug, report it.

If the Smart Card is using a username/password stored on the card, then the vendor would need to have installed a GINA or GINA-shim (the shim being the more common, more compatible, and less intrusive method).  They would have already installed this for normal logon, but there are different ways to handle the different 'behind the scenes desktops', so to speak.  Again, this would be a bug - report it to the vendor.

The last thing to note is that there can be different ways of handling things when the user locks the workstation.  If they do it by using the 'lock workstation on card removal' policy setting, and then pull the card to lock then it should work fine.  If they, instead of pulling the card, use a keyboard method (windows+L, ctl-alt-del then lock workstation button, etc.) or disconnect a remote session, then the GiNA will act differently - this would not normally be considered to be a bug but there can be workarounds if the vendor is creative (if they do, find out how they do it to make sure that they are not using a hack workaround to give the illusion of 'fixing' this that you do not approve of...).

From the user standpoint, please understand that working with GiNA calls is very tricky stuff and requires heavy testing by the vendor, and usually a few days or more of research to find a fix.  This goes double if it involves a remote connection (RDP, terminal services, Citrix, etc) as there are latency/timing issues that mess with things as well.
