Pushing down certificates using AD into user personal certificate store

Hi Experts,

How can we push a third party client authentication certificate (used for 2 way SSL) using AD to a user's personal certificate store?

Yes. Certificates in the user's personal store are just registry keys, so can be pushed using group policy.

HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates

(system certificates are in a similar place on HKLM)

note, these are just the certificates, not including private keys.

So where do I keep the certificates in this case?

pfx files? probably on the NETLOGON administrative share on the domain controllers (which is the classic location for login scripts and their attendant administrivia)

Why sould you ever see user's provate key? Why you want  to compromise your security by issuing users your private keys?

@gheist:
  There are times that is advisable - certainly, if the key is used for business purposes, you will want a recovery mechanism in place in case the device crashes, the employee leaves or any other case where the employee is unwilling or unable to unlock data secured to that key.

  None of that prevents the user creating and using their own keys for private/personal purposes.

Here's how I do it:

Create a share and place capicom.dll and cstore.vbs in it

Then a logon script with the following

@ECHO OFF
if exist c:\windows\system32\capicom.dll goto next
:copy
copy "\\server\certificates\capicom.dll" "C:\windows\system32\"
:next
regsvr32  /s capicom.dll
cscript \\server\certificates\CStore.vbs import \\server\certificates\cert1.pfx P@ssword
cscript \\server\certificates\CStore.vbs import \\server\certificates\cert2.pfx P@ssw0rd
