Global Protect client certificate auth Current User Vs Local Computer Store

Having some trouble with a generalized  single certificate (wanting to use as part of user/pass authentication)  across multiple machines.  Wanting to require this certificate be on a machine and the user enter their user/pass combination for authentication to portal/gateway (not user/machine specific cert).  Not doing prelogon at this point.    I can add this exported certificate into the Certificates (Local Computer) /Personal AND Trusted Root store ....all day long....and it makes no difference.   

I can even specify in the portal agent config to use 1.3.6.1.5.5.7.3.2 for an OID- and also ensure that both  Client certificate store look up - both "user and machine" is set on the portal...still nothing.

 

The only way I can get this to successfully work, is by placing the exported certificate into the Certificates -Current User - personal - store. ...then everything works perfectly.    It's almost as if windows clients have issues accessing the machine store when a user is logged in?  Anyone have experience with this, or something along these lines?

 

Maybe @MickBall  answered part of this already below:

MS seems to hint at the fact that any machine store cert in the trusted root will be mirrored to the current user store trusted root- but NOT the Current User Personal:

 

https://docs.microsoft.com/en-us/windows-hardware/drivers/install/local-machine-and-current-user-cer...

"Be aware that all current user certificate stores except the Current User/Personal store inherit the contents of the local machine certificate stores."

 

 

Does a generic certificate have to be installed for every user under their current user personal certificate store?

No, generic certificates do not have to be in the users personal store..

 

Have you set the GP app to use both user and computer certs.

@MickBall  Are you referring to the "client certificate store lookup" - both user and machine ? -  If so, yes, I have that specified.      This is not for pre-logon- only when the user is logged on.  Thank you for the quick reply. Never hurts to have more input.

OK worth a check..

 

I use certs in the computer store and it works fine for when users are logged into the device.

I also do not use pre-logon.

 

with the certificate located in the computer/personal/certificates area  have you tried browsing vi IE to your portal.

this may throw up a more helpful error than the portal.

Access to the machine cert store is not available to standard user accounts. It requires elevated permissions. Not sure if GP can get around this if a user is already logged in to the machine. 

@MickBall , do your users have admin rights on the workstation?

@rmfalconer , hi.

nope, admin level access is used to install the cert but our users are restricted to the hilt.

Browsing to the Portal will throw the same error- "client certificate required"-   it's like it doesn't see the cert at all....but the second I move it to the current user store---everything works....

 

 

I'm hearing that people have these certs in their machine stores, but I have yet to get this to successfully work

I am starting to wonder about this, as I cannot get it to successfully work

@MickBall -

 

That certificate is not used for pre-logon, or installed in the personal store right?

L6 Presenter

Re: Global Protect client certificate auth Current User Vs Local Computer Store

No the certificate is not in the users personal store.

 

for a small group of user, about 250, we cannot use the personal store. So we use the computer store.

 

i will check AD permissions tomorrow to see if @rmfalconer  has seen something more obvious here.
