The certificate chain could not be built. Intel SCS 12.2.0.150

Hello 

We are Using SCS to automatically deploy Intel AMT Configuration and Certificates. The AMT Devives, get their Config from a SCS Profile where the CA Server is available and a valid template is used. 

When a configuration request comes in the SCS builds the request and sends it to the CA. The CA sings the request and sends the certificate back. The SCS receives it and then fails to build the Chain with error: "The certificate chain could not be built. Please make sure that the root certificate is installed properly."

(Certificate ID: 4207431952).

So I checked all local certificates and all the Root and Intermediate CA certificates are stored as Trusted Root Certificates in the computer account. 

When I get a certificate with the same template via windows mmc the certificate is successfully installed. There were changes in the Root CA but not to the certificates itself. To be sure I also reinstalled the Root Certificates.

While checking everything there was something else I saw.

The RCS is Runnig as Network Service. When binding the Certificate (from another CA) to the RCS Server via RCSUtils. I get the message that they are added successfully but cannot view it.

Had the issue also with 12.2.139, so I decided to update. And now opening this case.

To my opinion it seems that either the certificates are not correctly set, eventough following the documentation. RCS is searching in the wrong stores for a Certificate or an Issue in the software itself.

What else can I check? Or are there Solutions to this issue?

Best Regards

Andy

Hello SysArch,


Thank you for joining the Intel community


First let me ask you what CA did you purchase the certificate from or if you are trying to use your own certificate. If the later is true then you want to follow the steps shown in the SCS User Guide section 10.5

https://www.intel.com/content/dam/support/us/en/documents/software/Intel_SCS_User_Guide.pdf#page=220


If not then let me know so we can further investigate on your issue

Hello Jose

Thank you for taking care of this issue.

We are using our own certificat for RCS which is setup by this guideline and added to the firmware of the devices. (The whole system has worked before)

As far as I understood this certificate is only for the secure communication between the AMT Client and RCS servers. So the clients can connect and start to receive their profile. It then fails when they request the certificate defined in the profile.

Thank you for your help.

Best regards,

Andy

Hello SysArch,


So what has changed recently since you say the whole system has worked before?

Please take a look at the following guide in order to add a certificate chain :

https://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide/default.htm?tu...


Let me know if it works

Hello Jose

Thank you for your Response. 

To clarify - we have 2 different CA's at Work.

1. CA-A which is providing the certificate for the RCS Server and is bound to the RCS Service. This CA was added to the Firmware of the AMT Devices. And as I interpreted this was the link you added

2. CA-B which is providing the certificates used by the AMT client by its web service (Configured via RCS Profile and automatically deployed via microsoft CA)

There was a update of the crl in CA-B (Not the URL - but the CRL itself)

May I share a full log file with you in private?

All the best

Andy
