Intel® SCS Add-on 2.1 and SC2012 R2 ConfigMgr Integration (RCS Database mode) – Part 1


Active Directory and Certificates preparation for OOB

This part will cover Active Directory configuration and certificates requirements for OOB.

AD Configuration

  1. Create an new OU in Active Directory for AMT computers objects. ※If there are many domain, please create an OU in each domain
  2. Create an Universal security group to manage provisioned AMT compute accounts. Like “SC2012CM R2 AMT Computers”
  3. Create a user account, which will be used for AMT provisioning. Like “CM_AMT”
  4. Previously created user account should be local administrator on any computer, which will be provisioned. We recommend using Group Policy Preferences (GPP) to add that account to the local admin group of computers.
  5. Create a security group, which will contain AMT administrators. Like “SC2012CM R2 AMT Administrators”
  6. Add to the group created on step 5, previously created AMT account and the SCCM server computer account.
  7. Add the group created on step 5 in the security settings of the OU created on step 1. Provide “Full Control” on the OU.
  8. In the security tab of the group created on step 2, add the AMT administrators group created on step 5. Provide “Read” and “Write” permissions on it.

 

Certificates requirements

In this blog, we later use a certificate named “AMT Provisioning certificate”. This certificate has been issued by our Enterprise CA. In that case the hash of the Enterprise CA root certificate has to be manually registered on every computers in order them to be managed.

This step could be skipped if a public certificate is used for that purpose because PC’s firmware contains by default the root certificate hash of all known public certificate authorities. If you decide to use a public certificate, we recommend to follow procedures from the Intel SCS User Guide to request a public certificate.

Prerequisites

1.On the Certificate Service server, grant to the AMT account (CM_AMT) the following rights:

  • Issue and Manage Certificates

    Dear God, please come out with part 2.  I've been wrestling with RCS integration for months and this is the first ray of hope.

  2. Hey Andrew! was quite busy but just uploaded Part 2. Part 3 is coming in the next 2 days. Hope it helps.

    Is it possible to remote configure a workstation when using a local CA cert?

  4. Yes it is possible. If you're using a local CA cert, you have to follow the steps described in "Adding Enterprise Root CA certificate thumbprint into AMT computers" in the part 6 of that article 😉

    Instead of using the CM_AMT could the computer account of the SCCM primary site server be used?  If it and intel SCS are installed on the same system.

  6. Hi Mike! I have personally not tried it but I don't see why it wouldn't work wth the SCCM primaty site server account. Just add all the needed permissions to that computer account instead of CM_AMT account.

    We have OOB Service Point ,Enrollment Point on different server and SCCM Primary on different server. In that case :

    1. Should both the computer accounts  have permissions on  certificate or only primary site server?

    2. On which of these two servers should AMT Provisioning certificate be installed?

  8. @Divya if you follow the different part of my article, you will see that you need that AMT provisioning certificate in 3 different places: RCS server, Enrollment Point and OOB Service Point.

    In the part 1, we export the certificate in PFX format because we need later to import that certificate to the network service account used by RCS Server.

    In your case, you need to install the AMT Provisioning certificate on  your 3 servers: RCS Server, Enrollment Point and OOB Service Point. Thus you need to grand the "enroll" permissions to those 3 servers.

    Finally, you only need to export the certificate installed on the RCS Server, in order to re-import it to the network service account.
