Step-by-Step Example Deployment of the PKI Certificates for Configuration Manager: Windows Server 2008 Certification Authority

Updated: March 1, 2013

Applies To: System Center 2012 Configuration Manager, System Center 2012 Configuration Manager SP1, System Center 2012 R2 Configuration Manager

This step-by-step example deployment, which uses a Windows Server 2008 certification authority (CA), contains procedures to guide you through the process of creating and deploying the public key infrastructure (PKI) certificates that Microsoft System Center 2012 Configuration Manager uses. These procedures use an enterprise certification authority (CA) and certificate templates. The steps are appropriate for a test network only, as a proof of concept.

Because there is no single method of deployment for the required certificates, you must consult your particular PKI deployment documentation for the required procedures and best practices to deploy the required certificates for a production environment. For more information about the certificate requirements, see PKI Certificate Requirements for Configuration Manager.

TipTip
The instructions in this topic can easily be adapted for operating systems other than the ones documented in the Test Network Requirements section. However, if you are running the issuing CA on Windows Server 2012, you are not prompted for the certificate template version. Instead, specify this on the Compatibility tab of the template properties, as follows:

  • Certification Authority: Windows Server 2003

  • Certificate recipient: Windows XP / Server 2003

The step-by-step instructions have the following requirements:

  • The test network is running Active Directory Domain Services with Windows Server 2008, and it is installed as a single domain, single forest.

  • You have a member server running Windows Server 2008 Enterprise Edition, which has installed on it the Active Directory Certificate Services role, and it is configured as an enterprise root certification authority (CA).

  • You have one computer that has Windows Server 2008 (Standard Edition or Enterprise Edition) installed on it and that is designated as a member server, and Internet Information Services (IIS) is installed on it. This computer will be the Configuration Manager site system server that you will configure with an intranet FQDN (to support client connections on the intranet) and an Internet FQDN if you must support mobile devices that are enrolled by Configuration Manager and clients on the Internet.

  • You have one Windows Vista client with the latest service pack installed, and this computer is configured with a computer name that comprises ASCII characters and is joined to the domain. This computer will be a Configuration Manager client computer.

  • You can log in with a root domain administrator account or an enterprise domain administrator account and use this account for all procedures in this example deployment.

The following table lists the types of PKI certificates that might be required for System Center 2012 Configuration Manager and describes how they are used.

 

Certificate Requirement Certificate Description

Web server certificate for site systems that run IIS

This certificate is used to encrypt data and authenticate the server to clients. It must be installed externally from Configuration Manager on site systems servers that run IIS and that are configured in Configuration Manager to use HTTPS.

For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: This certificate might also be required on management points when client notification traffic falls back to using HTTPS.

For the steps to configure and install this certificate, see Deploying the Web Server Certificate for Site Systems that Run IIS in this this topic.

Service certificate for clients to connect to cloud-based distribution points

For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only:

This certificate is used to encrypt data and authenticate the cloud-based distribution point service to clients. It must be requested, installed, and exported externally from Configuration Manager so that it can be imported when you create a cloud-based distribution point.

For the steps to configure and install this certificate, see Deploying the Service Certificate for Cloud-Based Distribution Points in this this topic.

noteNote
This certificate is used in conjunction with the Windows Azure management certificate. For more information about the management certificate, see How to Create a Management Certificate and How to Add a Management Certificate to a Windows Azure Subscription in the Windows Azure Platform section of the MSDN Library.

Client certificate for Windows computers

This certificate is used to authenticate Configuration Manager client computers to site systems that are configured to use HTTPS. It can also be used for management points and state migration points to monitor their operational status when they are configured to use HTTPS. It must be installed externally from Configuration Manager on computers.

For the steps to configure and install this certificate, see Deploying the Client Certificate for Windows Computers in this topic.

Client certificate for distribution points

This certificate has two purposes:

  • The certificate is used to authenticate the distribution point to an HTTPS-enabled management point before the distribution point sends status messages.

  • When the Enable PXE support for clients distribution point option is selected, the certificate is sent to computers that PXE boot so that they can connect to a HTTPS-enabled management point during the deployment of the operating system.

For the steps to configure and install this certificate, see Deploying the Client Certificate for Distribution Points in this topic.

Enrollment certificate for mobile devices

This certificate is used to authenticate Configuration Manager mobile device clients to site systems that are configured to use HTTPS. It must be installed as part of mobile device enrollment in Configuration Manager and you select the configured certificate template as a mobile device client setting.

For the steps to configure this certificate, see Deploying the Enrollment Certificate for Mobile Devices in this topic.

Certificates for Intel AMT

There are three certificates that relate to out of band management for Intel AMT-based computers: An AMT provisioning certificate; an AMT web server certificate; and optionally, a client authentication certificate for 802.1X wired or wireless networks.

The AMT provisioning certificate must be installed externally from Configuration Manager on the out of band service point computer, and then you select the installed certificate in the out of band service point properties. The AMT web server certificate and the client authentication certificate are installed during AMT provisioning and management, and you select the configured certificate templates in the out of band management component properties.

For the steps to configure these certificates, see Deploying the Certificates for AMT in this topic.

Client certificate for Mac computers

For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only:

This certificate is used to authenticate Configuration Manager SP1 Mac computers to management points and distribution points that are configured to support HTTPS.

You can request and install this certificate from a Mac computer when you use Configuration Manager enrollment and select the configured certificate template as a mobile device client setting.

For the steps to configure this certificate, see Deploying the Client Certificate for Mac Computers in this topic.

This certificate deployment has the following procedures:

  • Creating and Issuing the Web Server Certificate Template on the Certification Authority

  • Requesting the Web Server Certificate

  • Configuring IIS to Use the Web Server Certificate

This procedure creates a certificate template for Configuration Manager site systems and adds it to the certification authority.

  1. Create a security group named ConfigMgr IIS Servers that contains the member servers to install System Center 2012 Configuration Manager site systems that will run IIS.

  2. On the member server that has Certificate Services installed, in the Certification Authority console, right-click Certificate Templates and click Manage to load the Certificate Templates console.

  3. In the results pane, right-click the entry that displays Web Server in the column Template Display Name, and then click Duplicate Template.

  4. In the Duplicate Template dialog box, ensure that Windows 2003 Server, Enterprise Edition is selected, and then click OK.

    ImportantImportant
    Do not select Windows 2008 Server, Enterprise Edition.

  5. In the Properties of New Template dialog box, on the General tab, enter a template name to generate the web certificates that will be used on Configuration Manager site systems, such as ConfigMgr Web Server Certificate.

  6. Click the Subject Name tab, and make sure that Supply in the request is selected.

  7. Click the Security tab, and remove the Enroll permission from the security groups Domain Admins and Enterprise Admins.

  8. Click Add, enter ConfigMgr IIS Servers in the text box, and then click OK.

  9. Select the Enroll permission for this group, and do not clear the Read permission.

  10. Click OK, and close the Certificate Templates Console.

  11. In the Certification Authority console, right-click Certificate Templates, click New, and then click Certificate Template to Issue.

  12. In the Enable Certificate Templates dialog box, select the new template that you have just created, ConfigMgr Web Server Certificate, and then click OK.

  13. If you do not need to create and issue any more certificate, close Certification Authority.

This procedure allows you to specify the intranet and Internet FQDN values that will be configured in the site system server properties, and then installs the web server certificate on to the member server that runs IIS.

  1. Restart the member server that runs IIS, to ensure that the computer can access the certificate template that you created, by using the Read and Enroll permissions that you configured.

  2. Click Start, click Run, and type mmc.exe. In the empty console, click File, and then click Add/Remove Snap-in.

  3. In the Add or Remove Snap-ins dialog box, select Certificates from the list of Available snap-ins, and then click Add.

  4. In the Certificate snap-in dialog box, select Computer account, and then click Next.

  5. In the Select Computer dialog box, ensure Local computer: (the computer this console is running on) is selected, and then click Finish.

  6. In the Add or Remove Snap-ins dialog box, click OK.

  7. In the console, expand Certificates (Local Computer), and then click Personal.

  8. Right-click Certificates, click All Tasks, and then click Request New Certificate.

  9. On the Before You Begin page, click Next.

  10. If you see the Select Certificate Enrollment Policy page, click Next.

  11. On the Request Certificates page, identify the ConfigMgr Web Server Certificate from the list of displayed certificates, and then click More information is required to enroll for this certificate. Click here to configure settings.

  12. In the Certificate Properties dialog box, in the Subject tab, do not make any changes to the Subject name. This means that the Value box for the Subject name section remains blank. Instead, from the Alternative name section, click the Type drop-down list, and then select DNS.

  13. In the Value box, specify the FQDN values that you will specify in the Configuration Manager site system properties, and then click OK to close the Certificate Properties dialog box.

    Examples:

    • If the site system will only accept client connections from the intranet, and the intranet FQDN of the site system server is server1.internal.contoso.com: Type server1.internal.contoso.com, and then click Add.

    • If the site system will accept client connections from the intranet and the Internet, and the intranet FQDN of the site system server is server1.internal.contoso.com and the Internet FQDN of the site system server is server.contoso.com:

      1. Type server1.internal.contoso.com, and then click Add.

      2. Type server.contoso.com, and then click Add.

      noteNote
      It does not matter in which order you specify the FQDNs for Configuration Manager. However, check that all devices that will use the certificate, such as mobile devices and proxy web servers, can use a certificate SAN and multiple values in the SAN. If devices have limited support for SAN values in certificates, you might have to change the order of the FQDNs or use the Subject value instead.

  14. On the Request Certificates page, select ConfigMgr Web Server Certificate from the list of displayed certificates, and then click Enroll.

  15. On the Certificates Installation Results page, wait until the certificate is installed, and then click Finish.

  16. Close Certificates (Local Computer).

This procedure binds the installed certificate to the IIS Default Web Site.

  1. On the member server that has IIS installed, click Start, click Programs, click Administrative Tools, and then click Internet Information Services (IIS) Manager.

  2. Expand Sites, right-click Default Web Site, and then select Edit Bindings.

  3. Click the https entry, and then click Edit.

  4. In the Edit Site Binding dialog box, select the certificate that you requested by using the ConfigMgr Web Server Certificates template, and then click OK.

    noteNote
    If you are not sure which is the correct certificate, select one, and then click View. This allows you to compare the selected certificate details with the certificates that are displayed with the Certificates snap-in. For example, the Certificates snap-in displays the certificate template that was used to request the certificate. You can then compare the certificate thumbprint of the certificate that was requested with the ConfigMgr Web Server Certificates template with the certificate thumbprint of the certificate currently selected in the Edit Site Binding dialog box.

  5. Click OK in the Edit Site Binding dialog box, and then click Close.

  6. Close Internet Information Services (IIS) Manager.

The member server is now provisioned with a Configuration Manager web server certificate.

ImportantImportant
When you install the Configuration Manager site system server on this computer, make sure that you specify the same FQDNs in the site system properties as you specified when you requested the certificate.

noteNote
The service certificate for cloud-based distribution points applies to Configuration Manager SP1 only.

This certificate deployment has the following procedures:

This procedure creates a custom certificate template that is based on the Web Server certificate template. The certificate is for Configuration Manager cloud-based distribution points and the private key must be exportable. After the certificate template is created, it is added to the certification authority.

noteNote
This procedure uses a different certificate template from the web server certificate template that you created for site systems that run IIS, because although both certificates require server authentication capability, the certificate for cloud-based distribution points requires you to enter a custom-defined value for the Subject Name and the private key must be exported. As a security best practice, do not configure certificate templates to allow the private key to be exported unless this configuration is required. The cloud-based distribution point requires this configuration because you must import the certificate as a file, rather than select it from the certificate store.

By creating a new certificate template for this certificate, you can restrict which computers request a certificate that allows the private key to be exported. On a production network, you might also consider adding the following modifications for this certificate:

  • Require approval to install the certificate, for additional security.

  • Increase the certificate validity period. Because you must export and import the certificate each time before it expires, increasing the validity period reduces how often you must repeat this procedure. However, when you increase the validity period, it decreases the security of the certificate because it provides more time for an attacker to decrypt the private key and steal the certificate.

  • Use a custom value in the certificate Subject Alternative Name (SAN) to help identify this certificate from standard web server certificates that you use with IIS.

  1. Create a security group named ConfigMgr Site Servers that contains the member servers to install System Center 2012 Configuration Manager SP1 primary site servers that will manage cloud-based distribution points.

  2. On the member server that is running the Certification Authority console, right-click Certificate Templates, and then click Manage to load the Certificate Templates management console.

  3. In the results pane, right-click the entry that displays Web Server in the column Template Display Name, and then click Duplicate Template.

  4. In the Duplicate Template dialog box, ensure that Windows 2003 Server, Enterprise Edition is selected, and then click OK.

    ImportantImportant
    Do not select Windows 2008 Server, Enterprise Edition.

  5. In the Properties of New Template dialog box, on the General tab, enter a template name to generate the web server certificate for cloud-based distribution points, such as ConfigMgr Cloud-Based Distribution Point Certificate.

  6. Click the Request Handling tab, and select Allow private key to be exported.

  7. Click the Security tab, and remove the Enroll permission from the Enterprise Admins security group.

  8. Click Add, enter ConfigMgr Site Servers in the text box, and then click OK.

  9. Select the Enroll permission for this group, and do not clear the Read permission.

  10. Click OK and close Certificate Templates Console.

  11. In the Certification Authority console, right-click Certificate Templates, click New, and then click Certificate Template to Issue.

  12. In the Enable Certificate Templates dialog box, select the new template that you have just created, ConfigMgr Cloud-Based Distribution Point Certificate, and then click OK.

  13. If you do not have to create and issue any more certificates, close Certification Authority.

This procedure requests and then installs the custom web server certificate on to the member server that will run the site server.

  1. Restarted the member server after you created and configured the ConfigMgr Site Servers security group to ensure that the computer can access the certificate template that you created, by using the Read and Enroll permissions that you configured.

  2. Click Start, click Run, and type mmc.exe. In the empty console, click File, and then click Add/Remove Snap-in.

  3. In the Add or Remove Snap-ins dialog box, select Certificates from the list of Available snap-ins, and then click Add.

  4. In the Certificate snap-in dialog box, select Computer account, and then click Next.

  5. In the Select Computer dialog box, ensure Local computer: (the computer this console is running on) is selected, and then click Finish.

  8. Right-click Certificates, click All Tasks, and then click Request New Certificate.

  9. On the Before You Begin page, click Next.

  10. If you see the Select Certificate Enrollment Policy page, click Next.

  11. On the Request Certificates page, identify the ConfigMgr Cloud-Based Distribution Point Certificate from the list of displayed certificates, and then click More information is required to enroll for this certificate. Click here to configure settings.

  12. In the Certificate Properties dialog box, in the Subject tab, for the Subject name, select Common name as the Type.

  13. In the Value box, specify your choice of service name and your domain name by using an FQDN format. For example: clouddp1.contoso.com.

    noteNote
    It does not matter what service name you specify, as long as it is unique in your namespace. You will use DNS to create an alias (CNAME record) to map this service name to an automatically generated identifier (GUID) and an IP address from Windows Azure.

  14. Click Add, and click OK to close the Certificate Properties dialog box.

  15. On the Request Certificates page, select ConfigMgr Cloud-Based Distribution Point Certificate from the list of displayed certificates, and then click Enroll.

  16. On the Certificates Installation Results page, wait until the certificate is installed, and then click Finish.

  17. Close Certificates (Local Computer).

This procedure exports the custom web server certificate to a file, so that it can be imported when you create the cloud-based distribution point.

  1. In the Certificates (Local Computer) console, right-click the certificate that you have just installed, select All Tasks, and then click Export.

  2. In the Certificates Export Wizard, click Next.

  3. On the Export Private Key page, select Yes, export the private key, and then click Next.

    noteNote
    If this option is not available, the certificate has been created without the option to export the private key. In this scenario, you cannot export the certificate in the required format. You must reconfigure the certificate template to allow the private key to be exported, and then request the certificate again.

  4. On the Export File Format page, ensure that the option Personal Information Exchange - PKCS #12 (.PFX) is selected.

  5. On the Password page, specify a strong password to protect the exported certificate with its private key, and then click Next.

  6. On the File to Export page, specify the name of the file that you want to export, and then click Next.

  7. To close the wizard, click Finish in the Certificate Export Wizard page, and click OK in the confirmation dialog box.

  8. Close Certificates (Local Computer).

  9. Store the file securely and ensure that you can access it from the Configuration Manager console.

The certificate is now ready to be imported when you create a cloud-based distribution point.

This certificate deployment has the following procedures:

  • Creating and Issuing the Workstation Authentication Certificate Template on the Certification Authority

  • Configuring Autoenrollment of the Workstation Authentication Template by Using Group Policy

  • Automatically Enrolling the Workstation Authentication Certificate and Verifying Its Installation on Computers

This procedure creates a certificate template for System Center 2012 Configuration Manager client computers and adds it to the certification authority.

  1. On the member server that is running the Certification Authority console, right-click Certificate Templates, and then click Manage to load the Certificate Templates management console.

  2. In the results pane, right-click the entry that displays Workstation Authentication in the column Template Display Name, and then click Duplicate Template.

This procedure configures Group Policy to autoenroll the client certificate on computers.

  1. On the domain controller, click Start, click Administrative Tools, and then click Group Policy Management.

  2. Navigate to your domain, right-click the domain, and then select Create a GPO in this domain, and Link it here.

    noteNote
    This step uses the best practice of creating a new Group Policy for custom settings rather than editing the Default Domain Policy that is installed with Active Directory Domain Services. By assigning this Group Policy at the domain level, you will apply it to all computers in the domain. However, on a production environment, you can restrict the autoenrollment so that it enrolls on only selected computers by assigning the Group Policy at an organizational unit level, or you can filter the domain Group Policy with a security group so that it applies only to the computers in the group. If you restrict autoenrollment, remember to include the server that is configured as the management point.

  3. In the New GPO dialog box, enter a name for the new Group Policy, such as Autoenroll Certificates, and click OK.

  4. In the results pane, on the Linked Group Policy Objects tab, right-click the new Group Policy, and then click Edit.

  2. Log on with an account that has administrative privileges.

  3. In the search box, type mmc.exe., and then press Enter.

  4. In the empty management console, click File, and then click Add/Remove Snap-in.

  5. In the Add or Remove Snap-ins dialog box, select Certificates from the list of Available snap-ins, and then click Add.

  6. In the Certificate snap-in dialog box, select Computer account, and then click Next.

  7. In the Select Computer dialog box, ensure that Local computer: (the computer this console is running on) is selected, and then click Finish.

  8. In the Add or Remove Snap-ins dialog box, click OK.

  9. In the console, expand Certificates (Local Computer), expand Personal, and then click Certificates.

  10. In the results pane, confirm that a certificate is displayed that has Client Authentication displayed in the Intended Purpose column, and that ConfigMgr Client Certificate is displayed in the Certificate Template column.

  11. Close Certificates (Local Computer).

  12. Repeat steps 1 through 11 for the member server to verify that the server that will be configured as the management point also has a client certificate.

The computer is now provisioned with a Configuration Manager client certificate.

noteNote
This certificate can also be used for media images that do not use PXE boot, because the certificate requirements are the same.

This certificate deployment has the following procedures:

  • Creating and Issuing a Custom Workstation Authentication Certificate Template on the Certification Authority

  • Requesting the Custom Workstation Authentication Certificate

  • Exporting the Client Certificate for Distribution Points

This procedure creates a custom certificate template for Configuration Manager distribution points that allows the private key to be exported, and adds the certificate template to the certification authority.

noteNote
This procedure uses a different certificate template from the certificate template that you created for client computers, because although both certificates require client authentication capability, the certificate for distribution points requires that the private key is exported. As a security best practice, do not configure certificate templates to allow the private key to be exported unless this configuration is required. The distribution point requires this configuration because you must import the certificate as a file, rather than select it from the certificate store.

By creating a new certificate template for this certificate, you can restrict which computers request a certificate that allows the private key to be exported. In our example deployment, this will be the security group that you previously created for Configuration Manager site system servers that run IIS. On a production network that distributes the IIS site system roles, consider creating a new security group for the servers that run distribution points so that you can restrict the certificate to just these site system servers. You might also consider adding the following modifications for this certificate:

  • Require approval to install the certificate, for additional security.

  • Increase the certificate validity period. Because you must export and import the certificate each time before it expires, increasing the validity period reduces how often you must repeat this procedure. However, when you increase the validity period, it decreases the security of the certificate because it provides more time for an attacker to decrypt the private key and steal the certificate.

  • Use a custom value in the certificate Subject field or Subject Alternative Name (SAN) to help identify this certificate from standard client certificates. This can be particularly helpful if you will use the same certificate for multiple distribution points.

  1. On the member server that is running the Certification Authority console, right-click Certificate Templates, and then click Manage to load the Certificate Templates management console.

  2. In the results pane, right-click the entry that displays Workstation Authentication in the column Template Display Name, and then click Duplicate Template.

  3. In the Duplicate Template dialog box, ensure that Windows 2003 Server, Enterprise Edition is selected, and then click OK.

    ImportantImportant
    Do not select Windows 2008 Server, Enterprise Edition.

  4. In the Properties of New Template dialog box, on the General tab, enter a template name to generate the client authentication certificate for distribution points, such as ConfigMgr Client Distribution Point Certificate.

  5. Click the Request Handling tab, and select Allow private key to be exported.

  6. Click the Security tab, and remove the Enroll permission from the Enterprise Admins security group.

  7. Click Add, enter ConfigMgr IIS Servers in the text box, and then click OK.

  8. Select the Enroll permission for this group, and do not clear the Read permission.

  9. Click OK and close Certificate Templates Console.

  10. In the Certification Authority console, right-click Certificate Templates, click New, and then click Certificate Template to Issue.

  11. In the Enable Certificate Templates dialog box, select the new template that you have just created, ConfigMgr Client Distribution Point Certificate, and then click OK.

  12. If you do not have to create and issue any more certificates, close Certification Authority.

This procedure requests and then installs the custom client certificate on to the member server that runs IIS and that will be configured as a distribution point.

  1. Click Start, click Run, and type mmc.exe. In the empty console, click File, and then click Add/Remove Snap-in.

This certificate deployment has the following procedures:

  • Creating, Issuing, and Installing the AMT provisioning certificate

  • Creating and Issuing the Web Server Certificate for AMT-Based Computers

  • Creating and Issuing the Client Authentication Certificates for 802.1X AMT-Based Computers

Create the provisioning certificate with your internal CA when the AMT-based computers are configured with the certificate thumbprint of your internal root CA. When this is not the case and you must use an external certification authority, use the instructions from the company issuing the AMT provisioning certificate, which will often involve requesting the certificate from the company’s public Web site. You might also find detailed instructions for your chosen external CA on the Intel vPro Expert Center: Microsoft vPro Manageability Web site (http://go.microsoft.com/fwlink/?LinkId=132001).

ImportantImportant
External CAs might not support the Intel AMT provisioning object identifier. When this is the case, use the alternative method of supplying the OU attribute of Intel(R) Client Setup Certificate.

When you request an AMT provisioning certificate from an external CA, install the certificate into the Computer Personal certificate store on the member server that will host the out of band service point.
