Active Directory Certificate Services Step by Step Guide. To test additional features of AD CS in a lab environment, you will need five computers running Windows Server 2. Windows Vista. The computers for this guide are named as follows. TESTDC1 This computer will be the domain controller for your test environment. TESTCAROOT1 This computer will host a stand alone root CA for the test environment. TESTCAISSUE1 This enterprise CA will be subordinate to TESTCAROOT1 and issue client certificates for the Online Responder and client computers. Note. Enterprise CAs and Online Responders can only be installed on servers running Windows Server 2. Install Xampp In Ubuntu Terminal Program there. Enterprise or Windows Server 2. Datacenter. TESTORS1. This server will host the Online Responder. TESTNDES. This server will host the Network Device Enrollment Service that makes it possible to issue and manage certificates for routers and other network devices.

TESTCLI1 This client computer running Windows Vista will autoenroll for certificates from TESTCAISSUE1 and verify certificate status from TESTORS1. To configure the advanced lab setup for AD CS, you need to complete the following prerequisite steps. Set up a domain controller on TESTDC1 for contoso. OUs to contain one or more users for TESTCLI1, client computers in the domain, and for the servers hosting CAs and Online Responders. Install Windows Server 2. Install Windows Vista on TESTCLI1, and join TESTCLI1 to contoso. After you have completed these preliminary setup procedures, you can begin to complete the following steps Step 1 Setting Up the Stand Alone Root CAStep 2 Setting Up the Enterprise Subordinate Issuing CAStep 3 Installing and Configuring the Online Responder. Step 4 Configuring the Issuing CA to Issue OCSP Response Signing Certificates. Step 5 Configuring the Authority Information Access Extension to Support the Online Responder. Step 6 Assigning the OCSP Response Signing Template to a CAStep 7 Enrolling for an OCSP Response Signing Certificate. Step 8 Creating a Revocation Configuration. Step 9 Setting Up and Configuring the Network Device Enrollment Service. Step 1. 0 Verifying that the Advanced AD CS Test Setup Functions Properly. A stand alone root CA is the anchor of trust for the basic lab setup. It will be used to issue certificates to the subordinate issuing CA. Because it is critical to the security of the public key infrastructure PKI, this CA is online in many PKIs only when needed to issue certificates to subordinate CAs. Log on to TESTCAROOT1 as an administrator. Start the Add Roles Wizard. On the Select Server Roles page, select the Active Directory Certificate Services check box, and then click Next two times. On the Select Role Services page, select the Certification Authority check box, and then click Next. On the Specify Setup Type page, click Standalone, and then click Next. On the Specify CA Type page, click Root CA, and then click Next. On the Set Up Private Key and Configure Cryptography for CA pages, you can configure optional settings, including cryptographic service providers. However, for basic testing purposes, accept the default values by clicking Next twice. In the Common name for this CA box, type the common name of the CA, Root. CA1, and then click Next. On the Set the Certificate Validity Period page, accept the default validity duration for the root CA, and then click Next. On the Configure Certificate Database page, accept the default values or specify other storage locations for the certificate database and the certificate database log, and then click Next. After verifying the information on the Confirm Installation Options page, click Install. Most organizations use at least one subordinate CA to protect the root CA from unnecessary exposure. An enterprise CA also allows you to use certificate templates and to use AD DS for enrollment and publishing certificates. Log on to TESTCAISSUE1 as a domain administrator. Start the Add Roles Wizard. On the Select Server Roles page, select the Active Directory Certificate Services check box, and then click Next two times. On the Select Role Services page, select the Certification Authority check box, and then click Next. On the Specify Setup Type page, click Enterprise, and then click Next. On the Specify CA Type page, click Subordinate CA, and then click Next. On the Set Up Private Key and Configure Cryptography for CA pages, you can configure optional settings, including cryptographic service providers. However, for basic testing purposes, accept the default values by clicking Next twice. On the Request Certificate page, browse to locate TESTCAROOT1, or if, the root CA is not connected to the network, save the certificate request to a file so that it can be processed later. Click Next. The subordinate CA setup will not be usable until it has been issued a root CA certificate and this certificate has been used to complete the installation of the subordinate CA. In the Common name for this CA box, type the common name of the CA, TESTCAISSUE1. On the Set the Certificate Validity Period page, accept the default validity duration for the CA, and then click Next. On the Configure Certificate Database page, accept the default values or specify other storage locations for the certificate database and the certificate database log, and then click Next. After verifying the information on the Confirm Installation Options page, click Install. An Online Responder can be installed on any computer running Windows Server 2. Enterprise or Windows Server 2. Datacenter. The certificate revocation data can come from a CA on a computer running Windows Server 2. CA on a computer running Windows Server 2. Microsoft CA. An Online Responder will typically not be installed on the same computer as a CA. Note. IIS must also be installed on this computer before the Online Responder can be installed. As part of the setup process a virtual directory named OCSP is created in IIS and the Web proxy is registered as an Internet Server Application Programming Interface ISAPI extension. Log on to TESTORS1 as an administrator. Start the Add Roles Wizard. On the Select Server Roles page, select the Active Directory Certificate Services check box, and then click Next two times.

As with any certificate template, the OCSP Response Signing template must be configured with the enrollment permissions for Read, Enroll, Autoenroll, and Write before any certificates can be issued based on the template. Log on to TESTCAISSUE1 as a CA administrator. Open the Certificate Templates snap in. Right click the OCSP Response Signing template, and then click Duplicate Template. Type a new name for the duplicated template, such as OCSP Response Signing2. Right click the OCSP Response Signing2 certificate template, and then click Properties. Click the Security tab. Under Group or user name, click Add, and type the name or browse to select the computer hosting the Online Responder service. Click the computer name, TESTORS1, and in the Permissions dialog box, select the Read and Autoenroll check boxes.
