Security tip

For security reasons, it is advisable to configure enrollment agent restrictions for a CA to allow only the newly created Enrollment Agent User permissions to enroll certificates on behalf of the users. To do so, follow the steps below.

1. Open the Certification Authority snap-in, right-click the name of the CA, and then click Properties.
2. Click the Enrollment Agents tab, click Restrict enrollment agents, and click OK on the message that appears.
3. Under Enrollment agents, click Add, type the name of the Enrollment agent user created in the previous steps and then click OK. Click Everyone, and then click Remove.
4. Under Certificate Templates, click Add, select the templates that were created (Prls Enrollment Agent and Prls Smartcard Logon) and then click OK. When you have finished adding the names of certificate templates, click <All>, and then click Remove.
5. Under Permissions, click Add, type the names or groups, which are the users or group expected to login to the RAS environment using SAML, and then click OK. Click Everyone, and then click Remove.
6. If you want to block the enrollment agent from managing certificates for other users, computers, or groups, under Permissions, select this user, computer, or group, and then click Deny.
7. When you are finished configuring enrollment agent restrictions, click OK or Apply.

Note: The user or group that you applied enrollment agent restrictions to must have a valid enrollment agent certificate for the CA before they can act as an enrollment agent, whether restricted enrollment agent permissions have or have not been configured.
