    Configure Authentication with a Single Custom Certificate for a WildFire Cluster

    Assign and push a single, shared certificate to an entire WildFire® cluster.
    Instead of assigning unique certificates to each WildFire® appliance in a cluster, you can assign a single, shared client certificate to the entire WildFire cluster, which, in turn, allows you to push a single certificate to all WildFire appliances in the cluster instead of configuring separate certificates for each cluster member. Because the individual WildFire appliances share a client certificate, you must configure a unique hostname (DNS name) for each WildFire appliance. Then you can add all the hostnames as certificate attributes to the shared certificate or use a one-wildcard string that matches all the custom hostnames on all the WildFire appliances in the cluster.
    To configure a single custom certificate for your WildFire cluster to use when communicating with the Panorama™, complete the following procedure.
    1. Obtain a server key pair and CA certificate for Panorama.
    2. Configure a certificate profile that includes the root certificate authority (CA) and the intermediate CA. This certificate profile defines the authentication between the WildFire cluster (client) and the Panorama appliance (server).
      1. Select PanoramaCertificate ManagementCertificate Profile.
      2. Configure a certificate profile.
        If you configure an intermediate CA as part of the certificate profile, you must also include the root CA.
    3. Configure an SSL/TLS service profile.
      1. Select PanoramaCertificate ManagementSSL/TLS Service Profile.
      2. Configure an SSL/TLS service profile to define the certificate and protocol that the WildFire cluster and Panorama appliance use for SSL/TLS services.
    4. Connect each node in the cluster to Panorama.
    5. Configure a unique hostname (DNS name) on each node in the cluster or use a string with a single wildcard that matches all custom DNS names set on the WildFire appliances in the cluster.
      If using a single-wildcard string, see RFC-6125,Section 6.4.3 for requirements and limitations of wildcard string values. Make sure you understand these requirements and limitations when configuring your custom DNS names.
      1. Log in to the WildFire CLI on a node.
      2. Use the following command to assign a unique custom DNS name to the node.
        admin@WF-500> configure
        admin@WF-500# set deviceconfig setting wildfire custom-dns-name <dns-name>
      3. Commit your change.
      4. Repeat this process for each node in the cluster.
    6. On Panorama, generate a client certificate for all nodes in the cluster. Under Certificate Attributes, add a hostname entry for each custom DNS name you assigned to the cluster nodes or add one hostname entry with a one-wildcard string that matches all of the node hostnames, such as *.example.com; you can do this only if each custom DNS name shares a common string.
    7. On Panorama, configure the certificate profile for the cluster client certificate.
      1. Select PanoramaCertificate ManagementCertificate Profile for Panorama.
      2. Configure a Certificate Profile.
    8. Deploy custom certificates on each node. This certificate profile must contain the CA certificate that signed the Panorama server certificate.
      1. Select PanoramaManaged WildFire Clusters and click on the cluster name.
      2. Select Communications.
      3. Under Secure Client Communications, select the Certificate Type, Certificate, and Certificate Profile.
      4. Click OK.
      5. Commit your changes.
    9. Configure secure server communication on Panorama.
      1. Select PanoramaSetupManagement and Edit to select Customize Secure Server Communication.
      2. Enable Customize Secure Server Communication.
      3. Select the SSL/TLS Service Profile. This SSL/TLS service profile applies to all SSL connection between WildFire and Panorama.
      4. Select the Certificate Profile for Panorama.
      5. Enable Custom Certificates Only.
      6. Click OK.
      7. Commit your changes.
