File Director


File Director SAN certificates

This section provides information about configuring a File Director certificate that contains SAName entries.

Subject Alternative Name (SAN) extensions allow a certificate subject to be associated with the service name and domain name components of a DNS Service Resource Record. This enables us to publish multiple DNS names using one SSL web listener.

This allows administrators to use CNAME alias DNS records with an SSL certificate that has a different Common Name set within the subject of the certificate.

This section assumes that you have a functioning File Director appliance with a base DNS, AD, admin user and license configuration applied already.

The configuration is in three parts, DNS, General Certificate and File Director Appliance.

In this section:
