If you are running a multi-tenant system, all Tenant URLs must be in the same domain, and each use a unique sub-domain. You then also use a wildcard or SAN SSL certificate. For a wildcard certificate, you must substitute an asterisk (*) wildcard character for the tenant sub-domain name (or sub-sub-domain name) in the Common Name, so the name of each tenant automatically matches the fully qualified domain name (FQDN) for the certificate.

For example: *.example.com or *.portal.example.com.

If using a Subject Alternate Name (SAN) certificate, the alternate names are added by the Certificate Authority when a certificate is ordered and the Common Name you’re providing here in the Certificate Details portion of the screen is used to provide your base Common Name (CN) for your SAN certificate.

Microsoft refers to their own version of SAN certificates as Unified Communications (UC) certificates.



Vidyo recommends that you use sub-sub-domain names so that you can also use a wildcard DNS entry in your domain name server to resolve tenant URL addresses without requiring a separate entry for each tenant, and also avoid having to create a new DNS entry each time a new tenant is added.

The following screenshot shows some wildcard certificate entry examples:
