    If you chose a domain certificate, the domain name might be, where company01 is the name of your virtual portal.
    If multiple virtual portals are configured, each virtual portal has its own DNS name. In this case, the SSL certificate should be a wildcard certificate with an asterisk before the DNS suffix, for example, *
    If you have only one portal, and do not intended to configure multiple virtual portals, then use a regular SSL certificate and not a wildcard certificate.
    To request a certificate that specifies multiple alternative names, type the multiple names in this field, separated by semicolons. The certificate will include the subjectAltName certificate extension.
  5. Optionally, specify the following:
    Organizational Unit – The name of your organizational unit.
    Organization – The name of your organization.
    Email – Your email address.
    City – Your city.
    State – Your state.

    The Certificate Request area of the SSL Certificate window indicates that the certificate request is pending.

When you generate a CSR, a private.key file is registered in the CTERA Portal. If you now generate a new CSR, it will override the existing private.key file, and signing the old CSR will result in an error message indicating that the CSR does not match the private.key file. Therefore, do not generate a new CSR before installing the signed certificate.
