Loading a Trusted CA Certificate to a CTERA Edge Filer

When the object storage used by the CTERA Portal is accessed by Direct Mode and uses a X.509 Certificate signed by a private Certification Authority (a self-signed certificate) and not a public trusted certificate, this certificate must be uploaded to the CTERA Edge Filer. You upload the certificate using the following procedure that requires a REST client tool such as Postman or HTTPie.

To upload a self-signed certificate to the CTERA Edge Filer:

1. Get the certificate used by the object storage.

2. Launch the REST client.

3. Log in to the CTERA Edge Filer with the following REST API, using HTTPS: https://edgefiler_IP/admingui/api/ login with the following:
   HTTP Method – POST
   Request Content-Type – application/x-www-form-urlencoded
   Request Body

   • username – username
   • password – password
     
     

   Expected Response Status – 200 OK and an HTTP session cookie which is then used for the duration of the session.
   The session times out after 30 minutes of inactivity. If a response such as 403 Forbidden is returned, check the user name and password provided.

   Where:
   edgefiler_IP – The IP address of the CTERA Edge Filer.
   username – Mandatory: The name of a user with administrative rights to the gateway. This is the username set in the procedure in Initial CTERA Edge Filer Setup.
   password – Mandatory: The password for the user. The login is over HTTPS to ensure that the password is encrypted. This is the password set in the procedure in Initial CTERA Edge Filer Setup.
   Upon receiving a successful login reply, the server sets HTTP session cookies. The client must return these cookies to the server in the next request.

4. Copy to your clipboard the contents of the certificate.

5. Upload the certificate using the following REST API: http://edgefiler_IP/admingui/api/config/extStorageTrustedCA?put with the following:
   HTTP Method – POST
   Request Content-Type – application/xml
   Request Body

   <obj class="ExtStorageTrustedCA">
       <att id="certificate">
            <val>
   -----BEGIN CERTIFICATE-----
   ##### Certificate Content #####
   -----END CERTIFICATE-----
           </val>
         </att>
   </obj>
   

   Expected Response status – 200 OK

   Where:
   edgefiler_IP – The IP address of the CTERA Edge Filer.
   Certificate Content – The certificate content that was copied to the clipboard.
