In the following dialog box, click *Yes*, and the certificate will appear in the certificate list on the *Server Certificates* tab. To make the added certificate trusted, select it from the certificate list and click the Trust button.

For the changes to take effect, they need to be synchronized with the server by pressing the *Sync* button or the F5 key.
