Verify Certificate


Certificates are used on secure servers as part of their security. At Queen's, Entrust Certificates are used for some hosts including,,, and


Mac OS X does not recognize Entrust as a Root Certificate issuer. This causes a warning when the operating system accesses a site with a certificate signed by Entrust. Therefore, when you are accessing Queen's sites  that use Entrust Certificates, you will get a warning. You can manually tell your browser that the site is safe by following the instructions below.



  1. When accessing a site that uses an Entrust certificate the Verify Certificate screen will open 
    • Click the Show Certificate button
  2. The Verify Certificate screen will expand to show you the Certificate
    • Click the Details link
  3. The Verify Certificate screen will expand to show the details for the certificate 
    • In the Subject Name section verify that you are going to a Queen's site
    • In the Issuer Name  section verify that the certificate comes from Entrust, Inc.
    • Check the box beside Always trust "" when connecting to ""
    • Click the Continue button
  4. The Password screen will open 
    • The Name: field should already be filled in
    • In the Password: field enter your password. This is your user account password that you use for things like installing software.
    • Click the OK button
  5. You will not have to verify this certificate again until the certificate expires.  This usually happens every 1-2 years.

Note:  You may have to repeat this procedure for other sites at Queen's that use Certificates from Entrust.
