Solution: SSL Error Citrix Receiver - Error 61 - You have not chosen to trust "/C=US/ST=/L=/0=Equifax/OU=Equifax Secure Certificate Authority/CN=", the issuer of the server's security certificate (SSL error 61).
====================================
Solution.
1. Visit the GeoTrust Certificate Authority Web Site. Here is the URL of the exact page you need to visit: http://www.geotrust.com/resources/root-certificates/index.html
2. Near the top of the page, there are two links to verify Equifax's certificate. Right click the lower of the two links. Chose 'save' from the context sensitive menu that you'll see upon right clicking the lower of the two URLs associated with Equifax. You want the 'der' encoded x.509 certificate.
3. Rename the .cer to .crt.
4. As root copy the file from its saved download location to /opt/Citrix/ICAClient/keystore/cacerts/
** Step 4. In a console, bash shell, navigate to the folder that contains the saved/downloaded certificate: type sudo cp Equifax_* /opt/Citrix/ICAClient/keystore/cacerts/
5. You're done and now should be able to open your ".ica" files
