Problem

When attempting to connect to Citrix from a Mac, you recieve the following error message:

SSL Error 0: You have not chosen to trust
"Entrust.net Secure Server Certification Authority",
the issuer of the server's security certificate.
Error number: 183 

Solution 1

  • Download Media:Keystore.dmg.zip
  • Double click on the downloaded file to "unzip" it.
  • Double click on the file keystore.dmg
  • Replace your existing Keystore folder with the new one that appears in the disk "keystore"
  • (Keystore is located in /Applications/Citrix ICA Client/
  • Move keystore.dmg.zip, keystore.dmg and the disk "keystore" to the trash

Solution 2

1) Make sure that Citrix ICA Client is installed. You can download it here: Citrix ICA Client

2) Go to entrust.net/developer and click on Download Root Certificates

3) Select Personal Use, and click on Download Certificates

4) Download entrust_ssl_ca.cer and entrust_ssl_ca.der to your desktop

5) Open a terminal, and enter the following:

cd /Applications/Citrix\ ICA\ Client/keystore/cacerts/
cp -p ~/Desktop/entrust_ssl_ca.* .
ln -s entrust_ssl_ca.cer entrust_ssl_ca.crt

6) Exit the terminal, and try your Citrix session again.


Note

We are in the process of producing a new Mac OS X installation package that will include this certificate file. This should prevent this issue from occurring in the future.
