View source for SSL error with Citrix ICA client on Linux

'''Problem:'''
* The Citrix ICA client does not connect to your corporate network.
* After launching the client it displays the following error message:
 You have chosen not to trust “<CA which is used by your corporate network>”, the issuer of the server’s security certificate (SSL error 61).

'''Solution:'''
* The Linux version of the Citrix ICA client brings only a small set of root CAs which are trusted.
* Add the additional CAs which are required by copying the certificates to the following directory:
 sudo cp <AnyCA.crt> /opt/Citrix/ICAClient/keystore/cacerts/
* Alternatively create symlink to the system ca-certificates:
 sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
* Finally run the following command to rehash the certificates and you should be fine...
 sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/
