The first issues with citrix are related to openmotif because the package is not available in the fedora server. The package can be obtained from this source: http://rpm.pbone.net/index.php3/stat/3/srodzaj/1/search/openmotif
But before installing openmotif in necessary to install the dependences, those files can be found in the same page.
Then everything looks great, however the certificates will not be available. This problem has several years. The last known solution was to get the certificates from the mozilla directory on /usr/share/ca-certificates/mozilla/ . But the Red Hat guys reorganized everything and now it is on the folder /etc/pki/tls/certs/ca-bundle.crt
It is on a rpm package so it wont work, so the other way is to google the specific certificate , it should be a package .crt or .cer. Then to put this file into /usr/lib/ICAClient/keystore/cacerts/
Thats the only way, to get the certificate from somewhere and place it on /usr/lib/ICAClient/keystore/cacerts/
