I wish to log on to our system at work from home. I have the crypto card and correct address, my usename and password. I have installed Citrix ICA client but when I try to log on to work through the secure website, I receive the message: "you have not chosen to 'entrust.net Security Server Certification Authority', the issuer of the server's security certificate."

Can anyone tell me how to correct this problem? It used to work. And my Windows XP office computer works. I am running Linux 11.2. Our help desk has not helped as they are familiar with Windows not Linux.

Hope you can help.
