Verisign certificate issue in Safari (Citrix)

I been given access from my job to be able to connect from Home. I installed the certificate in Key chain access and appears to be valid. When i launch Safari and access the secure site.... Https://vpn......ca. I get a pop up that says you have not trusted the Verisign certificate which expires in 2012 and below shows the VPN site. I click trust then it appears again but instead of it showing the VPN site... it says Citrix system.inc and that expired in 2005. When i use Firefox, It works perfectly fine. I also added the certificate in Macintosh HD: Applications: Citrix ICA Client: Keystore :cacerts. Without this I get the verisign certificate error. Does anyone know how to get it to work in Safari?

thanks
