When I try to log onto the Zimbra web interface from my Sun workstation at work I get the following error upon clicking login:

An unknown application error has occurred. Please correct any errors and retry. If the problem persists, please contact your System Aministrator. (service.PARSE_ERROR)

I'm able to log on with my Mac and my windows box.. Are there any known issues with running Zimbra's web client on Solaris?

I've tried Sun's Mozilla and Firefox 1.0.4 with no success.
