I run a mostly Mac based network, and some of my users have moved to OS X 10.5 (Leopard) which has Safari 3.0.4 preinstalled. Users can't log into my zimbra web app with the new version, they get the error:
"An unknown application error has occurred. Please correct any errors and retry. If the problem persists, please contact your System Administrator. (service.PARSE_ERROR)"
I saw in an earlier thread this exact problem with the beta release of Safari 3, but I wondered if there is a fix for it? I'm on the OSS version of Zimbra: 4.5.9_GA_1454.
For now, I'm advising my users to use firefox, which continues to work fine.
