Want to test? Go for it!! Here's how to bypass the browser check
Code:
su - zimbra
zmmailboxdctl stop
Edit:
Code:
/opt/zimbra/jetty/webapps/zimbra/ZimbraWebClient/WebRoot/public/launchZCS.jsp
and comment out:
Code:
switchToStandardClient();
(around line 199)
Code:
rm -rf /opt/zimbra/jetty/work/*
zmmailboxdctl start
A few usual warnings:
1) Not supported, so if you bust it, it's your fault

2) Make sure you use a unix editor (not wordpad)
3) Do not rm -rf the work dir while jetty is running. You won't like the results

4) If something happens, and you totally bust it, rerun your installer with ./install.sh -s
Have fun! Report bugs so we can support it too!
