Using CACert as a CA in Zimbra

Which platform were you using when putting together this guide? It looks useful, but I believe the first few steps will be different depending on the platform. For example, the /opt/zimbra/java/jre/ path does not exist on a Mac OS X install, so by definition the path mentioned near the beginning of the guide also does not exist:

/opt/zimbra/java/jre/lib/security/cacerts

My guess, and that's all it is at the moment, is that the relevant location for Mac OS X might be here:

/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/lib/security/cacerts

Feel free to let me know if somebody can confirm or correct my guess... ;)
