Seeing that Zimbra released a beta version of their Novell Evolution connector two weeks back, I went ahead and downloaded the code from their SVN server. Today, I have created a package for Ubuntu 7.04 (aka Ubuntu Feisty) that integrates nicely with Evolution 2.10. My unscientific testing shows that it indeed works as expected but some small improvements are needed to polish it up further.

You can download the source and binary packages below:

UPDATE: I have researched the problems that I and some other folks were having with syncing contacts and calendars locally to the server. I have found that curl expects the CA certificate bundle to be available on the local machine before it verifies the authenticity of the remote SSL certificate coming from Zimbra. Since we don't have the Zimbra CA certificate installed, we will never authenticate with the server. I have created new packages that have disabled curl's ability to verify authenticity until a better solution can be found.
