I am evaluating Zimbra 6.04 for possibly replacing an Exchange 2003 server.

We are running all Macs and moving to Snow Leopard.

I have Mail and iCal set up with IMAP and CalDAV and they are working fine.

I am trying to get Address Book connected to Zimbra. When trying to use CardDAV I get an error saying it couldn't discover the cardDAV server.

I have also tried to set up LDAP, but it doesn't return anything.

Any ideas?
