@rabati:
Just a few questions for you:
What sort of errors do you get in Address Book? Are you hosting Zimbra yourself, or using a hosted service? Are you getting any errors in the Directory Utility?
If you want to be bold about it, you may be able to glean some useful information about the LDAP connection (at least if it's unencrypted - which I'd usually discourage) using tcpdump (from a Terminal window). Otherwise, have you checked your Console log to see if either Address Book or the Directory Utility have output any messages there? |
