Open Directory and Zimba 7.2 GA Open Source?

[ericmachine]

Hi everyone,
I am new to Zimbra and plan to install the open source version soon.
Few questions:-
a. I assume the Open Source version can use this connector to access Open Directory. Am I right? If not, where can I buy and how much?
b. Can Zimbra authenticate with Lion Server Open Directory?
c. Can it work with the new Mountain Lion Server Open Directory too?
Note: My office, everyone using Mac Book Pro and iMac (all lion except 1 mountain lion). We will soon upgrade to mountain lion. At the same time, we plan to purchase Mountain Lion server to manage our computers. I need to make sure Zimbra works with the open directory.
Any help? Thanks in advance.
