Before anything, I have to admit that Zimbra is pretty darn exciting suite to have in a organization.

Anyway, I'm in a bit of dilemma here. I'm a sysadmin for a private school and we have a few hundreds student for every year. All the students are required to log in via Open Directory (LDAP) mechanism running of OS X Server. Managing (adding/deleting/modifiying) hundreds of users is a breeze using the supplied Workgroup Manager for OSXS.

But, wanting to give more for the students and teachers alike, Zimbra is an obvious choice. However, Zimbra's tight integration with its own LDAP for user management is a bit troubling (or whatever else that are already running on the server)

Is there an (relatively) easy way to run Zimbra and connect it to existing server?

(Finger crossed) Hopely, the great folks at Zimbra could say "Yes!" or at least offer some guideline to do so.
