We have Zimbra 4.5.7 running to what we believe is a max of 75 user licenses (single server implementation), and would like to implement Active Directory (AD) across the organization. This is being done for better management of the Windows-based users, and it's compatability with Mac Users. Any suggestions on the "pit-falls" of implementing AD after the Zimbra server is in place?

I will put a list of more specific questions later. Just looking for some insight from anyone who may have attempted something similar.

One issue we are facing is a limitation of 75 user licenses in Zimbra. We will grow to more than that and may face implementing a second Zimbra server with Load Balancing. I will make another post about that, but obviously we would like to know if there are any issues implementing AD in an environment such as this with Zimbra already functioning.

Kindest Regards,
