I'm running CM 4.02a(sr2c)on 8 CM's in a cluster. I'm AD integrated for the Corporate Directory function. The server group is upgrading to Active Directory 2003. Has anyone done this and are there any known issues with Call Manager integrating with AD 2K3? I've also got 2 IPCC Express servers, 3 IPIVRs, and 1 Conference Connect server - all of which are AD integrated. Any ideas if this will pose a problem.
