no, your current mailboxes will stay as they are, they'll just authenticate externally, and actually you can have fallback authentication where if the user fails to authenticate to AD it can still authenticate locally to zimbra, but thats not something a lot of people want.
anyway, i'm not sure it will streamline your user creation/deletion, as users are not automatically provisioned in zimbra upon authenticating to AD. You still have to create the users in zimbra as well, and will have to delete them ther even after you've removed a user from AD. |
