I managed to add the zentyal server as an additional server to my server 2008 AD in file sharing and users / groups replicate ok although frustratingly it doesn't replicate from any other OU apart from the Users container which is a serious issue for me.
I have users defined under (for example) a 'MyUsers' OU and then OU's underneath for Departments so I can apply Group Policies, Security Groups are also defined in another OU for ease of adminstration.
I can't see how I'm going to migrate from the old AD Sync type method ( I would like to
) where all my users and groups are replicated from all containers and OU's from the top of the AD Tree.
Any suggestions ?
