Hi All, I'm running Samba 3.0.22-1 on Fedora Core 5 as a PDC for a single domain on our network, which consists of about 50 machines at 9 sites across the state (so far). We're moving email to an Exchange 2003 server, which is going to force me to move to AD in one form or another. Samba is currently running in tdbsam mode (it was a quick and dirty setup issue at the time) and all users are domain users with local profiles. This is all working quite well today, but I now need to support Exchange 2003. I have been unsuccessful in migrating Samba tdbsam to LDAP to-date - not sure of the problem just yet. But what I'm really after is how to: 1. Migrate all users from the tdbsam to a new Windows AD on a new W2k3 server - possibly with a different domain name 2. Migrate users and workstation accounts in-place without loss of ACLs, user settings, SIDs, and profiles. I don't care about passwords - I can reset those as needed after migration. I've read how to do various migrations in many places, but as yet I have not found my exact situation described, nor have I found a discussion or step-by-step instructions about how to proceed. For example, I believe I need to have LDAP working in order to use the various domain migration tools by both MS and open-source, correct? The goal is to prevent me from having to travel to migrate all users manually at all offices, and reduce the impact to the end users. I do have other machines that I can temporarily use to migrate, but I do not really know what the steps might be to get SID history and other info (if I need that) to minimize hitting every workstation across the state. I'd like to get this all set up and migrate office by office, adding people to Exchange in the process. It would be better if I could migrate them through a logon script or some other hands-off way as all of these sites, except where I sit in HQ, are remote and do not have IT help. Can anyone show me the steps/options or point me to more tutorials that fit my scenario? And please don't just tell me I should use Samba unless it can reduce my administrative overhead in managing the domain and Exchange - I'm looking for integrated administration tools. I'd prefer to stay with Samba, but it's just not that simple in this case. Thanks. - Gordon Cunningham
