I still can't creat and Open Directory Master. My hostname is correct. I get to a screen where it has Directory Administrator for the name, diradmin for account name, and I put in the password I used to set this machine up and I still get the message about The hostname does not resolve to any configured address. Please ensure your hostname and network configuration."
I don't understand why I should change the host name. It has the same host name as the previous server which is what I want to keep.
Also, in reading the migration manual, my understanding is that the only way to import users and groups while maintining the passwords and such is to do an LDAP archive, which I did. When I try to use server admin on my Lion server and use the archive feature to restore from my LDAP backup, I can't because it will only work for Open Directory masters. I am trying to make my Lion Server an OD master, but can't get anywhere.
The server migration is the worst I've ever seen in setting up a Mac. I just don't know where to go from here. It seems I can't get the OD master to work until I get the hostname resolved but I don't know what that means - resolved to what? It's exactly as I want it - the same host name as my previous server (which is not on the LAN anymore by the way so it can't interfere with this new server).
