The first thing to remember is that this is a .0 revision, meaning there are going to be miscues and problems. I've talked to Apple Enterprise about several other topics and they've been great, but I think they're having documentation issues as well.
I believe (my opinion only) that while 10.7 was pretty ready on the client side (there are still some issues), that Lion server was rushed a bit. It was in the press about holding up new hardware for the Lion release. People normally will wait to purchase if a new hardware release is imminent. So I think the documentation is lacking to some degree because of that.
If you don't have it, here's the link to the Advanced Server Administration for Lion: https://help.apple.com/advancedserveradmin/mac/10.7/#
